Shiro Yoshida

When most of the original X-Men were trapped by Krakoa, Sunfire was one of the mutants recruited by Professor Charles Xavier to rescue his original students. Though he had no interest in joining other mutants, Sunfire agreed by feeling honor-bound and wishing to reintroduce himself as a warrior to the world. During the mission, Sunfire formed an assault team with Nightcrawler. The rescue was a success, but right after the mission, Sunfire left the team, alleging his loyalty lay with his country only and departing on bad terms with the X-Men.
