Finn the Superhuman

One day while adventuring, Finn was hit by a meteor that granted him superpowers. He decided to become a superhero, with Jake transforming into a cape to assist him. Initially, Jake felt inadequate, but encouragement strengthened their bond. Note: This is an in-universe comic written by Finn and Jake, so feats do not scale to their main series versions.
