Rebootomnitrixsymbol This article belongs to the Reboot Continuity

Gax was the Omnitrix's DNA sample of a Chimera Sui Generis from Vilgaxia.


Gax resembles Vilgax, however he has black armor that has a white stripe on the chest. He has spikes on his knees and shoulder pads and has six green tentacles dangling in the front of his face. His tentacles and arms fade into brown, and he wears black, fingerless gloves. He has green sacs on the side of his head and red eyes.

Gax wears the Omnitrix symbol on his chest.

Powers and Abilities

  • Tentacles/Wall Climbing/Shapeshifting Arms
  • Laser Vision/Sharp Shoulder Spikes
  • Enhanced Strength
  • Enhanced Durability
  • Enhanced Jumping/Agility

Gax is strong enough to lift the Rustbucket, a giant boulder, two giant trees, and a CascanOmni-Tricked: Part 4 with relative ease.

Gax can also project powerful laser beams from his eyes. His optical lasers are capable of starting fires if Gax chooses to do so.

Gax has shapeshifting arms that can change into a bunch of tentacles (five on each arm). These tentacles are very powerful and retain equal strength to his arms as a whole.

Gax is demonstrated to be a very skilled climber, using his sharp claws to dig into the ground.

Naming and Translations

Language Name Origin
Romanian Gax From the original English name.
Russian Гакс From the original English name


Gax's name is half of Vilgax's full name; this is a reference to the connection between the alien and his genetic donor.


  • Gax shares some similarities with the classic continuity alien, Feedback:
    • Both are additional aliens voiced by Yuri Lowenthal.
    • Both quickly become Ben's favorite alien to the point that he is majorly excited to use their transformation over any other regardless of the situation.
    • Both were removed from the Omnitrix by major villains, Gax being taken out by Vilgax and Feedback being taken out by Malware.
    • Both each have their own theme song.
  • Gax is also similar to Ghostfreak, as both were part of Ben's alien roster until they were removed and became villains; though Ghostfreak was really Zs'Skayr trapped within the Omnitrix while Gax was absorbed by "Vil".
  • Despite his DNA pod being repaired off-screen, Gax no longer exists within the Omnitrix.[DR 2] However, it is strongly implied within the cartoon that Gax was locked rather than destroyed.[note 1] In fact, it is possible that Gax might return in a future season.[DR 3]
  • When switching his arms into tentacles, each individual finger becomes a separate tentacle. Although often missing due to animation errors, Gax's gloves do not disappear when his arms become tentacles. They are worn by a fifth tentacle that does not form one of his fingers when part of a normal arm.


  1. This is observed during Animo's transformation into Rath, as Gax's tentacles are briefly seen.Animorphosis

    • Different continuity, Ben has no reason to think of that one. Overkill is hard to associate with anything, actually.
    • I know there wouldn't be an in-canon reason, I just thought it would be a fun easter egg for fans of the original series
  • Could Reboot Aliens be in the Main Timeline Omnitrix? Vice-versa?
