Puma (Thomas Fireheart) is a fictional character appearing in American comic books published by Marvel Comics. The character is depicted as being most closely associated with Spider-Man. While originally a villain, he gained a great respect for Spider-Man and became his occasional ally.
Thomas Fireheart is a wealthy Native American businessman, but Thomas has a hidden side to him and the rest of the world. His New Mexico, Indian tribe began a secret program that combined mysticism with controlled breeding in an effort to bring about one perfect warrior to act as their protector. This warrior was called Puma. Puma was a mercenary-for-hire, and the Rose had employed him to assassinate Spider-Man. Puma may have actually succeeded if not for the intervention of the Black Cat. Since then, Puma and Spider-Man have fought many times, and Puma has even fought the Beyonder.
Puma had attacked Spider-Man, believing false charges that Spider-Man was a thief. In order to pay off his debt of honor, Fireheart purchased the Daily Bugle just to improve Spider-Man's public perception. Eventually, the Bugle was sold back to J. Jonah Jameson.
Recently during the superhero "Civil War", Puma registered with the government alongside Black Cat, whom with he is in a relationship.
