Thunderbird

James Proudstar, younger brother of the original Thunderbird, is an Apache mutant with superhuman strength and speed who debuted seeking revenge against the X-Men, whom he blamed for his brother John's death, before eventually finding a different path among Marvel's mutant community.

Thunderbird made their Marvel debut in the pages of The Uncanny X-Men #193 in 1985, brought to life by the legendary Bronze Age creative team of Chris Claremont, John Romita Jr., and Dan Green — a pedigree that signals this character arrived with serious intent. Over four decades of publication history, Thunderbird has woven through some of Marvel's most beloved corners, appearing most prominently in The New Mutants, Firestar, and Uncanny X-Men, sharing adventures with heavy-hitters like Wolverine and Magik along the way. Two of those appearances carry key-issue status, making this a character worth tracking down for any serious collector. With 40 years of continuity and a roster of co-stars that reads like a who's who of the X-Men's world, Thunderbird is a Bronze Age gem hiding in plain sight.
