Toepick's Species

Toepick's Species is an unnamed ogre-like species that is considered to be the scariest race in the universe.

Physiology
This species are ogre-like aliens with yellowish-green skin, weed-like spikes on their arms, and pointy fingertips. Their faces are hidden behind metal cages due to how horrifying they look to anyone who sees them face-to-face. According to Derrick J. Wyatt, these faces are supposed to resemble an eldritch horror, despite never being seen onscreen

Powers/Abilities
The faces of this species are so horrifying and hideous that no one can look at them without being scared to the point of turning pale white. The sight of their faces can cause adverse effects including fear, sickness, and madness.

In addition to their face, this species can produce a series of horrifying sounds for extra terror.

According to Wyatt, this species' faces taps into the primordial fears locked in all beings' subconscious and primitive brains. Even Celestialsapien personalities can be frightened by this species.

Weaknesses
According to Wyatt, this species can be scared of their own faces if they look at themselves using a reflective material.

This species is relatively heavy, meaning that they can easily lose balance. They also have below-average reflexes, making it easy for enemies to sneak up on them before they open their cages.

According to Matt Wayne, beings that lack sapient emotion or survival instincts, such as drones and robots, would be immune to this species' fear-inducing abilities. However, it would invoke some sort of defensive reaction from them.

According to Wyatt, the only living being who cannot be scared by this species is Ma Vreedle because "[she has] seen worse".

Omnitrix Transformation
The Omnitrix's representative for this species is named Toepick, who was confirmed to exist in the original series episode "Ken 10" before eventually appearing in the Omniverse episode "Special Delivery". Toepick solely appears in Omniverse.

Toepick has also been used by Ben 10,000 (albeit off-screen).
