Brain Squid is the Knock Off Omnitrix's DNA sample of a Brain Eater Mimic in Ben 10: Haunted.
Brain Squid resembles a Brain with an eyestalk surrounded in a protective goo. He has four tentacles as his feet.
Ghost King's Ectoplasm encases him as his feet morph and split. His eyes vanish and are replaced by a singular eyestalk on his head. Finally his body morphs as the transformation ends.
Powers and Abilities
Brain Squid's main power is to mimic the Brain Eaters, a feared apex species through out the cosmos.
Brain Eater can use his protective goo to fight opponents if needed. This is done by focusing it into extra limbs.
He is Highly Intelligent, since his kind was able to learn to mimic an apex predator to survive.
Brain Squid is only a mimic. If the trick is revealed, it's pretty much game over.
He debuts in Every Alien Has A Use. Here, he scares off Vulkanus and Trumbipulor since they think he's a real Brain Eater.
He returns in War of the Villains: Where he scares off multiple foes just by standing there. Gar Skuther informs him of what he is before V. V. Argost overhears and attacks, not afraid of losing his brain after learning the truth.
