Antimatter

Appearance
Antimatter appears to be a collection of transparent shapes, including a purple, green, and yellow triangle as well as a pink/red jagged shape. They're the only character with a jagged mouth.

Personality
Antimatter is shown to be somewhat snooty, and can also get cocky sometimes. Antimatter is also the second most-powerful character (behind Oodle) and the most powerful contestant. They say they can "essentially do anything" and how they "exist everywhere known in the universe". They also have the ability to shrink themselves into the size of an atom.
