The Decatrix was created by a mysterious scientist on Galvan Prime. Unlike the Omnimatrices of other universes, the Decatrix primary function was for combat. Hence, each of the DNA samples within the Decatrix have been slightly altered to be geared towards combat. Diego later upgraded the Decatrix to become the; Duomnitrix.

When activated, Decatrix is able to fire a bolt of energy on the users command. The power of these bolts can be modified by the user by pressing the holographic buttons on either side of the gauntlet. The core glows yellow.


When DNA not in the database is near the Decatrix, it automatically emits a green beam that passively scans the target's DNA and adds it to the database. This function can also be used to identify injuries and weak points of an opponent to use as an advantage in combat. The core glows green.

Evolutionary Function

  • The evolution works by running an alien's DNA through a combat simulation for a million years and altered to fit the current transformation
