Brainstorm has a crab-like appearance. He has 2 claws on each arm and 6 legs on each side. 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.
Aside from a heightened intellect, Brainstorm can manipulate electricity and project force fields around himself and others through thought, by opening the 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. With a simple thought, Brainstorm is able to conjure up storms. His sturdy shell gives him extra durability. He also has the ability to control to change certain technology 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 also 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 gave Brainstorm a headache and makes it hard for him to concentra. 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, and Brainstorm's electric blasts can be grounded. A weak spot is at his brain, when struck, he experiences excruciating and unbearable pain. In Pier Pressure, Brainstorm had difficulty opening portable toilet door because of his pincers.Ultimate warrior to mujhe messages bahut garmi I am happy to make ndI
Like Ultimate Echo Echo and Big Chill, Clockwork, and Lodestar, Brainstorm also has a mouth that doesn't move except to show emotion, in War of the Worlds: Part 2, it opened when he vomited and in Vilgax Attacks, it opens and closes depending on his motion.
Brainstorm has had only two appearances in a video game, while the other original 10 have had 3 appearances.
Unlike Benvicktor and Buzzshock, Brainstorm's lightning is not green. Instead, it's yellow, except in Voided, where the lightning was blue.
