Stinkfly's primary ability is to squirt high-pressured streams of green, slimy liquid from the glands located inside of his eyestalks and mouth. This slime is strong enough to hold a helicopter and hold down Crabdozer. Stinkfly is capable of utilizing his slime in a number of useful capacities, such as ensnaring his opponents, or blasting a stream of it out of his mouth, solid enough to pull himself upwards like a makeshift grappling hook.
Stinkfly can produce slime of differing properties, and he can instinctively choose which type of slime to expel. Examples include an immobilizing adhesive and a flammable toxin.
Stinkfly possesses two dragon-shaped insectoid wings that allow quick and agile flying and can change directions at exceptional paces.
Stinkfly's black tail is extremely sharp with a stinger-like end that can tear and rend through steel almost effortlessly. His tail is an ultra sensitive receptor, making it like an antenna. Stinkfly's claws and sharp-pointed legs allow him to cling onto solid surfaces.
Stinkfly has great strength in proportion to his body, being able to carry heavy loads while maintaining steady flight. His carrying power comes to its limit when holding something very heavy, shown when he could keep flying while Vilgax was holding onto him.
Stinkfly's exoskeletal body is fairly strong, allowing him to survive unscathed while being smashed through buildings and being caught inside a large explosion.
The flexible nature of Stinkfly's eyestalks give him 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 is accompanied by a natural odor-like stink that comes from the oils he secretes to keep his exoskeleton joints moving.
Stinkfly is capable of releasing toxic gas and methane gas, the former of which was used to kill plant-like creatures.
