Circuit isn't an easy Autobot to trust; in fact it's best not to trust him at all. While his own interests are his only true concerns, his smooth-talking demeanor can make it seem as though he's made terrible sacrifices for the good of others. His lies and schemes have a wide reach - ensnaring both Autobot and Decepticon alike - and force Circuit to constantly travel from one location to the next or else be caught by the victims of his scams. His invisibility shield and decelerator cannon aid him in these endeavors, allowing him to slip out of sight or slow his pursuers to a crawl.

Unfortunately for Circuit, he could only run for so long. After the fall of the Decepticon Homeland, he found himself rigged with the same teleportation tag that the Autobots had latched onto the Decepticons. Instead of teleporting him back to a dead Cybertron, however, the device on Circuit malfunctioned and flung him deep in the multiverse and through the dimensional gate in Axiom Nexus.
