Long ago, Tikal was the daughter of Pachacamac, chieftan of the Echidna tribe. She, believing strongly in peace and harmony, was very turned off by the tribe's greed and warful ways. Seeking relinquishment, Tikal felt at peace when at a nearby mysterious temple which held the seven mystical Chaos Emeralds (the servers), and the Master Emerald (the controller). This shrine was also home to the Chao, who lived in peace under the protection of a powerful and trusting force. Tikal had easily made peace with this force, and in return it allowed to play peacefully with the Chao. It was this same barrier that was preventing the Echidna tribe from stealing the seven Emeralds for their own power-hungry purposes.

Tikal did all she could to prevent their full on attack against the shrine, not even the emotion of her cause was enough to sway the decision of her greedy father, who had her, along with many innocent Chao, trampled by his men to clear the seemingly clear path open to harness this emmense power. But then, the shrine's once peaceful and gentle guarding force, now filled with rage and anger as thick as the atmosphere surrounding it, absorbed the power of the Chaos Emeralds, and slaughtered every last one of the Echidnas. Though she hated them, Tikal, barely able to withstand the horror of this meaningless destruction found only one solution. She used the controlling powers of the Master Emerald to seal the guarding force, Chaos, along with her own soul, within the gem's confines.

Much time passed, and eventually the Master Emerlad was shattered open by Dr. Eggman, releasing both Tikal and the still vengeful Chaos. Using her ability to show visions of the past, she assisted our heroes in defeating Chaos, and turning him back into the loving, peaceful creature he once was. Afterwards, they both dissapeared. Where? We may never know.
