Azmuth isn't impressed with Albedo's work on the Ultimatrix. He said it was "pathetic workmanship" and was frustrated with the evolutionary feature.
In The Ultimate Sacrifice, Azmuth fixes all glitches in the Ultimatrix.
Originally created by Azmuth, the Ultimatrix's power core was unstable and incomplete so he put the device in high seccurity storage. Albedo stole the Ultimatrix and was able to stabilize the core. Unfortunatley for him Ben's DNA was still the default for the Omnitrix and was still linked to the same database, so Albedo only had access to Ben's current aliens, which excluded Grey Matter. Allying himself with Vilgax, he agreed to help him so he could turn himself back to normal, while Vilgax could have the earth. After Negative Ultimate Humungousaur easily defeated Ben as Humungousaur, Vilgax threatened Gwen and Kevin's lives in order to force Humungousaur to give up the Omnitrix. Afterwards, Vilgax betrayed Negative Ultimate Humungousaur by using the Omnitrix to defeat him by turning his army of bioids into thousands of Humungousaurs. Later, Ben activated the Omnitrix's self-destruct mechanism to remove it but Vilgax refused, thinking he was bluffing and later suffering the consequences. Ben released Albedo and forced him to give him the Ultimatrix via the same method. Ultimate Swampfire battled Vilgax and Jetray managed to escape.
The Ultimatrix, unlike the Omnitrix, doesn't resemble a wristwatch. The central component, the selection interface remains the same, while the watch band was replaced by a gauntlet-like band extending up to almost half of the wearer's arm (since the band's ability to morph its shape wasn't placed into it). When Albedo used it, the Ultimatrix had a red color scheme. After Ben took the Ultimatrix from Albedo, the Ultimatrix became green. This shows that the user can change the color scheme. The selection interface is identical to the original dial, with the intergalactic peace sign that changes color to reflect what Ultimatrix mode the Ultimatrix is in.
- The Ultimatrix can access the Codon Stream's database to show which transformations have been activated over time.
- The Ultimatrix functions as a wireless receiver for the Codon Stream. The Ultimatrix rewrites the user's DNA on a quantum level and creates mass energy (and vice versa) as needed.
- The Ultimatrix is linked to the voice and DNA of Ben and responds to voice commands as the Omnitrix did.
- It seems that Ben has not been able to figure out certain alien's powers (Eatle and Shocksquatch) before seeing their species, but yet Ben was able to instantly know his Alien Force Original's powers from the start.
- According to Matt Wayne, the aliens are not according to the user's age, they are the "prime specimen of the respective species".
- According to Ben, as of The Flame Keeper's Circle, the Ultimatrix has 63 unlocked aliens.
- According to Matt Wayne, Ben scans aliens off-screen and reorders his list afterwards.
- According to Matt Wayne, Ben has much more aliens than we think he has.
- According to Matt Wayne, Ben manipulates the Ultimatrix to switch forms or go Ultimate but he will occasionally use other methods.
- According to Dwayne, the Ultimatrix already shows signs of it not being completed properly.
- According to Dwayne, the Ultimatrix is "not more powerful, less powerful" than the Omnitrix.
- According to Dwayne, the Ultimatrix is Level 20 technology.
- According to Dwayne, the Ultimatrix is more complicated to use fully than the Omnitrix.
- According to Dwayne, Albedo installed more features in the Ultimatrix than we know.
- According to Matt Wayne, Ben scans aliens not in the Ultimatrix database. However, he doesn't scan them at every chance he gets
- According to the Ultimatrix in Prisoner Number 775 is Missing, there are 5 playlists in the Ultimatrix, this originally hinted that there were 40-50 unlocked aliens since aliens are kept in sets of 10. However, according to Dwayne, Ben can put more than 10 aliens in one playlist.
- Ben often re-arranges the order of aliens in his playlist off-screen. This is to allow him quicker access to the aliens he believes he'll need to use in an expected fight.
- It's confirmed Ben scanned Manny to unlock Four Arms.
- Because the Ultimatrix isn't properly complete, it often glitches.
- Azmuth's exact plans for the Ultimatrix are currently unknown. However, the evolution of the aliens were not a part of them; according to Dwayne, Albedo jury rigged the unstable core of the Ultimatrix and cobbled it together, creating by himself the function of "evolving" aliens.
- Azmuth did not want to have the Ultimates in the Ultimatrix because they would be used for violence. He even commented on the evolutionary feature, stating it was "begging for trouble". Dwayne said that Azmuth's dislike for the evolutionary function is partly related to Ben's pink eyes when he transformed from an ultimate form in Fame.
- When Ben scanned P'andor, P'andor didn't wear his suit, but when Ben turns into him, he wears it. That is because the Ultimatrix A.I made the suit or he would be too dangerous to use, especially to those who are vulnerable to its radiation.
- Azmuth can keep an eye on Ben and his activities via the Ultimatrix.
- As seen in the episode Video Games, Ben mentions that the Ultimatrix is almost about to time out, and the Ultimatrix logo on the chest of Big Chill began to blink. Still, the Ultimatrix had enough power for one more transformation before it locked.
- There are two ways for going Ultimate, as seen in The Final Battle and Too Hot To Handle: one is by turning the metal part of the dial which makes the face pop out and then pressing on it; the other is by again turning the metal part of the dial, but this time the face turns also, and then tap on it. In recent episodes, Ben has adjusted the settings so he merely needs to press the Ultimatrix symbol much like how he uses it to switch between forms.
- The Ultimatrix is misspelled "Ultamatrix" on the Cartoon Network site.
- Unlike the Omnitrix, the Ultimatrix always puts Ben's normal clothes on him when he wears something else. This is because of a problem in the setting that deals with Ben's clothing. The reason for this problem is because the preferences are set incorrectly. Any of the clothes that he wore over his normal clothes are still stored within the Ultimatrix until needed. However, he learned how to change this setting, as shown in Basic Training.
- In Cartoon Network's "Top 10 Things To Wear On Your Wrist" the Ultimatrix is #5.
- The Ultimatrix lacks many of the features to double as a Plumber's badge like the Omnitrix, so Ben instead now carries a regular Plumber's badge when needing to prove his authentication as a Plumber or use it.
- As revealed in The Ultimate Sacrifice, the Ultimatrix makes individuals of the Ultimates and gives them their own minds and wills. Azmuth fixed this feature so Ben's Ultimates will just be reflections of him.
