Dr. Spector (full name Johann Schleimann Spector) is a friend of the Avatar on Earth, and as his title suggests, an academic. He also is an archaeologist and adventurer. Spector was thrown to Eodon some time before the Avatar, with his assistant Fritz. He went insane after an encounter in the ancient city of Kotl, starting to have world-conquering plans, which included putting the usurper Huitlapacti on the throne of the Nahuatla Tribe by granting him invulnerability.
