Tikhaos is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She 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.
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.
Tikhaos retains the personalities of both Tikal and Chaos, with Tikal's intellect usually in command but with Chaos' desires and emotions bubbling beneath the surface. The combined creature hungers for the Chaos Force, but goes out of control if given too much. Chaos' primal instincts overwhelm Tikal's efforts to reign it in.
Powers and abilities
Tikhaos appears to share many of the abilities of Chaos, but is not quite as powerful, possibly due to Tikal's efforts to control it. It retains Chaos' greatest weakness: its brain. If struck, the pain can disrupt the whole creature's substance. While it feeds on chaos energy, it is also susceptible to having it drained, which Lara-Su accomplished using Tikal's Prayer.
- 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 says, "That's how my dad tells it, at least".
