In January 2004, DCComics published a one-shot crossover comic between the {{ThunderCats}} and {{Superman}}.

Superman, the defender of Earth, meets the toughest 'Cats in a special CrisisCrossover event! While trying to stop Mumm-Ra's minions, the [[QuirkyMinibossSquad Mutants]], from retrieving a magical stone equal in power to the [[MineralMacGuffin Eye of Thundera]], the [=ThunderCats=] are hurled into an alternate dimension, downtown Metropolis!

While searching for the Mutants, the 'Cats accidentally cause confusion and chaos all over town. It isn't long before the Man of Steel himself steps in to put a stop to thier antics. Can the Man of Steel withstand a blow from the most powerful sword in just about ''any'' universe? Will the [=ThunderCats=] be able to get back home alive?

What do you think...?
