Sunfire

Sunfire was one of the mutants handicapped by a device that stops mutants from using their powers. While they are handicapped, Sentinels and other rulers have been enslaving them. When they were freed, they had their turn to fight back against them. In a later episode, he also became a follower to Magneto.

Origin
Shiro Yoshida grew up with a huge resentment against the United States. His mother was exposed to the radiation of the atomic bomb at Hiroshima and she died during his birth. His dad, a member of the Japanese Clan Yashida, became a diplomat to the United Nations and Shiro was pretty much raised by his uncle.

Shiro's uncle Tomo took him to a site in Hiroshima, and got him to touch the ground. There, the radioactive soil somehow triggered his mutation. Shiro trained for months before he was able to control his flame fully. His uncle Tomo was purely anti-America. He instilled his hatred upon Shiro and is responsible for giving him his costume and codename of Sunfire.

Powers and Abilities
Sunfire can biochemically ionize matter and convert it into the super-heated plasma state of matter, generating temperatures of about 1,000,000º Fahrenheit which he most often releases as force blasts from his hands. Sunfire can recharge and enhance his stored power by absorbing both solar and electromagnetic energy. He can also view his surroundings in the infrared spectrum. Sunfire can create super-heated air currents which enable him to fly while leaving a trail of flame behind him. Sunfire also generates an invisible field of psionic energy which protects him from the heat and radiation generated by his own powers, as well as from outside sources. The field also shields him from air friction and the light generated by his plasma, as well as lending a certain level of protection from kinetic impact.

Sunfire is well versed in the martial arts of karate and kendo, as well as the art of bushido, the history and customs of the samurai class.
