A fun reminder that Aang was a terrifyingly powerful Avatar.
Most Avatars are informed of their newfound destinies at the age of 16 to begin their training. Because of the approaching war Aang was told of his status at the age of 12. He had already mastered airbending, and in the span of a year he mastered the other three elements, the avatar state, and energybending. He also learned lightning redirection and seismic sense (a technique no previous Avatar had even encountered). <>In the span of a year>.
This child was a terrifying force of nature.
