“The fun's only just beginning! Ready for round...round...how many- how many are we on?”
― Xenarchy

Xenarchy, or known as Xena, is the mod iteration of Xenophanes (VS. Sonic.EXE) and the main antagonist of the mod, appearing in Too Slow, and upcomingly in You Can't Run and Triple Trouble

He is the Chaos itself and resides in the Sonic the Hedgehog world. As well, he can invade other games worlds, like Kirby, Zelda, Vectormann, etc.

The physical embodiment of Chaos and disorder itself, Xenarchy thrives on Kaoxen (K-o-xen), a bright pink substance that acts as Xenarchy's power source. His main method of attack is anything that comes from his eyes, laser eyes, hypnosis, etcetera. He has since taken over Mobius entirely and is also spreading out to other games as well.
