Stinkfly

Stinkfly is a Lepidopterran alien from the planet Lepidopterra.Stinkfly is Voiced by Dee Bradley Baker

Abilities
In any situation requiring flight, Stinkfly is Ben's alien of choice. Stinkfly's thin, rapidly flapping wings allow him to move at high speeds in the air and dodge attacks just as quickly. Stinkfly also possesses disproportionate strength, enough to carry people and objects heavier than himself. Stinkfly's four eye stalks give him a wide range of vision from the sky, including the ability to look directly behind himself.

For attack, Stinkfly can excrete high-pressure streams of liquids from the pollen ducts in his eye stalks and mouth which inspired Spidermonkey's web shooting. The type of liquid can range from a flammable toxin to an immobilizing jelly. In Don't Drink the Water, Ben's child form of Stinkfly (Stinkyfly) could emit a powerful herbicide gas through flatulation. For melee combat, Stinkfly has a sharp tail and four pincers in its legs.

Weaknesses
Like most insects, Lepidopterrans are extremely vulnerable to any kind of chemical poison or gas. Although their exoskeleton bodies are fairly strong, their wings are extremely fragile and easy to damage. Water is especially a problem for Stinkfly as it can render him incapable of flying if too much of it wets his wings.

Furthermore, he is unable to swim due to the small surface area of his limbs. A more minor inconvenience is Stinkfly's intense body odor (hence the name), so hiding can be a problem when Ben transforms into Stinkfly.

Ultimate Alien
Stinkfly is a confirmed alien. His symbol is now on his chest and his hands are no longer black, his body also appears to have more white and less black on it now.

Possible Future
In Ben 10,000 Stinkfly is bigger, stronger and a lot changed. This alien insect has four large eyes (larger than the one when Ben is ten years old) and has larger legs, especially his two front ones. Stinkfly's stinger is bigger, sharper and makes more damage. His outfit is white with black stripes or other wise and his stinger is white. This is his adult form
