Diegel is a power-type Zoanoid that seems to resemble a humanoid boar. Created by Cronos's USA branch, Diegel was designed both for fierce combat and infiltration. Unlike other Zoanoid types, Diegel's Zoanoid genome is indistinguishable from un-optimized humans, meaning a Diegel in its human form would be able to slip past the early warning systems of anti-Cronos groups and breach their bases and facilities.

Diegel possesses 15 times the strength of a normal human and uses the razor-sharp quills on its back to viciously maim its enemies.
