Zorak

Zorak is a giant, praying mantis-like alien, who is the arch nemesis of the intergalactic hero, Space Ghost. Zorak has decimated entire planets, and is a ruthless warlord.

After being kidnapped by Space Ghost, Zorak, along with Moltar and Brak were forced into assisting on Space Ghost's talk show, Coast to Coast, and his sketch comedy show, Cartoon Planet.

Zorak is probably best friends with Brak.
