Bullfrag

Bullfrag is the Omnitrix's DNA sample of an Incursean from an unknown planet.

Appearance
Being an Incursean, Bullfrag is a humanoid frog-like alien with 3-fingered hands and 2-toed feet. He is, however, considerably taller and more muscular than a typical Incursean, has a more defined jawline, and wears sunglasses. His skin is also paler than a normal Incursean.

Bullfrag debuted wearing a typical black-and-purple Incursean uniform as a disguise, but he also has an outfit that adapts to Ben's clothes, like all of his transformations. In this outfit, Bullfrag's sunglasses are green, the bodysuit now has a green stripe down the middle, he now has fingerless   black gloves and toeless black boots with green cuffs above them, and a green belt with a white buckle.

Bullfrag wears the Omnitrix symbol on his upper chest, which is hidden under his suit while wearing the normal Incursean uniform.

Powers and Abilities
Being an Incursean, Bullfrag has a long, sticky tongue, has powerful jumping abilities, and is very agile.

Bullfrag's physique makes him stronger than an average Incursean.

He has a helmet like the other Incurseans.

Weaknesses
Being an Incursean, Bullfrag is sensitive to strong smells, which could cause him to pass out.

Bullfrag is attracted to Attea, which Ben blames on Bullfrag's Incursean DNA.
