Fake Namek is a planet that only appeared in the anime. Its disguised appearance has green sky and lakes like the real Namek, but also deserts, forests, caves, and castles. Its true appearance is a dark, cloudy area full of man-eating monsters. Raiti and Zaacro were trapped on the planet. A fog around the planet makes it inescapable unless the Stellar Winds are near.
