Brainstorm

Brainstorm is a Cerebrocrustacean alien from the planet Encephalonus IV.

Ben first transformed into Brainstorm during the episode Pier Pressure when he had to fight a Galvanic Mechomorph.

Ben first selected to transform into Jetray but it switched to Brainstorm after the pier shook, which makes Brainstorm the first accidental transformation in the series. Brainstorm is also the only alien in Alien Force to not have his name shouted out, as Ben had to think about it first before adopting the "Nom de guerre," (War Name,) Brainstorm.

Abilities
Brainstorm has the abilities to shoot electric storms, and generate force fields. They are extremely intelligent but it is never revealed if they rival a Galvan. Due to their extreme intelligence, they can possibly build almost anything out of spare parts.

Weaknesses
In the episode Good Copy, Bad Copy, Albedo turned into Echo Echo and Ben turned into Brainstorm. Echo Echo's sonic blasts gave 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. They also tend to use large, scientific or intellgent terms that may not be understood by those they're talking to.

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