Jason Beck is a criminal and mechanical mastermind in "The Big O".
After being defeated by Roger Smith during the kidnapping case, Beck's further appearances on the show consist of his trying to defeat Roger. However, his plans continually degrade from sinister and dangerous to almost comical in nature.
Beck becomes Alex Rosewater's agent in "Twisted Memories" after Alan Gabriel threatens him with an order of execution, but is unhappy with this situation despite a successful attack on Roger. Thus, he betrays Rosewater and ends up aiding Roger in the last episode by telling Dorothy how to activate Big O's Final Stage.
