Michael Peterson was the best friend of Steve Harmon. He was kidnapped by the clowns from Dimension X, and was saved by Steve, who had been mutated by Unstable Molecules. Michael recognized his friend and helped him pick the superhero name, Slapstick.
Mike and Steve went to the American Museum of Natural History for a school project. However, their visit was interrupted by Dr. Yesterday, who wanted to use the museum to focus his powers. When the New Warriors showed up he brought to life a skeleton of a Tyrannosaurus Rex and summoned several warriors from the past to help him. While the heroes took on the threats, Mike tried to find a way to help, but was captured. Mike was freed when Dr. Yesterday set things right again.
