The Antitrix is a knock-off alternative to the Omnitrix created by Kevin Levin on Earth.


The AntiTrix is a makeshift replica of the Omnitrix's season 1 model, with the dial symbol turned red and appearing in half, resembling a letter 'K', and with the addition of four metal protrusions ending in red lights.



  • The Antitrix is a DNA-altering device, using the cross-contaminated mutated alien DNA it contains to transform the user into a monstrous mutant fusion of any two species.[DR 1]
  • The Antitrix has a quick change feature, allowing Kevin to change forms.[1] This can be accomplished in one of two ways:
    • The first is by pressing the symbol on the aliens' chests.[2][3]
    • The second is by simply willing it.[4][5]

Symbol Position

  • The Antitrix symbol is generally located on the chest of the transformations.


  • The Antitrix is able to clothe and provide genetic armor for most of the transformations.

Between the events of Seasons 2 and 3, the Antitrix was created by Kevin when he gained the blueprints to the device in a dream. However, the boy arrogantly decided to make minor modifications to the device, making the aliens Kevin becomes somewhat different and more powerful, than their normal variants, but also unstable.[6]

  • Unlike the Omnitrix it is modeled after, the Antitrix can have 11 transformations unlocked at a time, instead of 10.[7][8]
  • The Antitrix can keep Kevin transformed for much longer than the Omnitrix. This proven in certain episodes, as the screen-time for an Antitrix alien is equivalent to the screen-time of two Omnitrix aliens.
  • The Antitrix has been referred to as such only in marketing. In the series, Ben and Kevin both refer to it as an Omnitrix.[6][9]
  • The Antitrix is ​​similar to the Ultimatrix in several ways:
    • Both were created by a villain, who took the basic Omnitrix blueprint/core and added extra features onto it by themselves.
    • Both of them make the aliens more powerful in combat.
    • The creators of both are, in some ways, a counterpart of Ben.
  • The Antitrix is also similar to the Biomnitrix in the sense that the transformations are fusions of any two species.
  • All of Kevin's Aliens share the same voices, a influence of how voice actor Dee Bradley Baker voiced all of Ben's aliens from the Ben 10 Alien Force/Ultimate Alien franchise (Except Rath).
