Tikhaos

Tikhaos is a fusion entity of the spirit of Tikal bound to the mutated Chao-turned water elemental, Chaos, from the Mobius: X Years Later dimension. Though physically composed of Chaos' water-body when normal, it retains the shape of Tikal as well as some semblance of her personality. Tikhaos exhibits a "hunger" for Chaos energy, possibly to sustain her/its/their form, but when overloaded with it will lose control and transform into the savage water god, Perfect Tikhaos.

Quarantined
Tikhaos was somehow placed in the catacombs deep within Castle Mobius during the rule of King Shadow along with E-107 Theta, and the Anarchy Beryl Bomb, as she was considered a threat to Mobius that had to be quarantined. (SU: #7)

Released from the Catacombs
Shortly after the Five Years of Peace celebration, the former King Shadow was restored from suspended animation by Lien-Da, and proceeded to liberate Tikhaos from her imprisonment. Desperately "hungry" for some chaos energy, Shadow supplied her with an excessive amount of Chaos powers, resulting in the Tikal entity losing control and transforming into Perfect Tikhaos. The monster laid waste to Castle Mobius, and then prepared to confront the Future Freedom Fighters. (SU: #7)
