Wabbit

Wabbit is an alien who is free to use.

Appearane
Wabbit's body shape is somewhat similar to Rath in "Heroes United". His chest, feet, and hands are white, his eyes are green, he has a handkerchief tied with his ears that make his long ears down instead of up, he wears gloves similar to Bugs Bunny but fingerles, and the Omnitrix symbol is on his chest. So basically he's a manly bunny rabbit, but with Rath's body shape.

Powers
Wabbit has enhanced strength, agility, has super hearing, has super sonic jumping, can use his buck teeth to chew on anything, and can dig anywhere at incredible speed.

Weakness
Carrots make him sick and weak.
