James Proudstar admired his solider brother John Proudstar who fought for mutant rights as the X-Man - Thunderbird. When Thunderbird perished on his second mission with the X-Men, James Proudstar blamed Professor X for his brother's death.
After drifting between his reservation and a few mutant teams, Proudstar returned home to find his tribe slaughtered by what he believed to have been the Hellions. Proudstar joined the New Mutants in a quest for revenge against the Hellions as Warpath.
