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 battle with Vilgax. The Ultimatrix was removed by Azmuth in the The Final Battle: Part 2 and replaced by the true Omnitrix.

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 prototype Omnitrix by adding the evolutionary function. Unfortunately for him, Ben's DNA was still the default for the Omnitrix and the Ultimatrix 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 as Ultimate Negative Humungousaur easily defeated Ben as Humungousaur, Vilgax threatened Gwen and Kevin's lives in order to force Ben to give up the Omnitrix. Afterwards, Vilgax betrayed Albedo 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 suffered the consequences. Ben released Albedo and forced him to give him the Ultimatrix via the same threat. Ben used Ultimate Swampfire to battle Vilgax and used Jetray to later escape.

Ben continued to use it until he defeated Vilgax with Diagon's powers, Azmuth came to take Ascalon as well as the Ultimatrix and gave the new Omnitrix to the worthy wielder.

Description
The Ultimatrix, unlike the Omnitrix, didn't resemble a wristwatch, looking more like a gauntlet. 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.

Modes
Active Mode is the Ultimatrix's default mode. Normally Active Mode is active when the Ultimatrix can be used and nothing is wrong. Recharge Mode's main purpose is to keep the Ultimatrix from damaging the user. Recharge Mode is activated when the Ultimatrix runs out of time. Recharge Mode is deactivated automatically, once a certain period of time has passed. According to Dwayne, using Ultimate Forms will make the Ultimatrix go into Recharge Mode sooner than using non-Ultimate aliens. When DNA not in the Codon Stream is near the Ultimatrix, it closes its main features until the DNA is scanned. When a new DNA sample is acquired, the Ultimatrix sometimes shows a picture of almost every alien unlocked, plus the new one. When a new DNA is sensed, the Ultimatrix either pops out and shoots out a yellow ray from the black and yellow part or doesn't pop out but circles and then reveals a hole which shoots out the yellow ray. When in alien form, the Ultimatrix shoots out a yellow ray from the dial. If the DNA is already in the Codon Stream, the Ultimatrix will have to be set to Scan Mode manually and the alien will just be unlocked and available for use. The Ultimatrix deactivates, charges, and re-activates. It can turn off/on some features. Reset Mode can be activated by Voice Command or by pressing and holding the Ultimatrix symbol as an alien for 2 seconds. The Ultimatrix shuts down, making it of no use. This mode first appeared in The Ultimate Sacrifice. Radiation Mode is activated when radiation is detected. The Ultimatrix will beep and flash red. Radiation Mode is activated whenever high levels of radiation are detected. Radiation Mode can be turned off by turning the Ultimatrix symbol to the quarter past position as an alien, or when radiation isn't detected anymore. When in Self-Destruct Mode, the Ultimatrix counts down until it explodes. Self-Destruct Mode functions as a last resort should the Ultimatrix fall into the wrong hands. Self-Destruct Mode can be activated and deactivated by Voice Command.

Features

 * According to Dwayne McDuffie:
 * The Ultimatrix did have a Master Control.
 * 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.
 * 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, 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 other Omnitrixes.
 * 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 that removes it, just like the Omnitrix.
 * Pressing the black button next to the dial makes the Ultimatrix larger in size, so it can be slipped off.
 * 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.) in order 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, however, it wasn't.
 * 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.
 * The Ultimatrix had the ability to transform between alien forms without touching the Ultimatrix symbol, which is evident in episodes like Where the Magic Happens, where Ben was able to change from Jetray to Cannonbolt, without touching the symbol.

Aliens
The Ultimatrix had a total of at least 1,000,910 aliens via the Codon Stream, 63 unlocked aliens and 47 named aliens (Ultimate Forms Not Included). Ben has transformed into 35 out of 44 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".
 * Ben scanned aliens off-screen and reordered his list afterwards.
 * Ben had much more aliens than we thought he did.
 * Ben manipulated the Ultimatrix to switch forms or go Ultimate.
 * Ben had scanned aliens that are not in the Ultimatrix database.
 * However, he didn't scan them at every chance he got.
 * According to Dwayne McDuffie:
 * Tthe Ultimatrix was showing signs of it not being completed properly.
 * The Ultimatrix was less powerful than the prototype Omnitrix likely due to the fact that it did not have the ability to repair genetic damage.
 * The Ultimatrix was Level 20 technology.
 * The Ultimatrix was more complicated to use fully than the Omnitrix.
 * Albedo installed more features in the Ultimatrix than we know.
 * According to Derrick J. Wyatt:
 * There were technical glitches in the prototype Omnitrix and Ultimatrix that limited the positioning of the Omnitrix during transformations.
 * This actually caused interference with the transformations such as power glitches.
 * Azmuth reformatted and corrected these errors in the Omnitrix.
 * Azmuth destroyed the Ultimatrix off-screen after The Ultimate Enemy: Part 2.
 * 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 was misspelled "Ultamatrix" on the Cartoon Network site.
 * In Cartoon Network's "Top 10 Things To Wear On Your Wrist" the Ultimatrix is #5.
