Cerebro is the Omnitrix's DNA sample of a Cerebrocrustacean from the planet Encephalonus IV in Ben 12: Omnitrix Unleashed.


Cerebro is a mint green crab-like alien. He has a large "head" that takes the entirety of his upper torso, his eyes have a red outside, black interior and red pupils. On the top of the head are three plates, which when opened, reveal his brain that is a pinkish-purple color. Cerebro has two arms coming out of his upper body which have pincers, out of his lower body come six legs with spike-like feet. He has spikes scattered around his body, with black joints connecting his limbs together. His uniform is black with red and grey lines. 

The Omnitrix symbol is located on the top plate of his forehead.

Powers and Abilities

  • High Intellect- Cerebro has one of the highest IQ's in the galaxy, inferior to nothing but a Galvan. His brain is more strategic than others, allowing him to quickly determine how to defeat his foes.
  • Electricity Generation- Cerebro's brain can generate enough electricity to be utilized as a strong attack. 
  • Electromagnetic Levitation- Using the electrical currents in the air, Cerebro can levitate and gain the higher ground against an opponent.
  • Force-Field Generation- Cerebro can create a protective barrier made of energy. 
  • Underwater and Land Survivability- Cerebro can breath underwater because he has gills, but he can survive on land because his gills keep him moist when on land. 
  • Mnemokinesis- Cerebro can alter or erase people's memories or thoughts by controlling their brain pulsations.


  • Fragile Brain- If someone manages to hit him in the brain while exposed, it can cause severe pain or even death.
