When a fantasy show has an ensemble of characters, one of the filler episodes can be to have those characters encounter an embodiment of fear, which manifests as what each character’s afraid of the most. It’s an old formula, but it’s used so commonly because its effectiveness is determined by how well-written your characters already are. There are many animated shows that have employed the device, and it’s finally time for Hulk and the Agents of S.M.A.S.H. to do the same.
When I first experienced Ultimate Spider-Man with Venom Bomb, my most positive thoughts on it were the way it used Spider-Man as a protagonist to show the audience various aspects of the Marvel universe. If the Cinematic Universe has shown anything, it’s that, of those aspects, the best is the Guardians of the Galaxy. So it seemed logical to put them together at some point.
