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, as The Worst was able to withstand several blows from Liam when he was mutated with Vaxasaurian DNA. This durability also made Malice battle him for several hours before passing out in exhaustion.



  • 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".
