History: John Proudstar was born on the Apache
reservation in Camp Verde, Arizona. During his childhood
and adolescence, he proved to be an exceptionally strong
and vigorous athlete.
Proudstar, however, regarded himself throughout his life
as a loner and an outcast. He wished to prove himself
to be a warrior in the tradition of his ancestors, and
he was dissatisfied with what he regarded as the complacent
lives led by his fellow Apaches on their reservation.
Although too young to join the armed forces, Proudstar
lied about his age and entered the United Stated Marines,
intending to lead the kind of active life he desired.
He became a corporal and earned a number of medals. But
still, Proudstar was dissatisfied with his life once his
tour of duty was over and he had returned to the reservation.
Proudstar's mutant superhuman strength first manifested
itself when, at the age of twenty, he wrestled and threw
a charging bison barehanded to save an endangered little
girl. This feat earned Proudstar fame among his tribes
people on the reservation, but the true nature of his
abilities remained unknown until Professor
Charles Xavier, founder of the X-Men, a team of superhuman
mutant adventurers, discovered him.
the use of his mutant-detecting computer Cerebro,
Xavier located Proudstar, whom he invited to become one
of the X-Men. The first mission that Proudstar and six
other new recruits to the team undertook was the rescue
of the original X-Men from the "living island" of Krakoa
in the South Pacific. Except for Sunfire, these new recruits,
including Proudstar, became the "new" X-Men team. Xavier
gave Proudstar the code name "Thunderbird."
On their next known mission, the new X-Men went to Cheyenne
Mountain in the Colorado Rockies, the location of a North
American Air Defense command center, which had been taken
over by Count Luchino
Nefaria in an international extortion scheme. After
the X-Men had foiled his plans, Nefaria attempted to escape
in a small aircraft. Thunderbird managed to climb onto
the plane as it took off. Defying Xavier's telepathic
warnings to get off the plane, Thunderbird asserted that
he was finally going to prove he was a true Apache warrior.
Using his superhuman strength, Thunderbird ripped open
part of the plane and wreaked havoc on its internal systems.
Furiously, Thunderbird pummeled the aircraft until finally
it exploded, killing him instantly. Nefaria, however,
had reached safety through teleportation.
Height: 6 ft. 1 in.
Weight: 225 lbs.
Strength Level: Thunderbird possessed superhuman
strength, enabling him to lift (press) up to two tons.
Known Superhuman Powers: Thunderbird was a mutant
who possessed superhuman strength and endurance. His muscle
tissue was three times as dense as that of a normal human
being's and was distributed in such a way as to give Thunderbird
massive shoulders, arms, and thighs. His skin was several
times as dense as that of a normal human being's and included
an additional layer of leathery epidermis. His lungs were
oversized, and his respiratory system was developed in such
a way as to allow him maximum wind and endurance with a
minimum of oxygen intake. These features made Thunderbird
a natural outdoor fighter and athlete. He could run at speeds
of up to 35 miles per hour for extended periods. Thunderbird
died before any of his natural abilities could be redefined
through the training that Charles Xavier had planned for
