Ruebix Torque is a Dimensio-Agent. In Heroes, he was first seen as a villain in season 1. He was later revealed to be a Dimensio-Agent and a good guy.
In Heroes's first season, Torque is seen joining Makuta in his attempts to defeat the heroes. He spent a lot of time socializing with his understudy, Bugboy/Ruebix Bug. Ruebix Bug reveals in The Hero Report that during the season finale, Torque revealed that he was simply acting as a villain for the purposes of the Hero Experiment. He then takes Ruebix Bug under his wing to train him on how to be a Ruebix.
It is unknown what Torque did during the second season, but it is implied that he spent this time on other missions or training his apprentice.
Ruebix Torque is the only Dimensio-Agent seen so far without a name where the consonants are capital letters and the vowels are lowercase. This is due to the fact that he is a Ruebix, the police of the Dimensio-Agents.
