Wu Teh and his brother Ling were augmented by the radiation they were exposed to from the explosion of the dormant bomb on top of Mt. Fuji. Though it is never shown exactly how this radiation changed them, it is implied that like their grandfather, they became full of vigor and strength. Beyond these abilities, Wu Teh was a skilled martial artist who mastered several forms of hand-to-hand combat while at the monastery in the Himalayas.
