Ben as Stinkfly Edit
Stinkfly has a bug/insect body and four insect-like flat legs with two arms, whose hands are human-style ones with a black coloration, similar to fingerless gloves, and has three clawed fingers. He has four pedunculated eyes that are pretty small and yellowish-orange in color. These eyes are linked directly to the sides of his huge black head. His wings are very fragile with lines on them. His limbs are a brown-greenish color and his wings are light green. Stinkfly wears the Omnitrix symbol on the top of his forehead.
