Decimus Prime is the Omnitrix's DNA sample of a Cybertronian from the planet Cybertron. He is exclusive to Ben Prime's dimension.[note 1]


Decimus is a large green robotic humanoid. He has white fingers, two rods sticking out of his back as well as tires on his shoulders and legs. A large Omnitrix logo on his chest, with the real one in the middle.

Powers and Abilities

Decimus is able to transform into a car that allows him to drive at high speeds.

Decimus probably has some type of energy melee weapon.[DJW 2]

Decimus is not vulnerable to Archa 7 arachnids because they are not considered a natural predator to Cybetronians.[DJW 3]



Upgrade's mecha form in OTTO Motives


  1. The transformation, being created by Art Director Derrick J. Wyatt long after the series ended, is non-canon and unofficial. Derrick considers Decimus in particular a "What If" situation unless a crossover could ever actually happen, which are no more than "imaginary stories" until they do.[DJW 1] The legitimacy of this transformation is up to the reader.
