Stinkfly

Stinkfly is the Omnitrix's DNA sample of a Lepidopterran from the planet Lepidopterra.

Ben as Stinkfly
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.

In Ultimate Alien, Stinkfly's Ultimatrix symbol is on his chest, his eyes are green and he no longer wears gloves. Ten year old Stinkfly looks exactly like his 16 year old appearance except his Omnitrix symbol remains on his forehead.

In Omniverse, Stinkfly has bigger wings and his clothes are spread only till his forehead. He has lighter skin, the Omnitrix has returned to his forehead, he now has bigger eyes and pupils, and his body and tail are bigger. Sixteen year-old Stinkfly has green clothing while eleven year-old Stinkfly has white clothing. Just like in Ultimate Alien, he no longer has gloves and his tail and body look bigger.

Ben 10,000 as Stinkfly
Stinkfly's body style is almost the same as in the original series, with the only differences being that his eyes are longer and have black pupils, his stinger and legs are larger, and his clothes are inverted, similarly to Ben 10,000's.

Powers and Abilities
Stinkfly possesses four insectoid wings that allow quick and agile flying, and can change directions at exceptional paces.

Stinkfly can excrete high pressured streams of liquid from the pollen ducts located inside of his eye stalks and mouth. These liquids have a vast range of forms, from a flammable toxin to an immobilizing jelly.

In Don't Drink the Water, four year old Stinkfly (dubbed Stinkyfly) was able to emit a powerful herbicide via flatulation.

Stinkfly's black tail is extremely sharp and can slice through steel with little effort.

Stinkfly has great strength in proportion to his body, able to carry heavy loads while maintaining steady flight.

Stinkfly has 360 degree vision as he is able to move two eyes at the back of his head and keep the other two eyes at the front of his head.

Weaknesses
Stinkfly is extremely weak to any kind of chemical, poison, or gas.

Although his exoskeleton body is fairly strong, Stinkfly's wings are very fragile. Water is especially a problem for Stinkfly, as it can render him incapable of flight if too much gets on his wings. Furthermore, he is unable to swim due to the small surface area of his limbs.

A more minor inconvenience is Stinkfly's odor, so hiding from anything or anyone that can smell can be a problem.

Stinkfly's goo can be neutralized by Buglizard's fog.
