Big Bug is the Omnitrix's DNA sample of a Lepidopterran from the planet Lepidopterra and the Dimension 23 equivalent of Stinkfly.


Big Bug looks identical to Stinkfly in Omniverse but he has a different color scheme. His skin is light purple, his wings are white and his pupils are light blue. His outfit is blue and the black parts have dark blue highlights instead of dark green. The rim of the Omnitrix is golden and its energy is light blue.

Powers and Abilities

  • Slime Projectiles
  • Flight
  • Enhanced Dexterity

Big Bug possesses four insectoid wings that allow quick and agile flying, and can change directions at exceptional paces.

Big Bug 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, enough for him to swing from it by his mouth.[1]

Big Bug's slime has properties akin to fire extinguishers, meaning that it is capable of putting out fires.[2] His slime is also immune to being exploited and controlled by Polymorphs.[DJW 1]

Big Bug is accompanied by a natural odor-like stink that comes from the oils he secretes to keep his exoskeleton joints moving.[pop-up 1][3]

Big Bug's black tail is extremely sharp with a stinger-like end that can tear and rend through steel almost effortlessly.[4]

Big Bug's exoskeletal body is fairly strong, allowing him to survive unscathed while being smashed through buildings and being caught inside a large explosion, as demonstrated by Stinkfly.

Big Bug possesses enhanced dexterity, being able to operate a cell phone with his three-fingered hands.[5]

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

Big Bug 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.

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


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

Big Bug is extremely weak to any kind of chemical, poison, or gas.

Although his exoskeleton body is fairly strong, Big Bug'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.[1][6] 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,[7] meaning that Big Bug may only be able to carry very heavy things for a short time.

Big Bug can be tied in place by his tail.[8]

Big Bug is vulnerable against electricity, as shown when Stinkfly was shocked trying to attack Phil as Terroranchula.[9]

Being a Lepidopterran, Big Bug's goo can be neutralized by the fog of his natural predator, the Buglizard.[10][9]
