Stinkfly is the Omnitrix's DNA sample of a Lepidopterran from the planet Lepidopterra in the Delta Dimension of Earth-1010.


Stinkfly has a slender, humanoid body. His body is mostly blue, but his shoulders, armpits and ankles are light blue, while his chest, abdomen, neck and the lower part of his face are cyan. He has three blue fingers on each of his hands and two-toed dark cyan feet. He has greenish blue eyes. He has two bright orange wings on his back. The Omnitrix dial is on his chest.

Powers and Abilities

Stinkfly's wings afford him quick and agile flight. He can change direction mid-air rapidly.

Stinkfly can excrete high pressured streams of some green viscous liquid or methane gas from two ducts located inside of his shoulders. These liquids are both flammable and an immobilizing adhesive.

Stinkfly seems to be able to carry heavy loads while still flying as normal.

The light-cyan part of Stinkfly's exoskeleton glow in the dark.


Stinkfly is vulnerable to poisonous gasses, including his own.

Although his exoskeleton is strong, his lace wings are fragile. Water also proves problematic as it renders him unable to fly.

A more minor inconvenience is Stinkfly's odour, so hiding from anything or anyone that can smell can be a problem. Additionally, his bioluminescence is not consciously controlled and cannot be turned off.

Stinkfly's flammable gases can be used against him if he is inside them.


Ben 10: Reboot Revolution

Stinkfly was first used by Ben Prime while wielding the Delta Omnitrix in Chapter 3. He flew from the crashed truck over to the Rustbucket, to meet Timekiller on the roof. Ben later learnt that this alien was Stinkfly after firing goo from his shoulders.
