Mike Crobe appears in the Madballs comic book in issue 10. He was a virus in Dr. Frankenbeans's body that was released after the doctor fell ill as a result of his built-up frustration from continuously failing to defeat the Madballs. In order to save the doctor's life, the Madballs are shrunk by Snivelitch using Rojad's shrink ray so they can enter the villain's body, find the virus, and eliminate it. After searching, they are informed of Mike Crobe by Perry Mecium. The Madballs then defeat Mike Crobe and get out of Dr. Frankenbeans' body before the effects of Rojad's shrink ray wear off.
