Abslom Daak was a dangerous and psychopathic criminal from the mid 26th century, who was sentenced to be exiled as a 'Dalek Killer' for his crimes. After the Daleks took the life of Taiyan (a woman and princess from the planet Mazam who he had fallen in love with), he began a crazed vendetta to kill every Dalek in the galaxy. The Daleks themselves even recognized him as their 'other greatest enemy' after the Doctor.
JUDGE: "Abslom Daak... you have been been found guilty on 23 charges of murder, pillage, piracy, massacre and other crimes too horrible to bring to the public attention. There are two choices: death by vaporization or exile D-K!!"
DAAK: "Vaporization doesn't hurt... I'll take Dee-Kay!!"
JUDGE: "You know what this entails?"
JUDGE: "Then may your god have mercy on your soul. Take him away!"
- Daak is sentenced to be exiled as a Dalek Killer.
In the mid-26th century, Daak was convicted of "twenty-three charges of murder, pillage, piracy, massacre and other crimes too horrible to bring to the public attention". At the close of his trial, he was given the choice between vaporization or exile as a Dalek Killer. He chose the latter. Out of a selection of many weapons, his choice was (and continued to be) a chainsword. Daak was transported to the primitive planet Mazam in the Dalek Empire, the Humanoid rulers of which appeased the Daleks occupying their world. He destroyed a Dalek task force single-handedly and rescued the Princess Taiyin, with whom he fell in love. She decided to strike out against her masters. She was killed by a Dalek survivor that Daak had overlooked, leaving Daak grief-stricken and vowing to eliminate every Dalek in the galaxy.
With Taiyin's body alongside him in cryogenic suspension (he hoped that medical technology might one day revive her) Daak joined with the Draconian Prince Salander, his old human friend Vol Mercurius and an Ice Warrior, Harma, who came to travel the galaxy in a small ship known as the Kill-Wagon. He continued to kill Daleks, often armed only with an energy pistol and his personal chainsword. Fond of the bottle, Daak remained a tough-talking ruffian - almost psychotically eager for battle.
He met the Seventh Doctor (who had heard of Daak) on the planet Hell after the Kill-Wagon had crashed there while while investigating Dalek activity. He thought his fellow Star Tigers had died in the crash. They found the Daleks mining a deadly gas, helkogen, out of the planet, taking it up to an orbital Dalek Death Wheel to build a genocide machine. Daak sacrificed himself by flying a captured Dalek hovercraft into the Wheel's reactor core, destroying the Wheel and the Dalek's plans.
Daak was plucked out of time just before his moment of death by a Dalek faction led by the Supreme Dalek and used to locate and lead the Seventh Doctor into a trap. Eventually he discovered that he had been tricked, and aided the Doctor, the Doctor's companion Bernice ("Benny") Summerfield (another native of the 26th century left without parents by the Daleks) and his old allies (who he learned had survived the crash) in defeating the Daleks once more. On Skaro - after Davros and the daleks loyal to him achieved victory and destroyed the Golden Emperor Dalek, Daak revealed that the Doctor had freed him and the others ages ago and attacked the "wheelchair" part of Davros with his chainsword, crippling him. After been pulled into the TARDIS to escape the city's self destruction, the group departed Skaro. With help from Benny, Daak got over his fixation with Taiyin, but then nursed a crush on Bernice.
Daak received an invitation to come to Cheldon Bonniface for Bernice Summerfield's wedding to Jason Kane. However - and perhaps fortunately for all concerned - he turned it down, stating he still hadn't killed every Dalek in the galaxy.
- On the planet Phaester Osiris, Daak tried, without luck, to come onto Sarah Jane Smith while she visited that world with the Fourth Doctor. (Where this fits into Daak's personal history remains unknown. However, since his crew, the Star Tigers, did not put in an appearance, this might have happened before he met them).
- At some point in his life, Abslom Daak visited Maruthea and took part in the birthday party of the Dæmon known as Bonjaxx. He was among several individuals who the Seventh Doctor recognized when he too visited the party.
- In the Doctor Who television episode Time Heist, Psi (an augmented human who was working with the Twelth Doctor) is scanning quickly through all the posters of wanted individuals. One of the individuals is Abslom Daak (although the scene has to watched frame-by-frame to see him due to its speed). This appearance is likely just an 'Easter Egg' by the BBC.
- At least one of Daak's ancestors was also a criminal and, in 2009, was found guilty by Intersol for crimes against New Devonia.
- A cryogenically frozen clone of Abslom Daak was revived by Ace in 2573. Ace thought of him as the only Daak and, with Benny, tried to stop him from dying because, thinking him the real, original Daak and not a clone, they knew that Daak would die on Hell. He was killed while saving Ace from the gestalt intelligence named Pool.
- An unnamed Daak made a short appearance outside of the Doctor Who universe in "Oasis" written and drawn by the original Daak team, Steve Moore and Steve Dillon, which originally appeared in the British comics magazine Warrior.
In the story, featuring interstellar mercenary Axel Pressbutton and his traveling companion, Mysta Mystralis/Laser Eraser, shows an unnamed Daak tries to hit on Axel's Mysta. Not happy with his interest, she easily bests him - although this only makes Daak like her even more, to which Axel jokes that Daak should see her when she's angry - before asking the bartender to give Daak a drink. (Steve and Alan Moore, had, incidentally, specifically conceived of the Warrior universe as a parallel to the Doctor Who Universe and made the Chronarchs, parallel versions to the Time Lords of part of that universe, though they never put in an appearance.)
- A variant of Daak's statement "Whatcha gonna do now, big shot? Suck me to death?" appears in the Doctor Who TV Episode "Dalek" - with the line been spoke by Henry Van Statten's leading field researcher and technican Simmons (a sadistic individual who tortured the dalek in the episode). However unlike the helpless Dalek in the comic strip, the Dalek proceeds to do just that with his manipulator arm - suffocating Simmons and crushing his skull with the manipulator arm.
"I'm gonna kill every last stinking Dalek in the galaxy!" is similar to the Ninth Doctor's promise at the closing of "Bad Wolf", with the Doctor saying he's going to save Rose Tyler, save the Earth and then - just to finish off - wipe every last stinking Dalek out of the sky.
- Marvel tried three times to bring Abslom out of the Doctor Who universe and give him his own unrelated strip. A similar character from their Blake's 7 comic, Valkac, was to be brought into the Star Tigers (with Harma and Salander bumped off) who would then be spun off out of the Doctor Who universe; this attempt was ended by Steve Moore quitting the comic. In 1990, Marvel UK tried to start a non-Who Daak miniseries by Dan Abnett. After that, Moore wrote a proposal for a ten-issue miniseries After Daak that would attempt the same thing, with a less heavy four-issue miniseries intended to run before it; this fizzled out, partly because Marvel US wouldn't allow 10-issue minis and because they viewed Doctor Who as a dead brand. The pitch for After Daak was put online at Altered Vistas.
