Brainstorm

Brainstorm is the Codon Stream's DNA sample of a Cerebrocrustacean from the planet Encephalonus IV. 

Appearance
Brainstorm has a crab-like appearance. He has 2 claws on each arm and 6 legs. He can open his skull plates at will to reveal his brain. He speaks with a British accent. Appearance

Brainstorm wears a neck brace with the Omnitrix/Ultimatrix symbol on it to help him hold up his head and breathe out of water.

In some episodes of Ben 10: Alien Universe, he appears orange. In Back in Action: Alien Universe, his head is more circular, his mouth is smaller, and he appears orange in some appearances, and crimson red in others.

Abilities :
Brainstorm has the abilities of electrokinesis, and generate force fields being able to shield himself and being able to lift objects (Including himself) with telekieisis. They are extremely intelligent, but it is never revealed if they rival the Galvan. Due to their extreme intelligence, he can possibly build almost anything out of spare parts. The top of his head can split open and shoot electric beams. He may be extra durable due to his shell.

Weakness :
Sometimes, because of talking too much, he forgets that he's in the middle of a fight. He does not have good movement with his crab legs.

As shown in Good Copy, Bad Copy, Sonorosians' sound attacks give Brainstorm a headache. Also, the species tends to be egomaniacal which makes them forget how to do simple things as seen in Vengeance of Vilgax where Brainstorm forgot to capture a wild Spidermonkey due to its cocky attitude. He also tends to use large, scientific, or intelligent terms that may not be understood by who he's talking to.

If water is spilled on his brain, shooting electricity will electrocute him, shown by Zynon in Simien 10.
