1st appearance: {{{first-appearance}}}

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


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

Powers and AbilitiesEdit

Aside from a heightened intellect, Brainstorm can control electrical energy and project force fields around himself and others through thought, by opening the exoskeleton plates on his skull. He also can use his lightning to telekinetically move objects, ranging from trains to even people and create electricity from his pincers without needing to open his skull plates, he can also cause a storm just by thinking. He may be extra durable due to his shell. His pincers might be sharp enough to cut things. Brainstorm is also adept at back flips. He also has the ability to control machinery (In a unique use of his electricity Brainstorm is capable of rewriting electronics by making contact with his electricity.). He is also able to control various aspects of his electricity ranging from a pushing, to shocking, to protective coatings. Brainstorm is able to breathe underwater as the belt on his body is used to hold his head up and help him breathe outside water. He can also make mental calculations like finding the best possible outcome.


Echo Echo's sonic blasts give Brainstorm a headache and makes it hard for him to concentrate (suggesting concentration is required for him to use his powers). Brainstorm tends to be egotistical which makes him forget to do simple things. He also tend to use large, scientific terms that may not be understood by those he's talking to. Sometimes, because of talking too much, he sometimes forgets that he's in the middle of a fight. Brainstorm does not have good movement with his crab legs. Brainstorm's electric blasts can be grounded. A weak spot is at his brain, when struck, he experiences excruciating and unbearable pain. Despite that, Dwayne has stated that his brain is not his greatest weakness. In Pier Pressure, Brainstorm had difficulty opening portable toilet door because of his pincers.
