Bullfrag

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

Appearance
Bullfrag is a humanoid frog-like alien with three-fingered hands and two-toed feet. He is, however, considerably taller and more muscular than a typical Incursean. He 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 other transformations. In this outfit, Bullfrag's sunglasses are green, the bodysuit now has a green stripe down the middle, he 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
Bullfrag has powerful jumping abilities, and is very agile.

Bullfrag's physique makes him stronger and more durable than an average Incursean. He has impressive hand-to-hand combat abilities.

Bullfrag possesses a long, sticky and prehensile tongue, which he can use as a grappling line or to hit a distant target. It is also very strong, able to smash boxes.

Bullfrag can inflate his chest to repel enemies and gain momentum to jump.

Weaknesses
Like all Incurseans, Bullfrag is weak to a strong smell.

Bullfrag's tongue hurts if it stretches too long.
