THUNDERBIRD I

 

THUNDERBIRD I

Real Name: John Proudstar

First Appearance: Giant Size X-Men (Vol. 1) #1, May 1975

Powers: Thunderbird I’s mutant powers were superhuman strength, speed, and endurance. He was strong enough to lift up to two tons. His muscle tissue was extremely dense and distributed in such a way as to give him massive shoulders, thighs, and arms. His skin was extremely dense as well, with an additional leathery epidermis, granting him superhuman durability. He possessed oversized lungs and a respiratory system that allowed him maximum wind and endurance with a minimum of oxygen intake. He could run at speeds up to 35 mph. Thunderbird I died before his powers could be fully refined or developed.

John Proudstar had military training from serving as a US Marine, having earned the rank of corporal along with several medals.
