Long ago, Pachacamac led his clan on a series of conquests by attacking other countries, where they committed acts like plundering and hurting the innocent. Eventually, Pachacamac sat his eyes on the seven Chaos Emeralds that resided at the shrine for some Chao and decided to steal them to gain power. However, he faced opposition from Tikal, who had had enough of her father's warmongering ways. When Tikal tried to talk him out of his plans, Pachacamac insisted that the Chaos Emeralds' power was needed for the good of their people.
Despite Tikal's pleas for a peaceful alternative, Pachacamac launched an attack on the Chaos Emeralds' shrine with his warriors. As they were on the verge of getting the Chaos Emeralds, Tikal stood in the way. Pachacamac told Tikal that they needed the Chaos Emeralds' power for the clan's own welfare, but Tikal refused to him go through with it. Standing by the clan's choice and not interested in wasting time on Tikal, Pachacamac ordered his warriors to storm the shrine, trampling over Tikal and the Chao in the process. When Pachacamac reached the Chaos Emeralds, Chaos appeared before him and his men, furious at them for harming the Chao. Pachacamac was then enveloped in energy as Chaos used the Chaos Emeralds to transform into Perfect Chaos, and was seemingly vaporized.
Pachacamac was shown to be a cruel, power-hungry and greedy warmonger, and would justify his acts of war by claiming that it was for the good of his clan. He held little fatherly love towards Tikal, willing to order his warriors to trample over her to get what he wanted.
