In Avatar, children are all-powerful:
A group of kids ending the Great War.
A group of kids break into the great Royal Palace, defeating the Royal Earthbender Guards in the process.
14-year-old princess who takes control of secret police agents in a short amount of time, gaining their trust/fearing them to the point that they betray their boss and their nation.
Kids who become masters of their elements while still in their teens.
Teenagers who lead an invasion that could end the Hundred Year War.
Middle-aged Fire Navy admiral defeated by a 16-year-old, and then de facto defeated by a biological 12-year-old.
Did I forget something?
