Atrocian

Atrocians are a small fat blob-like alien species from an unknown planet.

Appearance
Atrocians resemble anthropomorphic potatoes covered in warts with short and stubby limbs. They appear to be mostly yellow in color but can be other colors as well, including pink, blue, purple, and green.

Culture
The Atrocians are unable to clean up after themselves, so their Insectoid neighbors evolved as a natural sanitation solution to the Atrocians' garbage problem.

Powers and Abilities
Atrocians are extremely durable, making them immune to physical and energy attacks, heat, and acid.

Omnitrix Transformation
The Omnitrix's Atrocian representative is named The Worst, who first appeared in the Omniverse episode "Outbreak" when Blukic and Driba tried to repair the Omnitrix. The Worst solely appears in Omniverse.
