Powers and Abilities

Thunderbird was a mutant.

Superhuman Strength: Thunderbird was superhumanly strong and could lift approximately 2 tons under optimum conditions.

Superhuman Stamina: Thunderbird's muscles produced less fatigue toxins than the muscles of ordinary humans. He could exert himself at peak capacity for several hours before fatigue began to impair him.

Superhumanly Dense Tissue: Thunderbird's 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.

Superhuman Durability: Due to the increased density of his skin and muscle tissues, Thunderbird's body was somewhat more resistant to physical injury than an ordinary human. Although far from invulnerable, he was capable of withstanding impact forces and blunt trauma that would have severely crippled or killed an ordinary human with only mild to moderate discomfort.

Superhuman Respiration: Thunderbird's 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.


John was an experienced hand-to-hand combatant.

  • John Proudstar's younger brother James would go onto to be a member of the Hellfire Club's Hellions, and a member of the first incarnation of X-Force.
  • Thunderbird would 'return' in the episode of 'Spider-Man and his Amazing Friends' called 'The X-Men Adventure'. Except for super strength and stamina, Thunderbird also possessed the ability to call upon the power of certain animals and manifest them, something that even surprised Iceman as he muttered "I didn't know you could do that!"
  • Len Wein wanted a character to be killed off quickly during the beginning, so that readers would see how serious the new series were. Thunderbird was chosen because they thought he was too similar to Wolverine.
