Cottonball is a small, sheep-like alien. His body is covered in cotton/wool which is colored a pale yellow. What his actual body looks like is currently unknown, as all that can be seen of it are his four small feet, and the glow of his ovular, green eyes.
Cottonball wears the Omnitrix symbol underneath his wool, presumable on the chest of his real body.
- Cottonball's body is covered in a cotton-like wool. He can shoot off parts of this cotton as sticky projectiles.
- Cottonball's wool is extremely soft, and also keeps his actual body warm in cold environments.
- Cottonball will sink in water, and also slows down when wet.
- Cottonball's wool can cause him to overheat if he's in an already hot environment.
- If Cottonball somehow loses his wool while in a cold area, his body will be weakened by the cold.
- Cottonball's species is a play on the Latin words "ovium," meaning sheep, and "bombacio," meaning cotton.
- Cottonball's planet name is a play on the Latin words "agri," meaning field (and also short for agriculture), and "lana exunt," meaning wool.
- Cottonball is somewhat inspired by Wooloo from Pokemon: Sword/Shield.
- Cottonball's concept was made by Ethan.
