Combine Overseer

The Overseers are AI-controlled machines created by the Combine to watch over the ARKs. Once they have been defeated, they will proceed to ascend survivors by transferring survivors to other ARKs. As proven by X123Mini456, the Combine created and used the ARKs as arenas for their own pleasure.

Notes/Trivia

 * In the fanfiction, the Combine had in fact destroyed many worlds by secretly ripping them apart via creating space stations and using them as giant arenas to torture and enslave alien species.
