Kipotli

Kipotli is a warrior of the Nahuatla Tribe and an insane criminal.

The Avatar found him sitting in a prison cell in Tichticotl in Savage Empire. Talking to him revealed a disturbing madness. A madness, in which he'd murdered his own officers, and murdered all who opposed him. Eventually the Nahuatla warrior had overwhelmed him and captured him, preventing further slaughter. Kipotli told the hero he would join their party if freed from the Nahuatla prison, but would immediately cross the Avatar upon gaining his freedom and attack.
