ITALIANO:Cervellotico è un Cerebrocrostaceo dal pianeta Encefalonus IV (dal prefisso "Encefa-" che indica il cervello). Cervellotico è un crostaceo alieno geniale con l'abilità di controllare l'energia elettrica e proiettare campi di forza intorno a se stesso ed altri tramite il pensiero, cosa che gli riesce aprendo le placche esoscheletriche posto sul suo cranio. Possiede inoltre il potere della levitazione. Cervellotico può generare energia elettrica anche dalle sue chele, senza la necessità di aprire le placche esoscheletriche.

ENGLISH:Brainstorm (voiced by Dee Bradley Baker) is a Cerebrocrustacean (a play on "cerebrum" and "crustacean") from the planet Encephalonus IV (a play on "encepha-", a prefix referring to the brain).^[41] Brainstorm is a genius crustacean alien with the ability to control electrical energy and project force fields around himself and others through thought, accomplished by opening the exoskeleton plates on his skull. He also has the power to levitate. Also, it is shown in "Single-Handed" that he can make electricity from his pincers without needing to open his skullplates, as well. In this form, Ben speaks with much greater diction and with a British accent.

He first appears in "Pier Pressure" to battle Ship. Brainstorm is Ben's first accidental transformation in the new series, and the first alien that Ben thinks up a name for (Ben simply shouts out the names of the other aliens upon using them). However, unlike the accidental transformations in the previous series, this one was caused by the dock shaking and causing the Omnitrix to cycle to Brainstorm instead of Jetray.
