Harry Wilson is one of the main protagonists in the For Real Segments. He is played by Matthew A. Wilson and frequently gets himself into comical dilemmas that he solves using math.

He has various love interests and an obnoxious cousin named Harley, but it is unknown which of either man's parents is related to which one.

It is revealed in the "For Real" segment "Harry Gets Nosey" that Harry is allergic to cats.

The last name stays the same as the actor, but it is possible that the character's name is Harry to avoid confusion with the animated Matt.
