Voxai Colony Alpha

Voxai Colony Alpha (shortened as "Colony Alpha") is the second to last stage of Sonic Chronicles: The Dark Brotherhood. This is where the Overmind is fought.

History
After gaining a mental passcode from Thelxe in Voxai Colony Beta, Sonic and his group went to Voxai Colony Alpha. After solving a puzzle, Sonic and friends a small area where the Overmind was waiting for them. But, once there, Sonic's group (excluding Sonic and optionally Omega, Big, and Cream) fell under the Overmind's mind control and uttered a brainwashed line (though Knuckles says that he "Must. Protect. Overmind." instead of his mind). Over confident, the Overmind gave Sonic his friends but, which proved to be their downfall. Thebes from Colony Beta came to congratulate the group and discovered that he should take over as Overmind. Colonies Alpha and Beta later helped the Zoah colony find a weak point in Nocturne's deflector shield so they could fire a missile with N'rrgal drones in it to make a small hole so the Cyclone could make it through.
