Puma (Thomas Fireheart) is a fictional character in the Marvel Comics universe most closely associated with Spider-Man. While originally a villain, he gained a great respect for Spider-Man and became his occasional ally. He first appeared in Amazing Spider-Man #256 and was created by Tom DeFalco and Ron Frenz.

Puma's real name is Thomas Fireheart, and he is of Native American descent. The tribe he belongs to (located near Hartsdale, New Mexico; Marvel Westerns: Western Legends suggests that the tribe may be the Kisani, as one of Puma's ancestors belonged to that tribe and lived at Lost Mesa) has had an ancient prophecy of the coming of a powerful being who might destroy the world for generations. Long ago, they began making preparations for this coming doom. They used mystic ceremonies and selective breeding to create a perfect warrior. Thomas Fireheart is the latest in this line of men. Though he never believed in the prophecy, he took his duties as protector of his tribe seriously, and has strived his whole life to be the best he could be, mastering his ability to turn into a powerful humanoid mountain lion werecat. He also trained in Martial Arts in Japan under a man named Master Muramoto.

Very intelligent, and with a good business sense, he became owner and CEO of Fireheart Enterprises. Headquartered near his tribe in Hartsdale, Arizona, it is a multinational corporation involved in many different endeavors, with regional offices around the world. Becoming bored with corporate life, he began to seek greater challenges, and offered his skills as Puma for sale.

He was operating as a mercenary and had been hired by the Rose to kill Spider-Man, but was thwarted by the Black Cat. He again attempted to attack Spider-Man, but changed his mind and departed when he witnessed Spider-Man saving innocent bystanders.

Puma has not been a contender in any CBUB matches.
