Ben's Arsenal is the official title given to the collective alien transformations inside of the Omnitrix that Ben Tennyson can transform into.


The Omnitrix was created by a Galvan named Azmuth sometime after Earth Year 1133. His intention was to make up for his parsimonious ways, bring peace between all intergalactic species, and provide a way to resurrect any species that could conceivably go extinct.

The Omnitrix's creation was generally kept a secret, but when rumors spread through the galaxy of its existence, many forces sought out to wield its power for themselves as a weapon; most notably, Vilgax the Conqueror.

At some point during the Earth Year 2006, the Omnitrix was being transported to be brought to Max Tennyson, considered to be one of the greatest Plumbers of all time. The device's transport ship was caught in a battle with Vilgax, and the Omnitrix was jettisoned for protection, and so it fell to Earth and crash-landed before a 10-year-old Ben Tennyson.

As his DNA registered close enough to Max's, the Omnitrix vaulted onto Ben's wrist and adhered itself with his DNA, granting him access to the first Playlist in Ben's Arsenal - The Original Ten.

With great experience and practice, Ben explored the potential of his transformations as well as the Omnitrix itself and grew smarter and more powerful with it over time. He has since unlocked the Master Control and makes it his mission to understand every transformation available, as he believes they all have a purpose. Ben uses about 400 transformations regularly and has become around 2,000 so far just trying them out.

All of Ben's transformations (as of April 2021) that have a 5 Years Later design.

Becoming An Alien

The Omnitrix organizes all 1,000,912+ transformations into sets of ten, known as "playlists". Playlists are either pre-programmed into the Omnitrix, organized in a way that diversifies the grouping of species, or is expanded upon whenever Ben obtains new alien DNA by scanning an uncatalogued species.

Although transformations are instant, they can be elaborated on for aesthetic purposes.

The Omnitrix transforms Ben into the healthiest physical peak of that species' potential, but only relative to his age. At age ten, he became a ten-year-old Tetramand, at age sixteen, a sixteen-year-old Tetramand, and so on.

The specific transformations Ben becomes also carry unique traits exclusive to Ben, but consistent enough with the original alien to be a plausible member of the selected species. Ben does not become an exact copy of the alien's DNA Sample, but a version of what he would be like had he been originally born as that alien.

When becoming an alien, the Omnitrix implements the alien's basic instincts and abilities into Ben's mind when his DNA temporarily merges with the alien*. This allows Ben to get a feel for the transformation's capabilities, but after some time in that form, Ben is usually able to push his transformations beyond their limit and use their abilities in creative and combative ways.

Ben names each one of his transformations to give them an identity. Some transformations' instinctive personalities are so overwhelming that they cause shifts in Ben's behavior when he uses them; however, Ben has gotten a lot better at controlling these transformations with time.

The Omnitrix is also capable of giving aliens specific equipment if they pose a danger to other people, like NRG and his armor. The transformations themselves also take place 0.8 seconds from each other.

* The Ultimatrix did not do this, as it was a hastily-built and incomplete Omnimatrix that was eventually shelved.

Special Playlists

These Playlists are created to categorize a specific group of transformations. These transformations are also listed in the all-inclusive Arsenal list below in their appropriate slots.

The Powerhouse Playlist

Ben's personally-selected "worst case scenario" arsenal filled with the ten most powerful transformations that he knows of. These transformations are ordinarily locked on The Active Playlists but can be unlocked if the user enters the code 4317. When activated, the vents on the Omnitrix in Uniform Mode light up.

The Parasite Playlist

This playlist is for transformations that can be used to enhance the abilities of an already existing transformation, but cannot exist as transformations on their own. It uses a dual transformation-selection interface, requiring Ben to first select a parasitic transformation, and then select the main transformation to act as a host. Combinations are only possible if the two species are compatible. Heatblast, for instance, cannot be used alongside Overkill, due to fire being one of the main weaknesses of a Klyntar.

The Monster Playlist

This Playlist categorizes all of the transformations from the Anur-System. Production-wise, all of these transformations were designed to resemble icons and monsters from the horror genre. The dangerous, radioactive mineral known as Corrodium is intertwined with the ecosystem of each species listed here.

  • Ben's Arsenal was a name developed by Kuro to label the official list of Ben's Transformations. The word "arsenal" was chosen to mirror Ben's quick-changing versatility with how he uses his transformations, as if they were a fully-stocked arsenal.
  • The only species currently shown in 5 Years Later that is confirmed to not be in Ben's Arsenal are the Kryptonians, Brumarans, Eter'Caneic, and Anodites.
    • If Kryptonians were in the Omnitrix, the species would not be part of the Powerhouse Playlist, as they are still out-classed by Atomix.
    • The Eter' Caneic are extinct, but if Ben encountered a preserved specimen of enough quality he could obtain the transformation in a similar manner to that of Whampire.
