The Worst is the Omnitrix's DNA sample of an Atrocian from an unknown planet.


The Worst is a yellow, fat, and somewhat "plump" blob-like alien who wears a pair of green underwear with white stripes on it. He has elephant-like feet with three toes and bear-like hands with three claws. He also has wart-like bumps on his forehead and both arms.

The Worst's Omnitrix symbol is located on his belly button.

Powers and Abilities

The Worst can withstand heavy attacks due to his soft, blob-like body.

In It's a Mad, Mad, Mad Ben World: Part 1, it is shown that The Worst can also survive energy attacks, such as Exo-Skull's laser.

The Worst can resist extreme heat.

The Worst can also survive acid.


Although he is indestructible, he still feels pain.

The Worst also lacks any offensive options; basically becoming a punchingbag for any capable enemy.
