Ultimatrix

The Ultimate Omnimatrix (often referred to as the Ultimatrix) was the device that Ultimate Alien revolved around. Ben uses it to replace the Omnitrix, which he destroyed in a Past Battle with Vilgax. Azmuth isn't impressed of Albedo's work on the Ultimatrix. He said it was "Pathetic workmanship" and was frustrated with the evolutionary feature.

After giving Ben the Omnitrix, Azmuth deactivated the Ultimatrix off-screen.

Backstory
Originally created by Azmuth, the Ultimatrix's power core was unstable and incomplete so he put the device in high security storage. Albedo stole the Ultimatrix and was able to stabilize the core, as well as "surpassing" the original Prototype by adding the Evolutionary function. Unfortunately 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 Albedo 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 force Vilgax 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 as Jetray managed to escape.

Description
The Ultimatrix, unlike the Omnitrix, didn'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 was identical to the original dial, with the intergalactic peace sign that changes color to reflect what mode the Ultimatrix was in.

Features

 * The Ultimatrix could access the Codon Stream's database to show which transformations have been activated over time.
 * The Ultimatrix functioned as a wireless receiver for the Codon Stream.
 * The Ultimatrix was linked to the voice and DNA of Ben and responds to voice commands as the Omnitrix did.
 * The Ultimatrix had the ability to evolve aliens into their Ultimate Form, granting them new powers and new abilities that are more powerful. This was activated by pressing the Ultimatrix symbol as an alien, causing four gray spikes to grow.
 * According to the Cosmic Destruction website and Dwayne, the evolution feature worked by placing the selected species in a simulation, right down to the DNA, of the worst possible future for an extended period of time, about a million years or so, in what is described as a "worst case scenario"; the actual DNA is then simply modified to match the new DNA. This survival of the fittest routine explains why the evolutions are more combat-centered than their normal forms.
 * The Ultimatrix served as a communicator when transformed and not transformed, like the Omnitrix.
 * According to Dwayne, the Ultimatrix did have a Master Control.
 * The Ultimatrix always went into Capture Mode when there is a sapient species' DNA that isn't in the Codon Stream within its proximity.
 * There were several ways of removing the Ultimatrix:
 * The Ultimatrix had a voice Command, just like the Omnitrix.
 * Pressing the black button next to the dial.
 * Ben was also able to remove the Ultimatrix from his Plant Clone by grabbing it at the same time the clone attempted to turn into an alien, so instead of the Clone turning into Swampfire, Ben did.
 * The Ultimatrix had A.I (Artificial Intelligence).
 * The Ultimatrix could add extras to alien forms (Goop's anti-gravity disk, NRG's suit, etc.) to make the forms more safe/usable.
 * The Ultimatrix could change the clothing that the aliens wear, Ben doesn't quite know how the feature worked. It is shown that returning aliens had unique clothing to them (e.g. Four Arms).
 * According to Dwayne, Albedo individually applied this function to each of the aliens.
 * It is possible the Ultimatrix could adapt the user's clothing to fit the alien, Eugene said it was possible this setting would of be used again.
 * According to Dwayne, the Ultimatrix did not possess the ability to revive species stored on Primus, due to it not being added by Azmuth at the stage of development it was in and Albedo didn't add it.
 * According to Eunice, the Ultimatrix did not possess the ability to restore DNA.
 * It seemed that the Ultimatrix can't detect outer dimensional creatures.
 * The Ultimatrix could detect other Matrix cores like Eunice.
 * The Ultimatrix automatically reverted the user back into their normal form when they get sufficiently hurt or knocked out.

Unseen Features

 * A Primacron Evolution Scanner.
 * Cerebrocrustation designed Devo-Lution chip.
 * Quantum destruct mechanism.
 * DNA fail-safe cloning card.

Aliens
The Ultimatrix had a total of at least 1,000,910 aliens via the Codon Stream, 63 unlocked aliens and 54 named aliens. Ben has transformed into 35 out of 43 listed.

Note: See the Codon Stream's Species DNA for a more detailed number of aliens Ben can possibly turn into.

If the "When and How unlocked" field is blank, then that means that the alien was already synced to the Omnitrix before its destruction.

Unlocked Aliens
These are all the known aliens the Ultimatrix has ever had unlocked.

Other Known Aliens
These are the aliens that have been named and confirmed to exist. They were never shown to be unlocked and transformed into in Ultimate Alien.

Trivia

 * According to Matt Wayne, the aliens were not according to the user's age, they are the "prime specimen of the respective species".
 * According to Matt Wayne, Ben scaned aliens off-screen and reordered his list afterwards.
 * According to Matt Wayne, Ben had much more aliens than we think he has.
 * According to Matt Wayne, Ben manipulated the Ultimatrix to switch forms or go Ultimate.
 * According to Dwayne, the Ultimatrix was showing signs of it not being completed properly.
 * According to Dwayne, the Ultimatrix was less powerful than the prototype Omnitrix.
 * According to Dwayne, the Ultimatrix was Level 20 technology.
 * According to Dwayne, the Ultimatrix was 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 scaned 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 were 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.
 * 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 related to Ben's pink eyes when he transformed from an ultimate form in Fame.
 * Azmuth could keep an eye on Ben and his activities via the Ultimatrix.
 * The Ultimatrix is misspelled "Ultamatrix" on the Cartoon Network site.
 * In Cartoon Network's "Top 10 Things To Wear On Your Wrist" the Ultimatrix is #5.
 * According to Derrick Wyatt, Azmuth deactivated the Ultimatrix after The Ultimate Enemy: Part 2.
 * The reason he deactivates the Ultimatrix was because Azmuth considered it inferior junk and it was too dangerous to keep.
