Cerebrocrustaceans (a play on "cerebrum" and "crustacean") are crab-like aliens from the stormy planet Encephalonus IV.


The Cerebrocrustaceans are crab-like aliens with orange or purple exoskeletons with small bumps around the face and on top of their head. Their head is very large with arms sprouting from each side. They use a neck brace to support their heads while moving out of the water, have claws, six spider-like legs and a stubby body. Their face is composed of only yellow or pink eyes and a mouth (which does not move as they speak, because they communicate through electrostatics vibrating gaseous media and liquid).

History Edit

The Cerebrocrustaceans' ancestors took advantage of the natural storms surrounding the Encephalonus planets, resulting in the destruction of three planets by using up all of their natural resources.

By the time they arrived at Encephalonus IV, the Cerebrocrustaceans had evolved to create the electricity instead of taking it away and therefore arrived as the electricity generating crustaceans you now see.

The Cerebrocustaceans are deeply ashamed of their ancestors being responsible for the destruction of their original homeworld Encephalonus I and the two other planets (Encephalonus II and Encephalonus III) in their solar system.

Powers and AbilitiesEdit

Cerebrosrustaceans are able to produce electrical storms, generate and shoot electricity at foes and psychic forcefields from their brain. They can also encase other people in force-fields and move them around.

Cerebrocrustaceans are extremely intelligent, making them speak in a higher diction and a British or Swedish accent. However, they tend to be egotistical, which makes them forget how to do simple things due to their cocky attitude.


Their predators are the Vicetopus, aliens that resemble large, dark red octopi.

Omnitrix Transformation Edit

The Omnitrix's Cerebrocrustacean representative is named Brainstorm, who first appeared in the Alien Force episode "Pier Pressure". Brainstorm has appeared in almost every subsequent series except the reboot.

Brainstorm has also been used by Albedo.


Notes Edit

  • They are rivals of the Galvans.
  • According to Derrick J. Wyatt, Cerebrocrustaceans are filter feeders and can project their thoughts with soundwaves.
  • According to Duncan Rouleau, the Omnitrix from the Ben 10 reboot contains Cerebrocrustacean DNA. Therefore, Brainstorm is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
