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 is operating as a mercenary and is hired by the Rose to kill Spider-Man, but is thwarted by the Black Cat. He again attempts to attack Spider-Man, but changes his mind and departs when he witnesses Spider-Man saving innocent bystanders. During the Secret Wars II storyline, Puma later confronted the Beyonder in New York; however, the Beyonder simply transported him to downtown Tokyo. Puma became enraged at the death of Master Muramoto as the inadvertent result of the Beyonder's actions. Puma reached a state of "harmonious enlightenment with the universe" and was imbued with immeasurable power. However, doubting his own senses, Puma lost the mystical power just as he attacked the Beyonder. Puma was able to learn Spider-Man's secret identity, Peter Parker, thanks to his enhanced senses, and now felt he owed him a debt of honor as a result of the Beyonder affair. He offered Peter Parker a job at his company while Peter was on his honeymoon in France; however, Peter declined the offer. Puma later attempted to clear Spider-Man's name of a crime he didn't commit, and first encountered Silver Sable and The Outlaws. When the mutant powers of Charles Little Sky, a kinsman of Fireheart's (and the man later known as Portal), first manifested, Fireheart tried to help his fellow tribesman better understand his powers. Rejecting Fireheart's offers of aid, Portal fled to Ellis Island where Fireheart caught up to him. When Portal's powers activated again and returned the U-Foes to Earth, Fireheart was forced to team up with the Avengers as Puma to protect Little Sky, helping to defeat the villains. Puma then battled Spider-Man in New York. Fireheart actually purchased 51% of the Daily Bugle, made Robbie Robertson publisher, and began a pro-Spider-Man campaign in the publication, in an attempt to pay off his debt of honor. During this time, he was nearly killed in an attack by the Hobgoblin, but was saved by Spider-Man. Fireheart agreed to join Spider-Man's rag-tag superhero group called the Outlaws, along with several other Spider-Man adversaries-turn-allies (including Sandman, Rocket Racer, and the Prowler). The group clashed with the Avengers, until it was revealed that both groups were actually being manipulated
