Augstaka is a planet that is inhabited by the Highbreed.
Augstaka is a regal, welcome-looking planet. It has low-rolling green hills, regal coastlines and clean, busy metropolises.
Before Ben used the Omnitrix to fix and hybridize the Highbreed's DNA, Augstaka looked like a polluted and crumbling wasteland, predominately red in coloration. Afterwards, it was a clean and futuristic metropolis, predominately blue.
Though it looks inviting, no species but the planet's own was allowed to set foot on Augstaka.
'Augstaka' is a Latvian word, meaning 'the highest'.
