Aku

Aku was a Celerity Demon and mentor to Sarpedon whom he taught of the Avatar threat who in turn started stealing guardians to stand at least a small chance against them. He also led two other demons in an attack that killed Kyle Brody's parents in an attempt to get the Avatar Vanquishing Potion, but failed in getting the potion.

Aku was vanquished by Sarpedon in battle in order for the latter to prove his strength and that he was ready to deal with the Upcoming Threat.
