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, as a first opportunity to show off his superior intellect.

== 	Abilities ==

Brainstorm has 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 is extremely intelligent but it is never revealed if he can rival Galvans (although, it has been hinted at in the Season 2 finale, when Azmuth and Brainstorm argue over who is more intellgent). Due to their extreme intelligence, he can possibly build almost anything out of spare parts. He also has the power to levitate, and create electricity from his pincers without needing to open his skullplates as well. He may be extra durable due to his shell.

==	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 intelligent 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.thumb|300px|right

==	Ultimate Alien==

Brainstorm reappear in the Ben 10: Ultimate Alien episode, Escape From Aggregor, facing the yeti controlled by Dr. Animo. He is able to turn the yeti against Animo by re-wiring the mind-control device on him and makes it attack him.
