Tikhaos is a fusion entity of the spirit of Tikal bound to the water elemental, Chaos, from the Light Mobius dimension. Though physically composed of Chaos' water-body when normal, she/it/they 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. She also dislikes being called "Tikhaos".
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). Perfect Tikhaos went on a rampage and began attacking Portal. Lara-Su instructed Jacques and Belle D'Coolette to keep it from going forward with a frontal assault while Melody and Skye Prower distracted it. In the meantime, Lara-Su planned to perform the "Tikal's Prayer" ritual to calm down Tikhaos, while King Sonic went to rescue his family and Silver from the castle's ruins. Eventually, Tikhaos was subdued by the combined might of the Future Freedom Fighters, with the final blow being from Sonia and Manik Acorn, and reverted to her Tikal-based form.
- In an Off-Panel, Lara-Su states that Tikhaos came into being when Tikal performed a cannonball into a pool and Chaos was right under her. But she then said, "At least, that's what my dad told me".
