Kroton was a Cyberman who retained his human emotions. After turning against his species, he would go off on several adventures on his own - before briefly becoming a companion of the Eighth Doctor, alongside Izzy Sinclair.
Kroton showed an appreciation of beauty as well as the knowledge of what was right. It was this judgement that led him to fight back against oppressors - such as the Cybermen and the Sontarans. Originally having an innocence about him that could be described as child-like, he became more confident and slightly egotistical. At one point while fighting pirates, he claimed he could carry a tune, play a round of golf and even tell the odd off-color joke or two. Izzy referred to Kroton as been "like a Borg, but with way more personality". (This is based on the classic comparison of the Cybermen and the Borg from fans of both the Doctor Who and Star Trek franchises).
Before been converted into a cyberman, Kroton had a wife called Shallia as well as having two children - a boy and a girl. He forgot them originally after his conversion, but would later remember them with help from Izzy giving him a mnemonic crystal.
Kroton appeared in several comics as the main character or one of the main characters. He also appeared as a cameo in the comic Thinktwice - appearing as part of the Tenth Doctor's memories. He was also mentioned by Iris Wildthyme as having once been a traveling companion with her - although this claim is yet to be verified.
The ThrowbackEditAfter his conversion into a Cyberman, Kroton was made into a Junior Cyberleader and told to assist with the destruction of the rebels on Mondaran - a planet which the Cybermen were several months into the conquest of. Arriving from Telos (after he'd already been accused of having a malfunction due to stating how he would miss seeing the sky on Telos), Kroton spared the life of a woman who was going to be killed by the Cybermen as well as showing a determination to understand emotions. His attempt to talk to the humans failed as they react in fear to him, although the fact he refused to kill them - as well as later stopping a Cyber Patrol from trying to find them - left the humans to wonder if he was actually good as he has acted differently from any cyberman they'd previously encountered.
The resistance was betrayed by a human called Zarach, who states there will be an uprising in three days. Sure enough, the uprising ending in failure with one of the humans, Pendar, been captured. However, Kroton takes him outside the city and releases him - much to Pendar's shock. As Pendar reports back to his allies at the west bridge about Kroton, Kroton begins to question himself - his brain seemingly unable to handle the situation. However, a Cyber Squad finds Kroton - after been sent to bring him in for repair - before trying to kill humans. At this point from hearing the command to eradicate the humans, Kroton snaps and attacks the Cybermen - killing them with his Cyber Gun. Although he thinks it would be best to report for termination for his actions, Pendar convinces him that he has emotions and should help the humans.
Coming up with a plan, the humans plan to escape with Kroton piloting a spacecraft. After gathering as many people as possible who will actually trust Kroton, the group begin - with Kroton cutting through the fence. Coming under attack, Kroton and the humans fight the Cybermen - getting on-board a battle cruiser and managing to take off. Heading for the Forest of Lorn on the other side of the planet (due to it been vast enough to be safe), Kroton drops the humans off but decides to use the little fuel left to leave Mondaran, as he feels he doesn't belong with the humans and his batteries are running out. Although Pendar tries to stop him, Kroton asserts that this is the best option. Escaping Mondaran, Kroton shuts himself down while the ship - devoid of fuel - floats through space. This event was later logged in the Time Lord records, which was found by the Fourth Doctor.
The Ship of FoolsEditSome time later, the battle cruiser containing Kroton floats into a green, miasmic cloud. Inside the cloud is another much larger vessel - a space liner called The Flying Dutchman II - which locks onto the ship and brings it aboard. On board the ship - which is populated by several humans on a pleasure cruise - the humans find Kroton on-board and recharge him. Kroton, upon waking up fully and learning where he is, is surprised to find the humans aboard don't fear him as they've never heard of Cybermen. When Kroton asks other questions, such as where the ship is going and how long has it been going, the answers he is given confuse him - although he notices the clock says 7:17 and isn't moving - with Leonart (one of the crew members who is blind) explaining that the clocks are all working fine but time itself isn't moving.
Learning more despite his confusion, Kroton eventually learns from Leonart that the ship isn't 'going anywhere' and that they are stuck in a time warp - which is what the miasmic cloud was that Kroton's ship and the Flying Dutchman II entered (the warp acting like a lateral stasis field). Furthermore, no-one knows how long the ship has been stuck in the time warp, which is driving everyone a bit crazy as they've been stuck in the time warp for ages with no news on friends or family - to which Kroton sympathizes as he has also been adrift for a long time with no idea how his humans friends on Mondaran are. Realizing the pilot may have information required for them to break free, Kroton and Leonart head for the bridge but find the door to the room locked. Heading back to his ship in the shuttle port, Kroton recovers his Cyber gun to help in getting through the locked door, with the passengers joining him with the renewed hope of getting out and returning to Earth - although one of the passengers (Cassandra) states she is having a premonition about what they are trying to do. Her husband Rolf, however, brushes off her premonition.
Sure enough, Kroton's Cyber gun is successful in blasting open the door. Learning after the door is opened that the pilot is a robot, Kroton attempts to learn what happened - with the robotic pilot explaining that due to a blowout in the 2nd and 3rd main fuel tanks, there was insufficient fuel to reach the intended destination and no inhabitable planets nearby - with the pilot flying into the time-warp to ensure the survival of the passengers - using the remaining fuel to maintain their position until they can be found and picked up. Checking the instruments, Kroton realizes the vortex is still moving and an inhabitable planet is now only three days away - with the fuel level sufficient to reach it. Tinkering with the pilot's electronics to allow it to obey him, Kroton follows Rolf's order to try for planet-fall, with the ship managing to exit the time warp. However, when Kroton checks the stellar positions to work out how long the ship has been in the time warp, he discovers to his horror that it has been there for 628 years - watching as the passengers quickly age and die, turning to skeletons as time catches up with them. Once more alone with just the robotic pilot, his regrets and his memories of the passengers, Kroton is left to wait as the ship heads towards the inhabitable planet.
Other AdventuresEditFollowing the events on the Flying Dutchman II, Kroton headed off on other adventures during his time alone - with him learning quickly that due to the Cybermen been such a hated species, many would quickly try to kill him on sight. During these adventures, Kroton's personality changed - with him becoming more used to using his emotions as well as becoming more confident and even witty at times; even when fighting various enemies. During his time alone, however, Kroton would occasionally experience faint memories of his past life - seeing images of places and people (most notably a woman who seemed important to him) but he cannot remember the names of any of them. Although he did want to remember, he felt it best not to, as he could not reclaim what he once had and that the feeling of remembering would be "the worst kind of torture". As such, he had come to believe it was better off to leave "some truths buried".
It was claimed by Iris Wildthyme that he had traveled with her - although due to Iris having a long history of claiming that her adventures were the same as the ones the Doctor had, it's possible she lied. It's possible as well that Kroton may have gone to the planet known as Paradise - at the same time that Abslom Daak and the Draconian prince Salander were looking for Harma, an Ice Warrior who Daak was friends with. (As the Cyberman's face cannot be seen, it's impossible to determine whether it's Kroton. However, considering the Cyberman is on its own, it's possible that it is Kroton).
A confirmed adventure that Kroton had was helping out a group of Technosmiths on Baroq VII. As a thank you for his help, the Technosmiths upgraded his armour - making it more resilient with both the ability to collect solar energy to recharge Kroton's batteries and an auto-repair function if he was injured. They also improved his speed and agility, with him no longer lumbering around like other Cybermen. Finally, they created a quarterstaff for him to use in combat - which he could also magnetize to his back to carry around. It's unbeknown if the Technosmiths incorporated Kroton's Cyber gun into the quarterstaff or if Kroton lost/broke it as he isn't shown using it anytime afterwards. The upgrades he was given would later aid him greatly after he had settled on a planet and befriended a more primitive human population, who he described as been more accepting than many 'modern' civilizations. During his time, he trained some of the humans in combat skills for if they were ever attacked, although he remained peaceful among them.
The threat came from the arrival of the Sontarans, who were preparing to colonize the planet. A squad infiltrated the village were Kroton was, before attacking the villagers. Realizing they weren't going to get a fight out of the humans, the Sontaran Field Major decides to initiate a genocide. However, Kroton appears and engages the Sontarans - easily beating them aside while their laser fire has no effect on his metal armour. In an attempt to stop Kroton, the Field Major grabs hold of a young boy and takes him hostage. However, the young boy uses the combat skills Kroton taught him to break free before Kroton himself battles the Field Major. Despite his efforts, the Field Major is outmatched and knocked out by Kroton due to him landing on his probic vent - much to the delight of the villagers. Realizing there will be more Sontarans, however, Kroton heads up a cliff after logically deducing that the Sontarans will be on higher ground.
Narrowly avoiding been shot by a Sontaran Tank, Kroton manages to get some leverage and forces the tank off the top of the cliff - with the war machine exploding as it hits the bottom. Continuing to search, Kroton finds the Sontaran ship - quickly realizing that due to the ship's size, the Sontarans will be planning to colonize the planet. Easily battering the two Sontarans at the door and two more in the inner airlock, Kroton proceeds inside and finds thousands of tanks - each containing a growing Sontaran. Knowing that they'll be helpless while in their tanks, Kroton sets to work on setting the ship's self destruct off. Although several of the Sontaran clones break out to try and stop him, Kroton is successful and smashes them aside as the ship's self destruct activates - Kroton getting away in time.
Back at the village, the Sontarans begin to 'melt' as a result of the bio energy feed from the ship been cut off - which Kroton compares to cutting an umbilical cord. Returning to the village, Kroton is greeted with a hero's welcome but realizes he cannot share it as the celebrations are only awakening old memories of what he has had and lost. As such, Kroton decides to leave - heading off on his own again.
At some point, Kroton was placed in a large package aboard the Qutrusian Cargo Freighter X-703, destined for the Phodosia Spaceport, in the hope of "posting himself to a 'less enlightened' sector of the galaxy" as the more primitive races were more trusting. However, as fate would have it, Kroton would have a much different destination.
Meeting the Doctor and IzzyEditDuring the Qutrusian Cargo Freighter's journey, it was attacked in the Madras System after been forced off-course by a pirate vessel known as The Magpie (led by Captain Grast Horstrogg). Led by first mate Mr Shakka, the pirates boarded the freighter - annihilating the Qutrusians aboard as well as crippling the engines, before been ordered by the captain to search all the cargo decks. In one of the cargo decks, however, the crew members came across a large crate that was labelled 'Machine Parts'. As the crew opened it, they were shocked to see Kroton and immediately attacked him. Their weapons were ineffective against the Cyberman, however, as Kroton retaliated with his superior combat skills while also letting off his own style of humor in the process - easily beating the pirates down.
With his adversaries dealt with, Kroton exited the cargo bay and decided to explore his surroundings - especially after been convinced the men he encountered weren't supposed to be on the ship. At the same time as the pirates had invaded, the Eighth Doctor and his companion Izzy had unexpectedly arrived on the same freighter (after intending to go to the Library of Alexandria) before been captured by one of the pirates. A swift change of plans came, however, when The Magpie was destroyed by an unexpected energy beam from within a nearby asteroid belt. Due to the shockwave hitting the freighter, the Doctor and Izzy were able to knock out the pirate who had captured them. Heading to the engine room, they found the engines had been crippled by the pirates. However, as Kroton headed towards the engine room as well, he was spotted by the Doctor. Due to his own encounters with the Cybermen, the Doctor shouted for Izzy to get out of the way before throwing a high voltage cable into Kroton's chest - seemingly killing him.
When the pair are confronted by Horstrogg and the pirates (looking for answers behind the destruction of the Magpie), the Doctor shows them the seeming dead Cyberman - stating his belief that more of the Cybermen were responsible for the pirate ship's destruction and that they must get the crippled freighter engine working again - with Mr Shakka asking the Doctor and Izzy to make the repairs as their engineer was on-board The Magpie when it was blown up. However, the freighter is suddenly grabbed by a mysterious 'energy-leash' that begins to pull the vessel towards the asteroid belt. Splitting up his men, Horstrogg sent one group to scour the vessel for any more Cybermen and two more to keep watch on the Doctor and Izzy while he and Mr Shakka return to the bridge to see what is going on. The Doctor quickly subdues the pirates watching them with an electric charge which knocks them unconscious - but both find to their surprise that Kroton is still alive when he suddenly starts laughing (which confuses the Doctor even more as he had come to believe all Cybermen were emotionless).
After talking gibberish for a while, Kroton manages to introduce himself (complimenting Izzy's hair in the process), with Izzy in turn introducing herself and the Doctor - although the Doctor remains suspicious of Kroton and even thinks the charge might have fried Kroton's logic circuits. Whispering to Izzy, the Doctor states that Kroton's body language and the inflections in his speech are almost human. Despite whispering, however, Kroton hears and comments back - stating that although he cannot smell or taste or even fully feel his fingers, his hearing is excellent. The freighter, meanwhile, is brought to land on a large asteroid with the signs of civilization upon it. Upon landing, Horstrogg dispatches Mr Shakka and his crew to search the asteroid - with Mr Shakka warning his men that he wants answers and so 'not to shoot anything that moves'.
As the Doctor, Izzy and Kroton explore the ship, Kroton forgives the Doctor for what he did - stating that people always jump to conclusions with him. Kroton soon truly shows his uniqueness by commenting on the architecture - referring to it as having been made with a lot of love and pride, as well as calling it both 'rich' and 'beautiful'. This convinces the Doctor that Kroton truly is a unique individual among his kind. When the Doctor asks how Kroton was able to survive the electric charge to his chest unit (which would have been sufficient to kill a Cyberman), Kroton reveals how in the past he helped out the Technosmiths on Baroq VII - with them making 'special adaptions' to his armour as a thank you. He joked about this with the Doctor, stating "When half the galaxy is trying to shoot you on sight, you learn to defend yourself!"
Unfortunately for the trio, they soon find that the room in which the Doctor's TARDIS (a Time Lord machine that can travel in space and time) was located now has a great big hole in the wall - with the TARDIS missing. Now understanding why the freighter was spared from been blown up as the pirate's ship was, the Doctor uses a device he has to lock onto the TARDIS and pinpoint its location as it's their only hope of escaping the pirates. Following the location, they find the TARDIS and the one responsible - who surprisingly turns out to be an old and slightly crazy man. As the trio learn, the device in the man's hand turns out to be a sentient, multifunction energy weapon known as 'the Eraser', who explains that the man (called Tobal Reist) was once a renowned scientist on the planet Trionikus - who created the Eraser as a weapon for future wars. During a test, however, Trionikus was destroyed and its people wiped out. Tobal was the only survivor, with the Eraser creating a gravity web and atmospheric shell for his comfort - although the isolation and guilt have had a bad effect on his psyche, with Tobal remembering little of his past.
The Doctor kindly offers Tobal a ride, but they are interrupted by the arrival of Mr Shakka and the pirates - who have eavesdropped on the conversation and state that they will spare Tobal if he hands over the Eraser. They are instead, however, met with a counter-offer from Kroton as he resumes his battle with the pirates (with Mr Shakka slipping away from the fight). Tobal - while trying to stop the fighting - is shot from behind by Horstrogg, killing him. The Doctor briefly battles Horstrogg for the weapon - managing to steal the power cell for Horstrogg's transmat. Hiding from him, the Doctor is forced at gunpoint by Mr Shakka to give him the power cell (due to an opportunity arising for Mr Shakka to become the new captain - especially since him and the crew are all sick of Horstrogg).
Izzy, meanwhile, overhears Horstrogg talking to the Eraser and learns the Eraser is programmed to obey whoever wields it. Making a not very wise decision, she manages to grab hold of the weapon and orders it to destroy itself. Before Horstrogg can prevent it, the Eraser self destructs. Angered at having lost the chance to own one of the greatest weapons ever made, Horstrogg draws a large blade and prepares to kill Izzy - stating how he will "have her innards for his elevenses". However, Izzy is saved by Kroton - whose mere presence and voice is enough to scare Horstrogg into running, rather then facing off against a Cyberman who has already beaten so many of his men.
As Kroton helps Izzy to her feet and starts to congratulate her for her brave decision, he is interrupted as the entire rock begins to shake violently. As it begins to break apart, the Doctor quickly realizes that the Eraser was creating both the atmospheric shell and the gravity web that was holding the rock together. Now the Eraser has been destroyed, both are collapsing. Kroton and Izzy manage to reunite with the Doctor, but find to their horror that the TARDIS is now adrift and out of reach. Kroton, however, hatches a plan as he magnetizes his staff to his back and tells both the Doctor and Izzy to grab hold. With the gravity failing, Kroton could potentially leap and reach the TARDIS - although if he misses, they will fly past the failing atmospheric shell and be killed. Both Izzy and the Doctor grab hold of the pole, stating they are willing to trust him, and so Kroton makes the leap. The plan works as Kroton grabs hold of the TARDIS before Izzy and the Doctor climb inside.
In the remains of the large asteroid, Horstrogg and Mr Shakka (who have both survived the initial breakup) both get into an argument regarding getting back to the freighter - due to Horstrogg having the transmat and Mr Shakka having the power cell. Neither is willing to trust the other, with the argument continuing as the rocks they are standing on get further and further apart. On board the TARDIS, Kroton is initially lost for words regarding the fact that the ship is bigger on the inside. When the Doctor asks if he finds it "highly illogical", Kroton replies "To hell with logic, this is total lunacy!" With a smile, the Doctor welcomes Kroton aboard the TARDIS as a companion.
The Final AdventureEditGoing on a new adventure with the Doctor and Izzy on his first trip in the TARDIS, the trio end up off course again - arriving on an unknown alien world. Meeting Jynx, an alien who resembles a flying ray, who explains that she is an expositor of the 'Mnemonic Archive of Paradost'. Allowing the three to ride her to the Nexus Gallery where a ceremony is taking place, Jynx explains that Paradost is a 'planetary museum' that stores the life experiences and achievements (including artistic, scientific, religious and emotional as well as personal achievements).
Arriving at the Nexus Gallery, the group watch the arrival of the 'Church of the Glorious Dead' from the planet Dhakan before its leader - Cardinal Morningstar - appears before the crowd. The Cardinal is presented with the final page of the church's holy book (the Odostra), which had been missing but discovered during an archaeological exhibition in the Salius Cluster. During the reception, the Doctor talks to Cardinal Morningstar, who declares the church's belief that everyone in the universe is actually dead and that everyone is in fact only a memory in the mind of the Glory. He further explains that only those who are faithful to the Glory will be reborn, while the 'heretics' will fade from the Glory's memory.
Izzy and Kroton are both offered mnemonic crystals - which are used to recover fading memories and storing new ones. Although Izzy takes one and has a happy moment remembering a past achievement with her old friend Max Edison, Kroton abruptly refuses to take one and decides to leave for a while. Unbeknown to Kroton, he has been watched by both Cardinal Morningstar - who declares that Kroton has no part in the 'divine plan' as he is neither alive nor dead. As such, he declares that the cyberman must be purged - telling one of his bishops to 'summon the chosen'.
Outside, Kroton meets four more Dhakans - who appear to commit suicide by turning a device on their chest that causes them to burst into flames. However, they suddenly reappear as burning life forms (the chosen) who declare Kroton a heretic and attack him - managing to cut through his armour with their bladed arms. With his own attacks useless against the creatures - Kroton makes what he declares as the stupidest decision he has ever made and leaps from the bridge. Thankfully, he is caught by another expositor called Tyll - whom Kroton declares to head for the Nexus Gallery as his auto-repair systems kick in. Arriving there, he manages to pick up the Doctor (who had recently sent Jynx and Izzy to the reading room to try and learn more about Dhakan).
Trying to flee from the creatures pursuing them, the sky suddenly becomes full of them as Cardinal Morningstar (back on-board the Dhakan ship) declares from the Odostra's last page that Paradost must burn in preparation for the 'regeneration of the faithful'. One of the creatures kills Tyll, with the Doctor and Kroton leaping clear onto the rooftop where the TARDIS is located. As he tries to open the door, however, the Doctor and Kroton watch in horror as the TARDIS dematerializes - leaving them stranded. As the Doctor tries to protect Kroton, the creatures are ordered to surrender by the Paradost Militia. However, the creatures retaliate and destroy the militia - with the Doctor and Kroton managing to flee with Jynx (who Izzy sent to search for them).
As they watch, the creatures and Dhakanians begin the jihad against Paradost - attacking everything. This proves a massive shock to Jynx, who states that she has never seen anything like what is happening and that Dhakan has never attacked another world. She also declares that an alliance of over a thousand worlds have already sent a fleet to defeat the Dhakanians. However, Cardinal Morningstar has already planned for it and orders the creatures to form a barrier around Paradost to stopped the allied fleet from entering. Arriving at the reading room, Kroton manages to knock out and capture one of the bishops - with the Doctor analyzing the device on his chest (referred to as a 'soul key') and states it's a warp-subtraction circuitry device - powered by the body's internal combustion - that activates a multidimensional portal (meaning the creatures are from a different dimension and need a human to give up their life to appear in this one).
Declaring to know what the creatures are, the bishop tells the Doctor that they are called the 'Ash Wraiths' - whom he refers to as the Glory's archangels. The Doctor manages to come up with a plan to stop the Ash Wraiths quickly, which he refers to Izzy as been as simple as 'walking on water'. Before he can explain, however, the Doctor mysteriously disappears. In the weeks that follow, Kroton and Izzy become fugitives, trying to survive with help from Jynx and moving through hyper-transit tunnels with refugees from all over the planet. Despite the Dhakanians trying to shut the tunnels down, there were thousands to use. Although Izzy and Kroton tried to help as many refugees as possible, they were betrayed and had to fight their way out. Izzy and Jynx both later got angry about it, Kroton calmed her down after reminding her that death can twist anyone's thinking and to try to forgive those who betrayed them.
With the ships outside unable to get in to help, the Doctor missing and the Paradost Militia slaughtered after only a few days, the Church of the Glorious Dead destroyed entire cities across the planet, performed executions first for the alien ambassadors (for the "crime of unbelief") and then performing mass trials on the Paradostrians. They also burned the memory hives on the planet in rituals - declaring that only the memories of the Glory were real. Talking to Kroton one night from their hiding place, Izzy asks Kroton why he didn't take the mnemonic crystal on the night they arrived. Kroton truthfully replies that he does occasionally have flashes of his past before he was a cyberman and, while admitting he would like to remember, he feels that remembering would be the worst kind of torture - adding to the fact that he can never reclaim what he's lost. Izzy sympathizes - adding that when she was a few hours old, her parents abandoned her at a bus stop - with her been told the truth by her foster-parents when she was eight years old. Although Izzy admits she would like to find out the truth about her real parents - with the possibility that the Doctor could find out easily enough - she feels that it would be too sad. Kroton agrees, believing that some truths should remain buried.
Remembering what the Doctor said about stopping the Dhakanians been as easy as "walking on water", Izzy comes up with a plan. With the help of Kroton, Izzy and Jynx break into a base where an 'environmental impulse web' is located (which is used to control the weather). After Kroton deals with the Dhakanians outside and inside, Izzy and Jynx convince the scientists inside to brew up a blizzard - in the hopes it will bring down the Ash Wraiths. Outside, Kroton is brought down temporarily by a trio of Ash Wraiths - but the blizzard started up successfully starts to bring them down. In turn, the barrier the Ash Wraiths put up around Paradost breaks up and finally, the alliance of worlds manage to enter and begin to battle the Dhakanians. In order to prevent the process been reversed, Izzy and the scientists destroy the machinery. Unfortunately, with Kroton down and Jynx not able to fight, Izzy is beaten down by a group of the Church's bishops before Cardinal Morningstar appears to kill Izzy. However, he instead has used a Tissue Compression Eliminator to shrink Izzy down before capturing her. The Dhakans soon begin to lose the fight as they are heavily outnumbered - although the Cardinal declares that their work is done and for their forces to return to Dhakan. Before they leave, however, Kroton (with help from Jynx) manages to get aboard the Cardinal's flagship - with Jynx leaving quickly to avoid been caught in the back-blast and wishing Kroton the best of luck. On-board the ship, Kroton quietly declares to himself that he will avenge Izzy's death (unaware that she's still alive).
Inside the Flagship, Izzy is shocked to learn that Cardinal Morningstar is actually Sato Katsura - a samurai whom Izzy befriended on a previous adventure, during which the Doctor unintentionally made him immortal and immune to pain - due to the nano-drones placed inside Sato's body to heal him malfunctioning. Sato explains that due to his inability to die, he felt he had lost his honor and left Japan in disgrace. He crossed to the Caribbean and became a pirate - but soon became bored of fighting battles he could never lose and turned himself into the Inquisition. They declared him a demon and tried to kill him through holy torture, but were never able to due to the nano-drones. Admitting defeat later, the Inquisition locked him up in a cell in Saragossa and tried to forget him - leaving him there for 50 years. When Sato was later visited and released by an old man in a priest's robe, Sato tried to kill the man. However, the man suddenly shrunk Sato down and explained that the injustices he had suffered had helped prepare him for a "great and holy task", adding for Sato to obey him - after which Sato's honor will be restored. Sato accepted - believing the man's words.
Elsewhere, the Doctor finds himself at the center of the Omniversal Spectrum (the totality of all existence) - having been brought there by a being known as Esterath. The center of the spectrum is the Glory, which Esterath explains is a machine to which "all of reality turns". However, it needs a living force to direct it, and the Glory itself is now dying - requiring a new 'host'. Esterath states he is the current host but is now dying as he is linked to the Glory. Explaining he is also the one who must gather two adversaries who are alike yet polar opposites to battle one another in order to become the new 'inheritor'. Due to the time remaining before the Glory stops, Esterath takes the Doctor on Primus (Esterath's world-ship) to meet his adversary - who he states is on Dhakan. Arriving and teleporting the Doctor to the planet's surface, the Doctor soon discovers to his horror - after seeing the church of St. Paul - that Dhakan is actually Earth. The TARDIS materialized moments later, with an old man who the Doctor saw on a previous adventure appearing from inside - the same man who appointed the 'great and holy task' to Sato. The man reveals himself as been the Doctor's old enemy, the Master.
The Master explains what happened following his and the Doctor's last battle in San Francisco, with the Master been devoured by the Eye of Harmony inside the Doctor's TARDIS. Esterath came across the dying essence of the Master after his remains had been spat out into the Time/Space vortex. Telling Esterath everything, Esterath showed the Master the Omniversal Spectrum before later putting him in the body of a recently deceased vagrant in Brixton, London. The Master also reveals that when the TARDIS swallowed him through the Eye of Harmony, part of his essence had infected the TARDIS and allowed the Master to form a symbiosis with the TARDIS - controlling it. He used this to deliberately change the TARDIS's destination on several occasions. He also reminds the Doctor of Sato Katsura and explains how the Master used him to conquer Earth in a holy war that lasted decades and create Dhakan in the 19th Century. By the 20th Century, Dhakan achieved interstellar travel and began to spread their doctrine to other worlds, with the Master returning to give Sato his blessing and renamed him 'Cardinal Morningstar'.
Finally, the Master explains about the Ash Wraiths and that only the final page of the Odostra (a book in which the Master wrote in an afternoon, fictionalizing the Glory as a god) is correct in which two adversaries will battle to become the new 'inheritor' of the Glory. Esterath soon appears - explaining that the duel between the Doctor and the Master will take place in the Omniversal Spectrum and both will have equal powers - transporting both of them there to fight. On Dhakan, meanwhile, Sato addresses his people and declares that soon all will be reborn and the heretics will soon only be a memory. His speech is interrupted, however, by an extremely angry Kroton - who emerges from one of the ships and challenges Sato to a battle. Sato agrees to the battle and orders his men not to intervene.
After putting aside some of his belongings (which includes a captive Izzy), Sato begins his battle with Kroton - with their battle proceeding to a high but narrow bridge. Both prove to be solid opponents for the other, with Sato's warrior knowledge and both his inability to feel pain or get tired matching with Kroton's superior strength - which is proven as Kroton succeeds in shattering Sato's armour. Although Sato warns Kroton that he doesn't understand what 'fires rage inside him', Kroton declares Sato is wrong as he and Izzy talked a lot about him during the mass killing on Paradost - adding that Izzy actually admired Sato. Kroton then states "I don't know what twisted you into a man who could murder millions - including a girl who considered you her friend - and I don't really care...Just understand this: when the last blow connects, it'll be for Izzy!"
Meanwhile in the Omniversal Spectrum, the Doctor and the Master begin their battle. The Master initially holds the advantage due to his experience, although the Doctor soon fights back and manages to hold his own against his evil adversary. Throughout the battle, the Master and Doctor exchange verbal blows as well as physical, with the Master trying to break through the Doctor's defenses by claiming how similar they are - although the Doctor retaliates every time. However, the Master finally appears to breach the Doctor's defenses when he states that the Glory is the answer to every question (drawing on the Doctor's constant exploring and seeking of both knowledge and adventure) and demanding that that Doctor admit that he desires to become the inheritor as much as the Master does. The Doctor does admit he wants it, but that means he deserves it no more then the Master. However, the Master uses the opportunity to impale the Doctor with his blade - winning the fight and gloating over his victory, as well as inhibiting the Doctor's energy to stop him from regenerating into a new body. Bringing the Doctor with him, the Master begins his return to Dhakan to prepare for his 'impending Godhood'.
Back on Dhakan and despite his attempts to defeat his opponent, Kroton's attacks are rendered useless due to Sato's inability to feel pain. Unbeknown to both of them, Izzy had managed to escape from the glass 'test-tube' that Sato had put her inside and also - upon seeing the device Sato used to shrink her - returned to normal size after jumping on the correct switch to reverse the shrinking process. Sato finally gains an advantage over Kroton and tackles Kroton off the narrow bridge - both adversaries plummeting before crashing through the roof of the St. Paul's cathedral (which Sato left standing as a warning to his people that they would 'remain dead if they failed in the eyes of the Glory again). Sato proceeds to badly beat Kroton - rendering the cyberman unable to continue the battle. Admitting that Kroton fought well and that Sato could only wish that Kroton would join him in the 'hour of rebirth' - he states that 'both warriors' know it won't happen.
Before he can kill Kroton, however, Izzy bursts in. Confronting Sato over his actions and that fact she feels he became what he has become due to just not feeling anymore, Izzy declares to him that it's important to feel - even if that feeling is pain. Giving him the Mnemonic crystal she received from Paradost, Sato experiences all the pain that Izzy saw and felt during the three weeks that the Church of the Glorious Dead spent destroying Paradost and slaughtering the many species. Upon seeing this, Sato drops down in anguish and despair as he realizes he has been wrong the whole time and that everyone is alive.
Kroton congratulates Izzy, calling her a genius and telling her to thank any God she cares to pick. Izzy then recovers the crystal and holds it out to Kroton - telling him it is his turn to take the crystal now; saying that while some truths stay buried, others don't. Esterath appears and agrees - telling Kroton to do as Izzy says.
Taking the crystal from Izzy, Kroton finally remembers his past life before he was turned into a Cyberman as his memories come flooding back. Among what he now remembers, he sees he had a happy life with his wife Shallia - whom he says had such a gentle laugh - as well as having both a son and a daughter. All of whom were lost when the Cybermen invaded. Although Kroton states it hurts that he can finally see all that he lost, he admits that seeing what he had was very sweet too. He thanks Izzy, but their happier moment is cut short by the arrival of the Master and the dying Doctor. The Glory soon appears, with the Master intending to enter it and become the new inheritor of the device.
However, the Master is shocked when the Glory rejects him. Esterath quickly explains his realization that he was never the gatherer and that the Master and the Doctor weren't the adversaries. Instead, he points out that Izzy was the true gatherer and that the two adversaries were Kroton and Sato - with Kroton been the winner as he has held onto hope while Sato has fallen into despair. The Master - angry and in denial - tries to destroy Kroton, but Esterath removes his power and his existence inside the TARDIS. Esterath instructs Kroton that he must act now for the sake of everything, to which Kroton agrees. Hugging Izzy, he says his goodbyes to her and the Doctor - who again apologizes for shoving the high voltage cable into Kroton's chest during their first meeting. Having said his goodbyes, Kroton enters the Glory. Upon entering, Kroton uses his new powers to restore Earth back to normal, heal the Doctor, banish the Master and give Sato what he always wanted - an honorable death.
Following the events, Esterath bid the Doctor and Izzy farewell - stating his journey had ended but that theirs had barely begun. When Izzy questioned the Doctor about if they would have a 'guardian angel' of sorts looking after them now that Kroton had become the Glory's new inheritor, the Doctor replied that he doubted it as Kroton would have a lot more to deal with then their little adventures. The two then headed off to enjoy the night.
