Atrocian

Atrocians are a blob-like alien species originally from Atrocius 0 before the planet was abandoned thousands of years ago.

Anatomy
Atrocians resemble anthropomorphic potatoes covered in warts with short and stubby limbs.

Although they traditionally have yellow skin, Atrocians can come in other colors. For example, Pink-Worst has pink skin, Blue-Worst has blue skin, Purple-Worst and Violet-Worst have purple skin, Green-Worst has green skin, and Slim-Worst has orange skin.

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

Weaknesses
Atrocians do not appear to be built for combat, and are effectively punching bags for other beings as a result.

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