History
Thunderbird shared a similar history to his Earth-616 counterpart the old and new X-Men died on Krakoa. Afterwards the Ani-Men took over Valhalla Base to allow Count Nefaria to control America's nuclear arsenal and hold the world ransom. Beast formed a new team of X-Men by telepathically contacting each mutant. James was burying the body of his brother and only agreed to join if he could meet Charles Xavier whom he blamed for his brother's death and planned to kill.
The X-Men tried to attack the Ani-Men but were stopped by Dragonfly's hypnosis until Rahne Sinclair joined the battle and freed them and the Ani-Men were subdued. The Count tried to escape on a jet but the plane exploded when Banshee used her power to destroy it. She was knocked out but saved from falling to her death by Thunderbird. Afterwards he forgave Charles for his brothers death and joined the X-Men.[1]
