Uh, ah...What can I do? I gotta have something going for me other than the power of cuteness.

– Ball Weevil before figuring out his powers.[1]

Ball Weevil (alternatively spelled as Ballweevil)[2] is the Omnitrix's DNA sample of an unknown species from Atrocius 0.


Ball Weevil is a small yellow insect-like alien with black eyes and green pupils. He has four stick legs and a beak along with a big antenna.

Ball Weevil wears the Omnitrix symbol on a green and white brace around his neck.

Powers and Abilities

Eat exploding gummy ball thing!

– Ball Weevil to Tyrannopede.[3]

Ball Weevil can spit round, green, sticky balls of plasma[4][5][note 1] that absorb matter and explode upon impact, or whenever Ball Weevil wants it to.[7] The size of these balls depends on how much matter they absorb.

Ball Weevil's plasma balls can be in more shapes than just spheres. The bigger the ball he creates, the larger the explosion.

Ball Weevil can spew out plasma in a controllable stream to act as a rope to tie up an enemy. The plasma is strong enough to momentarily hold a Tetramand.[7]

Ball Weevil's plasma balls can absorb energy, as seen when he absorbed both a Prypiatosian-B's radioactive energy blasts and an Aerophibian's neuroshock blasts into one of his globules.[8]

Ball Weevil has enhanced agility and balance, being able to roll on his plasma balls and can climb on walls with ease.

Ball Weevil seems to be pretty strong for his size, as shown when he stopped his giant plasma ball rolling at a high speed.[5]

Ball Weevil's plasma balls are buoyant enough to float on water.[DJW 1]


Ball Weevil can be hurt by his own plasma balls if they are reflected at him.[1] He can also get stuck in his own plasma.[7]

Ball Weevil is vulnerable to being trapped by a member of Terroranchula's species, his natural predator.[3]

Ball Weevil's plasma can be neutralized by a Terroranchula's webs.[1] It is also useless against a species capable of withstanding it, such as Arburian Pelarotas.[DJW 2]

Ball Weevil cannot breathe underwater.[DJW 3] He also cannot use his plasma balls as a helmet because he can't breathe in slime.[DJW 4]

While he can absorb matter and energy using his plasma, Ball Weevil cannot absorb gases.[DJW 5]

  1. Alternate versions of Ball Weevil are shown generating plasma in different colors. For example, 17-year-old Mutant Kevin's plasma is colored red.[6]
  2. Considering how Ball Weevil's DNA was already in the Omnitrix, it is implied that he was never locked.[DJW 6]
