The Worst is the Omnitrix's sample of an Atrocian from the same planet as Ball Weevil.


He is a yellow fat blob/globby alien that wears a pair of green underwear with white stripes on it. He has elephant like feet and the Omnitrix is located in his belly button.

Powers and AbilitiesEdit

He can withhstand heavy attacks or in other terms he has enchanced durability.


Outbreak: He made his debut when Blukic and Driba tried to fix the Omnitrix when it malfuctioned. He was later used to defeat Liam, Fistina, Bubble Helmet, and Psyphon along with a group of plumbers.


  • According to Derrick, The Worst has little to no powers while the Omnitrix is malfunctioning. However, he, Pesky Dust, Molestache, and Walkatrout do have powers when the Omnitrix is functioning properly, although these powers may not be practical.
  • He was accidentally unlocked by Driba and Blukic along with Walkatrout, Pesky Dust, and Molestache.
  • He makes a squeaking noise every time he lands on his feet or anywhere on the lower part of his body.
