Brainstorm

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

Ben as Brainstorm
Brainstorm has a crab-like appearance. He has pincers for hands and six legs. He can open his skull plates at will to reveal his brain, which is pink in color.

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

In Omniverse, Brainstorm has a black loin cloth with a green stripe running across it on the bottom of his body. He has a black stripe in the center of his head with a green stripe in the center of it. He now has 4 legs instead of 6 and each leg has a black stripe on its joint. He wears the Omnitrix symbol on a white and green neck brace. The hair-like spikes on his face and forehead are longer and his eyes connect to a large black strip that extends around his forehead. Brainstorm now has two spikes on each elbow.

Albedo as Negative Brainstorm
In Ultimate Alien and Vilgax Attacks, Negative Brainstorm is similar to Ben's, but his eyes and the Omnitrix symbol are red.

In Omniverse, Negative Brainstorm looks just like Ben's Brainstorm in Omniverse, but he is pale pink in color with yellowish teeth and his stripes are red instead of green. He wears the Ultimatrix symbol on a red and white neck brace.

Powers and Abilities
Brainstorm's cranium holds an immense brain, giving him super-massive intelligence. He can solve difficult calculations mentally in roughly seconds. As seen in Greetings from Techadon, he knows complex angular physics, and can visualize equations and movement of objects as if they're actually there. He can determine mechanical values and physical properties simply by looking at them.

Brainstorm can produce and manipulate green electricity (yellow in Alien Force and Ultimate Alien) in a variety of useful forms, including shoving or launching enemies, shocking enemies, creating protective coatings, and creating force fields of energy, by opening the exoskeleton plates on his skull.

As shown in Vilgax Attacks, Brainstorm can launch energy bolts and create large energy blasts. He can uses his electrokinesis to telekinetically move objects, size and mass ranging from trains to living beings. He can generate electricity in his pincers without needing to open his skull plates. He can control machinery and similar things using his electrokinesis, giving him a form of technokinesis.

Brainstorm is strong enough to crush a refrigerator using his pincers. Brainstorm is also able to climb walls.

In Inferno, Brainstorm displays the ability to levitate above the ground.

He can make exactly correct movement as he desire.

Weaknesses
Echo Echo's sonic screams can give Brainstorm a headache and it 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, as seen in Vengeance of Vilgax: Part 2, when he was too busy planning an attack on an escaped Spidermonkey before he remembers to scan him.

If his shell is closed when releasing electricity, it will shock and injure his brain.

It seems Brainstorm can be shorted out due to the electricity in his brain.

Since he is a Cerebrocrustacean, he is vulnerable to his species' natural predator, the Vicetopus.
