Qualopec, one of the triumvirate, the three sacred rulers of Atlantis along with Tihocan and Natla. Together they created the Scion, a device of immeasurable power and the ultimate power source of Atlantis.
Qualopec along with Tihocan both sentenced Natla to eternal imprisonment for misusing her power of the Scion in an attempt to create genetic mutations and for using the army of Atlantis against them. He and Tihocan were present at her incarceration in present day New Mexico, USA. They then sealed her piece of the Scion within the city of Khamoon in a sanctuary. In Anniversary it was revealed that he is actually Natla's brother, and that it was her who caused him his physical inability.
After the destruction of Atlantis, he escaped to Peru, where he presumably tried to re-establish his civilization. The result was the birth of the Incas. He died and was entombed beneath Vilcabamba, the last Incan stronghold city still facing his piece of the Scion, with his guards mummified by his side. The knowledge of this tomb was lost, believed to be somewhere in the Andes Mountains in Peru.
In Anniversary it is also revealed that he was in fact still alive in his tomb, waiting for someone to steal his piece of the scion, however, he was only awakened when the entrance to the throne room collapsed.
His appearance in Tomb Raider shows a disabled being needing artificial appendages to stand up and move around. He has lost the use of his legs, how this happened was not explained in the original game. Anniversary states that Natla (who was his sister) maimed him resulting in his disability. He wears a helmet with a visor covering his face and illuminating his eyes green. His voice activates a luminous display of green flashes by his mouth indicating he uses a device to help him speak. In Anniversary his face is revealed. He wears dark Atlantean garbs with his Scion piece worn around his neck. Anniversary portrays his garbs with more colour and extravagance.
