There is no battle. Iroh wins.

The hell man? This argument makes no sense! Iroh is an old man who can firebend,

Aang is the most powerful being of his time!

Theres no competition!

Ok: If Chuck Norris went against God in a fight, who would win?

”Size is no guarantee of power.”

THIS IS A FIGHT BETWEEN IROH AND AANG!!
