== Powers and Abilities ==
Superhuman Strength: Thunderbird is superhumanly strong and can lift approximately two tons under optimal conditions.
Superhuman Stamina: Thunderbird's muscles produce less fatigue toxins than the muscles of ordinary humans. He can exert himself at peak capacity for several hours before fatigue begins to impair him.
Superhuman Durability: Thunderbird's muscle tissues are three times as dense as those of a normal human being and are distributed in such a way so as to give him massive shoulders, arms, and thighs. His skin is also several times as dense as that of a normal human being's and includes an additional layer of leathery epidermis.
Enhanced Lung Capacity: Thunderbird's lungs are oversized, and his respiratory system is developed in such a way so as to allow him maximum wind and endurance with a minimum oxygen intake. These features make him a natural outdoor fighter and athlete.
