Oaxtepac is the shaman of the Nahuatla Tribe in Savage Empire. Prior to the events of Savage Empire, the usurper Huitlapacti had Oaxtepac thrown into prison, since he could be a danger to his position and Dr. Spector suspected he could know something critical. When the Avatar found him in prison, Oaxtepac told how one day the invulnerable Dr. Spector had come into the city and made Huitlapacti king, forcing Moctapotl into exile. After the usurper was lynched by the people, Oaxtepac was freed and returned to his position as shaman at Moctapotl's side.
