Niels
Niels is a cat who was exposed to the same kinetic energy experiment that gave Robbie Baldwin his Speedball powers, leaving the feline with a similar ability to bounce uncontrollably — making him Marvel's most accidentally super-powered house cat.
A Marvel cat with a flair for the extraordinary, Niels bounded onto the scene in 1988's Speedball #1 — a Copper Age debut courtesy of the legendary Steve Ditko and Tom DeFalco. Over a remarkable three-decade stretch, this feline has shared pages with the likes of Robbie Baldwin, Steve Rogers, and the cast of Damage Control, popping up across titles as eclectic as Guardians Team-Up. Fourteen catalog appearances may sound modest, but for a cat who's rubbed shoulders with some of Marvel's most colorful corners, Niels is a delightful deep-cut worth seeking out.
