10 Insane Superman Crossovers You Won't Believe Exist

10. Thundercats/Superman

The list kicks off with a one-shot crossover comic storyline that saw the Man of Steel come face to face with the cat-like warriors from the beloved sword-and-planet franchise.

This tale saw the Thundercats tracking the villainous Mumm-Ra and Lantana Lin into the DC universe in an attempt to stop him from uniting various powerful orbs that would yield devastating results for the Thundercats' homeworld of Thundera.

The ensuing events lead the Thundercats towards Superman's direction and the heroes inevitably clash - as is the norm with these crossovers. Despite being injured by Lion-O's magical sword, Superman is able to dispatch the intruders and then reach an understanding in order to foil Mumm-Ra's plans.

The story is nothing to write home about and features out-of-character moments for Superman and his supporting cast (specifically Lois Lane and Jimmy Olsen), but at least the Thundercats fare pretty well in comparison, given the inherently cheesy nature of their lore.

However, the story leans into the cheese, and is also unburdened by the continuities of the respective universes, making the crossover a fun and easily digestible read for fans of both properties who wish to indulge in a story that does not take itself too seriously.
