Mike Sorayama went to college with Pete White, Rusty Venture, Baron Ünderbheit, Brock Samson and The Monarch. He was friends with Pete, Rusty and Underbheit, and a tutor of Leslie Cohen, whom he developed feelings for.
Sorayama grew resentful of his roommates after they: played a joke on him by filling a bong with oregano, which he is allergic to, causing him to seek medical assistance instead of spending time with Leslie; teased him about his crush on Leslie, with Pete White, the college station's disc jockey, humiliating him by reading a fake dedication declaring Mike's love for Leslie; and pretending to have sex with a "Leslie Golem" that looks just like Leslie Cohen in a game of Dungeons & Dragons. Furthermore, Sorayama was convinced that Rusty slept with Leslie Cohen, but it later turned out it was actually Brock Samson.
Sorayama eventually majored in robotics and retained his obsessive feelings for Leslie Cohen. Later in life he developed his "Lesliebots" and a robotic version of himself. When he died the robot version of himself kidnapped White, Ünderbheit, Dr. Venture, and Samson to punish them for various incidents that ruined his chances with Leslie. His robot duplicate was ultimately destroyed by Samson.
It is possible that Phantom Limb recruited Mike Sorayama into the Guild of Calamitous Intent, much as he did with Sheila and attempted to do with Billy Whalen. If so, this would explain Mike's development into a spiteful villain.
- Before his death Professor Sorayama taught at State University, the same college he attended.
- Mike Sorayama is partially based on artist Hajime Sorayama, who drew characters such as female-looking robots on which the Lesliebots are based.
- Mike Sorayama is partially based on the lovelorn character of Mike Yanagita from the 1996 film Fargo, who is romantically obsessed with the film's lead character, Marge Gunderson. Comedian Steve Park portrays both characters.
