WilyKat

WilyKat is a young Thunderian cat-person and one of the ThunderCats, a group of humanoid felines who flee their dying homeworld of Thundera. The mischievous twin brother of WilyKit, he relies on agility and cunning rather than brute strength.

Few characters capture the scrappy, adventurous spirit of the Bronze Age quite like WilyKat, who burst onto the scene in Thundercats #1 in 1985, brought to life by the creative team of David Michelinie, Leonard Starr, and Jim Mooney. A Marvel Comics mainstay from the franchise's very first issue, WilyKat has shared pages across four decades with some of the most iconic names in the ThunderCats roster — Lion-O, Cheetara, Panthro, Tygra, and WilyKit among them — making for genuinely thrilling company. That the character has remained a presence in the catalog all the way through 2025 speaks to the enduring pull of the ThunderCats universe and the loyalty of its devoted fanbase. For collectors tracing the full arc of this beloved franchise from its Bronze Age origins to the present day, WilyKat is a cornerstone figure well worth seeking out.
