Atrocians are a small fat blob-like alien species.

Appearance Edit

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


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 AbilitiesEdit

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

Omnitrix Transformation Edit

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.



  • According to Duncan Rouleau, the Omnitrix from the Ben 10 reboot contains Atrocian DNA. Therefore, The Worst is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
