Thomas Fireheart

Thomas Fireheart is a Native American businessman of the Kisani Nation who serves as CEO of Fireheart Enterprises. Through years of rigorous martial-arts training in Japan and a mystical tribal legacy, he can transform into the superhumanly powerful Puma, a fearsome human-feline hybrid.

Thomas Fireheart made his mark on Marvel's Bronze Age when he debuted in Marvel Age Annual #1 in 1985, the product of a creative team that included Jim Shooter and Kurt Busiek — serious pedigree for any character's origin. Over four decades of publishing history, he's woven himself into the fabric of the Spider-Man corner of the Marvel Universe, appearing most prominently in The Amazing Spider-Man and Web of Spider-Man, where he keeps some very distinguished company — including Spider-Man himself, Peter Parker, and the Human Torch. With two key-issue appearances to his name and a presence that stretches all the way to Venom War: Lethal Protectors in 2025, Thomas Fireheart is the kind of character who quietly accumulates significance across Marvel history, well worth tracking down for any serious Spider-Man collector.
