Theorem was one of the many Decepticons imprisoned aboard the Alchemor. Along with Simacore and Axiom, he escaped when the ship crashed on Earth. Theorem and Axiom accompanied Simacore's raid on a particle research facility, and were deployed in the initial clash with Bumblebee, Strongarm, and Grimlock, although they both overshot their targets. Theorem wound up fighting Bumblebee. Simacore later used them to try and claw through a door, although neither of them could get through. Instead, the two Mini-Cons strapped Strongarm and Bumblebee to a particle accelerator cannon, then returned to Simacore. Along with Simacore, they were eventually defeated by Grimlock and returned to a stasis pod.
Season 4 Edit
Since Simacore was able to escape his corrupted stasis pod, He used Vertebreak's old lab, as a clone-making factory. Thus, he was able to create hoards of clones of Theorem and Axiom. Thankfully, Grimlock used his hyper-speed to spin at top speed to create a tornado to destroy all of the remaining mini-clones.
- Like how Jetstorm and Slipstream are voiced by the same voice actor- Roger Craig Smith, Axiom and Theorem are both voiced by the same voice actor- Jeff Bennett.
- Theorem may resemble a primate, but he doesn't howl or gibber until season 3, where his mini-clones were making all sorts of simian-like noises.
