Augstaka

Augstaka is a planet that is inhabited by the Atasians (Self-nicknamed "Highbreed").

Augstaka is a regal, welcome-looking planet that is believed by the Atasians to be the center of the universe. It has low-rolling green hills, regal coastlines, and clean, busy metropolises. Though it looks inviting, no species but the planet's own is allowed to set foot here.

The Atasians/Highbreed believe their DNA is the purest in the universe, and therefore they despise every other species. The Highbreed planet appears in the season 2 finale of Ben 10: Alien Force, War of the Worlds.
