Overkill appears to be a black colored version of Bonecrusher. His Omnitrix symbol is on his right shoulder instead, while his eye sockets are pitch black and empty. Unlike Bonecrusher, Overkill seems to be surrounded by black particles which come off his body.

Powers and Abilities

  • Death Touch
    • Death Bolts

Anything biological or biomechanical touching Overkill or within his very close vicinity will instantly die, simple as that. Overkill can also manifest his death energy as death bolts, which can severely weaken any living thing it hits but cannot kill as easily.

  • Enhanced Agility
  • Enhanced Durability

Like other Esqueletan species, Overkill's bones are made from a tough carbon-like material, making him very resistant to damage.

  • Semi-Immortality

Overkill cannot die from either old age or from his species touch due to his species' immortality.


Overkill cannot kill any mechanical being or any being without a soul.

Overkill's skeletal body is weak to vibration attacks, which can shatter his bones.

Species Information

Overkill's species are the ancestors to Bonecrusher's, and like Esqueletans are also related to Death Grips' species.

Most Esqueletan Dominuses went extinct after their multiple wars on Espiritu, but some managed to survived in tombs buried underground. Deimios' sample was taken from a surviving ancient Esq. Dominus king, while Ben's was taken from Witheros.
