But Iroh is a beast who can kill who he pleases because he is so overpowered.

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

No, Aang has all the elements and the Avatar State. To quote Fred Weasley,

”Size is no guarantee of power.”

THIS IS A FIGHT BETWEEN IROH AND AANG!!

Exactly, and Aang kicks ass.

Buff Iroh kicks everyone’s ass! No further comment.

Why @Mr. Wang Fire ?

You have no reasoning behind it-

I have many reasons. Actually:

•He is buff

•He is old and wise

•He has experience in battle

•He can redirect lightning

•He has drank the ever life tea.

…What?
