It’s probably a bad sign when Hercules comes asking for a favor. It’s juuuuuust a little job that needs doing, but this is Hercules; isn’t he supposed to be REALLY good at doing labors himself? Before they know it, Iron Man, Spider-Man and the are stuck looking after Orthus and Cerberus, the two legendary hounds of the underworld! Luckily, the dogs learn to behave after chewing up only a few cars, a statue, and Iron Man, and finally they’re obedient enough for the Metro Dog Show! Only problem, Hercules wants the dogs back. Oh no, Herc, not before the Hulk gets his ribbon! It’s two dogs with five heads between them, and all the action you can handle.
Three superheroes on their day off? A certain god says otherwise! Hercules needs their superpowers to watch his dogs while he's away. Seems like a simple task.. until Cerberus and Orthus, legendary guardians of the underworld, burst through a wall. While Spider-Man and Iron-Man desperately want to refuse, Hulk loves dogs, and Hercules won't take no for an answer. Two over-sized canines make for one big, messy adventure through New York (and its drool-ridden rubble), with a surprisingly minuscule end.
