Cybernetic Technical Robot Operative, or C.Y.T.R.O. for short, is a supporting protagonist in the Max Steel franchise. Depending on the continuity, C.Y.T.R.O. is either a robot created by Dr. Gregor Rendel to destroy Max Steel, or he's built by Berto Martinez of N-Tek to help protect the base (and ultimately to protect Berto's sister Rayne should anything happen to him). One of Max Steel's most trusted allies, he would eventually transition from a mindless drone to a key member of Max's Team Turbo, along with Rayne Martinez and Alex Villar. Armed to the teeth with weapons, C.Y.T.R.O. is a physically massive and powerful, yet logic and observation-driven robot.
Jim Conrad voices C.Y.T.R.O. in the direct-to-video movies. In Bio-Crisis, Jim's C.Y.T.R.O. starts off as a threat to be eliminated by Max (before it can eliminate him), but given that his objective was to destroy Max Steel, C.Y.T.R.O. inadvertently becomes his ally by defending him against other threats that might remove Max Steel before completing that mission himself.
In the 2013 rebooted series continuity, C.Y.T.R.O. started off as nothing more than a mute and mindless mechanical minion, often used as brief comic relief as he was toted around as this grand creation, only to be easily dispatch by the villain du jour. After N-Tek's destruction, he is discovered in a storage vault by Max and Rayne, and given AI by a chip that Max found in the wreckage. Once given sentience by this advanced chip of Berto's, C.Y.T.R.O. was then given life (vocal life, that is) by Colin Murdock.
Both actors do a great job of portraying the "does not compute" robotic aspect of C.Y.T.R.O., but also the more human and comedic elements.
