Cerebrocrustaceans are a crab-like species from the Encephalonus system.


Cerebrocrustaceans closely resemble giant crabs.

Cerebrocrustaceans have red/brown exoskeletons with small spikes around their face and on the top of their head.

Cerebrocrustaceans come in other "crabby colors".[DJW 1]

A Cerebrocrustacean's head is very large, with arms sprouting from each side.

Cerebrocrustaceans have claws, four/six spider-like legs and a stubby torso.

A Cerebrocrustacean's face is composed of only eyes and a mouth.

Only male Cerebrocrustaceans have been seen so far, so it is unknown what female Cerebrocrustaceans look like.


Primitive Cerebrocrustaceans took advantage of the storms surrounding the Encephalonus planets and it in turn resulted in the destruction (by using up all resources) of the planets from Encephalonus to Encephalonus III.

By the time they arrived at Encephalonus IV, Cerebrocrustaceans had evolved in order to create electricity instead of taking it away from the environment.

Modern Cerebrocrustaceans are deeply ashamed of their ancestors being responsible for the destruction of Encephalonus and the two other planets in their solar system.


Cerebrocrustaceans are filter feeders.[DJW 2]

Powers and Abilities

A Cerebrocrustacean's cranium holds an immense brain, giving them super-massive intelligence. They are the third, fourth or fifth smartest beings in the galaxy.[DJW 3] They can solve very difficult calculations mentally in roughly seconds, and can visualize equations and movement of objects as if they're actually there.[1] They can even determine mechanical values and physical properties by simply looking at them.

With their intellect, Cerebrocrustaceans can perfectly understand the mindsets and mannerisms of their enemies, take advantage of weaknesses, and any useful objects around them, so they can know exactly what moves to make to take down their enemies.

Cerebrocrustaceans can produce and manipulate electricity in a variety of ways, such as electrocuting or launching enemies and disabling or destroying machinery, by opening the exoskeleton plates on their skulls. They can also charge up his electrical energy to produce a concentrated beam of electricity strong enough to blast Ship out of the air.[2] Additionally, they can control the voltage of their electrokinetic attacks.[3]

Cerebrocrustaceans can create electric field waves from their brains to block attacks and knock away enemies[4] and generate protective force fields powerful enough to topple an Evolved Arburian Pelarota.[5]

Cerebrocrustaceans can use their electrokinesis to telekinetically move objects, size and mass ranging from trains to living beings without damaging or hurting them.[6] They can also generate and fire electricity from both their pincers and their brains that can control machinery and other technology, giving them a form of technokinesis.

Cerebrocrustaceans are strong enough to pin opponents against walls using their pincers[3] and rip an Arachnichimp's webs off their faces.[7] Their pincers are also sharp enough to stab through metal.[3]

Cerebrocrustaceans are very durable thanks to their shells.[3]

Cerebrocrustaceans seem to have enhanced dexterity, as Brainstorm can use a golf club very easily despite having pincers.[1]

Cerebrocrustaceans are very agile and can perform acrobatics such as somersaults and forward rolls.[8]

Cerebrocrustaceans can scale walls[3] and walk on an Arachnichimp's webs.[7]

Cerebrocrustaceans can levitate several stories above the ground.[6][4]

Cerebcrocrustaceans are capable of breathing underwater[9] thanks to their gills, which they have to keep them moist when they are on land.[DM 1]

A Cerebrocrustacean's shell gives them a protective coat-like layer, which can resist the cold temperatures of places such as mountains.[10]


The sonic screams of a Sonorosian can give Cerebrocrustaceans a headache and make it hard for them to concentrate, suggesting that concentration is required for them to use their powers.[11]

A Cerebrocrustacean's electric attacks are ineffective against weapons that were made specifically for electrokinetic aliens, such as Aggregor's spear.[12]

Though Cerebrocrustaceans can tear it off, they can be immobilized by an Arachnichimp's webbing if they get hit with enough of it.[7]

Cerebrocrustaceans are vulnerable to being trapped by their species' natural predator, Vicetopus, as demonstrated with Dr. Psychobos.[13]

Even though Cerebrocrustaceans can breathe underwater, water can short him out.[14]

If a Cerebrocrustacean's shell is closed when releasing electricity, it will shock and injure their brain, as demonstrated with Dr. Psychobos.[15]

Cerebrocrustaceans are unable to tamper with the thoughts and memories of other beings.[DJW 4]

Notable Cerebrocrustaceans

Notable Mutated Cerebrocrustaceans

Notable Cerebrocrustacean Hybrids


The name Cerebrocrustacean is a portmanteau of "cerebro" (Spanish for brain) and "crustacean".


  • Cerebrocrustaceans project their thoughts as sound waves.[DJW 2]
  • Cerebrocrustaceans do not have a feud with the Galvans over which species is smarter.[DJW 5] Therefore, Dr. Psychobos is the only Cerebrocrustacean that cares.
