Test of Heroes, Part One

A new arc starts. Magic Man, it turns out, has been the one yanking Robot Finn's strings, all to impress one Betty Grof, now living on Mars. The family reunion sours fast when Magic Man's jealousy gets the better of him, and he may have just accidentally kicked off the apocalypse. Finn, Jake, Marceline, and Princess Bubblegum will need each other if Ooo is going to survive this exam. John P. Golden draws.
