The Omnitrix refers to a series of devices created by Azmuth that allow the user to transform into over one million different transformations in the Alien Universe.

Assault Omnitrix[]

Alphaline Omnitrix[]

When the Alphaline Omnitrix is worn, the user is able to transform into any beings in the active playlists.



The Omnitrix was first conceptualized by Azmuth after the Unitrix as a single device that could be used to let the user become any other alien. Though Azmuth has provided a number of different excuses for its creation, in Plight of Pinocchio, it boiled down to it being an attempt to win back the affection of his former flame Zennith by marrying magic and technology into a single device.


Before the device could be used, DNA samples needed to be acquired. At some point, Azmuth decided he would use DNA from the peak member of each species as declared by each species themselves. For example, this included selecting Tux as the Chimera Sui Generis sample, as opposed to Vilgax. The first Unitrix, Cassie, was involved in the sampling process.


Albedo and Myaxx were involved in the development of the Omnitrix. At some point, Azmuth's reclusiveness scared off Myaxx, and Albedo's repeated attempts to make the Omnitrix into something it's not - including having an evolutionary function - led him to depart the project.

During development, other beings Azmuth met along the way would come to be known the Omnitrix Force, protectors of the device. This included Max Tennyson - who unknowingly once saved the project from being scrapped - and Xylene.


Vilgax made it his life's mission to chase after the Omnitrix and use it to amass an army of aliens. He got very close, chasing down Xylene who would be transporting it to Max, but ended up critically wounded and out of commission for an extended period. Because there was no time to inform Max, he was not immediately prepared for its arrival, so Max's grandson Ben who had been both physically and genetically close enough to Max would go onto receive the prototype Omnitrix. During a summer road trip, Ben would learn to control the Omnitrix's features.

At age 12, he would put down the Omnitrix to focus on his own life. At age 15, following renewed alien activity on Earth, Ben would don the device again in Ben 10: Alien Universe's first two seasons.


It would later be destroyed and replaced by the Ultimate Omnitrix - intended as the final version - with Ben 10: Unleashed, the episode and subtitle for the third season of the series. The device also known as the Ultimatrix was incomplete when stolen by Albedo, and completed with the evolutionary function he demanded he have.

Assault Omnitrix[]

As of Limited, Ben was confirmed to be wearing the Assault Omnitrix instead of the Ultimatrix.

The Assault Omnitrix was initially destroyed in Ultimate Solution and rebuilt by the end of the episode. A second version, the Mark II (2), was built and ready for Overcoming Adversaries.

The Assault Omnitrix was again broken in Prelude of the Unleashed. It was later revealed that it could not be rebuilt (at least, any time soon) because a Primugen power source was required (which had been in the hands of the enemy at the time). It was replaced by Future Ben's Omnitrix, which was also later broken from misuse.

Azmuth was told the secret to a Primugen-free power source for the Omnitrix at the end of Ben 10: Alien Universe Unleashed. The Assault Omnitrix's newest iteration, the Mark III (3), was then built and ready for Meet the Replacements. In Plight of Pinocchio, after Eunice seeks to become a "real girl," it is revealed the Primugen-free power source is sucking an Anodite dry. Zennith and Altrazon endlessly derided Azmuth for this, before he would opt to try and find a better way.

Alphaline Omnitrix[]

First appearing in New Girl, the Alphaline Omnitrix was a new Omnitrix Azmuth was building for Ben. After being warned of a calamity Ben couldn't stop alone, Azmuth sent the Alphaline Omnitrix to Earth where it would be received by Mercedes Barnes. Her life would quickly tumble downhill, evading capture for some time by the Thep Khufan Armada, but finally being taken and brainwashed by them to become the second Mistress (after the death of the first one).

After being thought dead after Welcome to Chronospect, she would appear again under the guise of Dawn in Shades of Dawn, using the Alphaline Omnitrix. She would be robbing Bellwood right under Ben's nose so she could gain the resources to get to Azmuth, while also working on an alternative plan involving Dr. Animo and Darkstar. Both were in an effort to save her from death due to a critical flaw in the Alphaline that was sucking her dry.

Revealed in Dusk, the flaw killing her was that the power source for the Alphaline was its namesake character Alpha, a special nanite from Generator Rex's universe. He would be eradicated, and the Alphaline removed following her temporary death. She would be revived by Healding and Azmuth would rebuild the Alphaline with a more ethical (but thus far, unknown) power source that limits transformations down to 10 minutes at a time. He re-gifted the Alphaline offscreen during Escalation, trusting that she would do good with it.

Mark I-II Features[]

The Assault Omnitrix has all the basic functions of an Omnimatrix, as it has been built by Azmuth, but it is meant for big battles. In the setting it is in for the current Ben of the alternate timeline, it very much resembles the Ultimate Omnitrix (Ultimatrix). It brings back the evolutionary function (something Ben begged for, not something Azmuth decided he would just put in). There is also a mode, which the alternate timeline Ben prefers, that leaves the Omnitrix attached to the chest of the user in human form. This causes it to help keep the heart powered, and also helps by drawing power from the heart when absolutely necessary.

Like the prototype Omnitrix, the Assault Omnitrix utilizes the Hidden Universe. As opposed to its predecessors, though, it also utilizes the Codon Stream. The Codon Stream is the prime source of all DNA samples, while the Hidden Universe is a backup in case the wireless systems (or even more than that) are down.

Alternation Omnitrix is a mode in the Assault Omnitrix that allows the user to downgrade the operating system, making it faster but more likely to break. Ben uses this in close battles when he wants Master Co​ntrol but wants less power drawn. Despite the fact that the Assault Omnitrix draws less power compared to the original due to the old battery constraints, using the old Omnitrix prototype operating system allows for even less usage of the new battery.

Swap Mode is a mode where the user can switch bodies with another Omnitrix users. This is meant for when the alternate timeline Ben travels to alternate timelines and wants to unlock forms they don't currently wield. The alternate timeline Ben has used it on numerous occassions when he came across other Ben's.

The function is supposedly well-hidden in every version of the Omnitrix, but if not, can be added by simply using Swap Mode on said non-functional Omnitrix.

The evolutionary function is a feature carried on and enhanced from the Ultimatrix. Azmuth was reluctant to bring it back with the new watch, but in this timeline, he did it after seeing how the function turned the tide of battle on some occasions.

Master Control is a function in every iteration of the Omnitrix that gives complete control over all other settings to the user simply by voice control or easy-to-use dial turns. Master Control is Safeguard 30 (see Safeguards).

The Trion Lockdown Mode is a function unique to the Assault Omnitrix. Its exact purposes are unknown, but it causes the user to be restricted to the use of a certain number of aliens. The function was first used in Limited where Ben had been locked to Spidermonkey, Swampfire, and Articguana (had originally been Humungousaur, but Scarogus changed it). It later appeared in Threat or Menace where it had been locked to just Upchuck.

The compatibility layer allows the Omnitrix to still be used for DNA samples where direct mapping is not available, such as in the case of an energy being or a partially-inorganic sample. To allow usage, the Omnitrix produces the sample on top of the user's normal form, rather than simply transform them. In some other cases, the transformation is too dangerous to use on its own, so while the transformation is performed, it might be given special armor not native to the species. These scenarios apply to six (6) known transformations:

  • Upgrade (partially-inorganic)
  • Nanomech (partially-inorganic)
  • NRG (dangerous)
  • Anos (energy being)
  • Wavelength (dangerous)
  • Seismix (???)

Safeguards are features of the Omnitrix that, by definition, keep the user safe in as many ways possible. Depending on the number of active (or in some cases, inactive) safeguards, different precautions are taken in different situations to provide the best level of safety for the user.

The Safeguards that have been deactivated by Azmuth include the first safeguard, which controls the choice of different transformation in dire situations. This was shut off in Infernosphere. Also the second safeguard, which allows Ben to dial in teleportation keys (such as the one used in Infernosphere). This was disabled sometime before Infernosphere. Safeguard 11 was deactivated in Welcome to Chronospect. The same episode revealed Safeguard 30—Master Control.

Mark III Features[]

The Mark III model of the Assault Omnitrix provides a brand new experience for its user, featuring upgraded artificial intelligence which has been highlighted and used in many episodes of Season 2 of Back in Action: Alien Universe; reworked safeguards (yet to be shown); upgraded playlists (yet-to-be shown); a new power source (supplied to Azmuth by his future self just after the events of Ben 10: Alien Universe Unleashed); and more yet-to-be revealed features.

While many new features have been introduced, the Assault Omnitrix Mark III returns to the table many old favorites, including the already-displayed Recalibration Mode. While the Recalibration did not change its shape from prior models due to the fact that it had already been a good fit for Ben, it was also shown that it could be toggled manually and all aliens could be handpicked by an outside source (similarly to how the original Ben 10,000 had done so for Ken).

  • Every time Trion Lockdown Mode has been activated, it was done by Darkstar through blasting the Omnitrix.
  • Master Control being Safeguard 30 is a reference to the original Ben 10,000, who first appeared at age 30.
  • It is suggested that this is the Omnitrix he received instead of the final Omnitrix during the events of Omniverse.
