– Stinkfly to the Leader Alien.[1]

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 three clawed fingers. He has four pedunculated eyes that are pretty small. These eyes are linked directly to the sides of his huge head. His wings are light green and very fragile with lines on them, and his limbs are a brown-greenish color. His tail is an ultra sensitive receptor, making it like an antenna.[pop-up 1][2]

In the original series, Stinkfly wore a white sleeveless jumpsuit with black lining which covered most of his body including his head and tail, his hands had a black coloration similar to fingerless gloves, and his eyes were yellowish-orange. He wore the Omnitrix symbol on the top of his forehead.

In A Change of Face, Stinkfly wore a black hat.

In Don't Drink the Water, 4-year-old Stinkfly (dubbed Stinkyfly) has a smaller body and pupils in his eyes.

In Ultimate Alien, Stinkfly's eyes were recolored green and his hands were the same color as his limbs. 16-year-old Stinkfly wore the Ultimatrix symbol on his chest in the Ultimate Alien intro, though it was on his forehead in Heroes United.

In The Forge of Creation, 10-year-old Stinkfly looked the same as in the original series, except his eyes and Omnitrix symbol were recolored green and his hands were the same color as his limbs.

In Omniverse, 11-year-old Stinkfly looks mostly the same as in Ultimate Alien but with bigger wings, lighter skin, larger eyes and pupils, a bigger body and tail, and a slightly redesigned stinger. His clothes are white with black stripes and is spread only until his forehead.

16-year-old Stinkfly looks the same as his 11-year-old self, except that he is taller and the white portions of his clothing are recolored green. Much like his younger self, the Omnitrix symbol is located on his forehead.

Kevin as Stinkfly

Kevin's Stinkfly looked the exact same as Ben's did in the original series, but with a darker color scheme and without an Omnitrix symbol.

Ben 10,000 as Stinkfly

Ben 10,000's Stinkfly's body style was almost the same as his 10-year-old self, with the only differences being that his eyes were longer with black pupils, his stinger and legs were larger, and his clothes were in inverted colors similar to Ben 10,000's first outfit.

Powers and Abilities

Stinkfly possesses two 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 eyestalks and mouth. These liquids can be both a flammable toxin or an immobilizing adhesive, instinctively choosing what type of slime it can be.[MW 1]

Besides liquids, Stinkfly can release poisonous and methane gas.[DR 1]

Stinkfly's slime has properties akin to fire extinguishers, meaning that it is capable of putting out fires.[3]

Stinkfly is able to suck up his slime from his mouth to pull himself upwards.[4]

Stinkfly is accompanied by a natural odor-like stink that comes from the oils he secretes to keep his exoskeleton joints moving.[pop-up 2][5]

Stinkfly's black tail is extremely sharp with a stinger-like end that can tear and rend through steel almost effortlessly.[6]

Stinkfly's exoskeletal body is fairly strong, allowing him to survive unscathed while being smashed through buildings and being caught inside a large explosion.[7]

Stinkfly possesses enhanced dexterity, being able to operate a cell phone with his three-fingered hands.[8]

Stinkfly has great strength in proportion to his body, being able to carry heavy loads while maintaining steady flight.[9] He could even still fly while Vilgax was hanging on his tail end, barely being weighed down by the latter's immense size and weight.[7]

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.

Stinkfly's claws and sharp-pointed legs allow him to cling onto solid surfaces.

As a toddler, Stinkfly was able to emit a powerful herbicide via flatulation, which is capable of killing plant-like creatures.[10]


A more minor inconvenience is Stinkfly's odor, which can be a problem if he is trying to hide from anything or anyone that can smell.

Although his exoskeleton body is fairly strong, Stinkfly's wings are very fragile. Water is especially a problem for him, as it can render him incapable of flight if he gets too much on his wings.[4][11] Furthermore, he cannot swim very well due to the small surface area of his limbs.

Stinkfly seemed to have trouble carrying an overweight Max while flying to the temple of Ek Chuaj,[12] meaning that he may only be able to carry very heavy things for a short time.

Stinkfly can be tied in place by his tail.[13]

Stinkfly is vulnerable against electricity, as shown when he was shocked trying to attack Phil as Terroranchula.[14]

Being a Lepidopterran, Stinkfly's goo can be neutralized by the fog of his natural predator, the Buglizard.[15][14]
