===Allies===
* '''Sgt. Mike Cosgrove''' (voiced by [[Ed Asner]])&nbsp;– A gruff yet kind-hearted police sergeant who is friends with Freakazoid and several other characters. He has the ability to get people to stop what they are doing by pointing at something and saying "Cut it out". He can also find Freakazoid no matter where he is, and often interrupts him to ask him to visit various entertainments, which Freakazoid always agrees to. During this visit, Cosgrove reveals important information about the plot of the episode, resulting in Freakazoid leaving to foil the villain's scheme. Additionally, Freakazoid entrusted Cosgrove with his secret identity, and is upset when he accidentally reveals it to Steff and Professor Jones.
* '''Roddy MacStew''' (voiced by [[Craig Ferguson]])&nbsp;– Freakazoid's mentor and expositionist. He is an ill-tempered Scotsman who once worked for Guitierrez and was the first to discover the Pinnacle Chip's flaw. Using the Chip, MacStew can travel to and from [[cyberspace]].
