In the animated series "", Cerebro was featured numerous times. It was shown being used mainly by the Professor and eventually Jean Grey. In the beginning of the series Cerebro was a primitive version of what it would later become as the show progressed eventually taking an appearance identical to the Cerebro in the X-Men films. Cerebro originally appeared as a computer console with custom peripherals that came out of a hidden wall component in the mansion. Eventually, this Cerebro was destroyed by Professor X's evil step-brother the Juggernaut. When it was rebuilt the Cerebro was given its own room, instead of the hidden wall component as before, and looked identical to the designs of Cerebro in the films. Cerebro even came in a portable helmet form for travel and field missions. Jean Grey used this Cerebro to amplify her telepathic powers as she did in the comics and previous series. It even helped boost Jean's telepathic powers in order to battle a possessed Professor X in the series finale. During the fight, Cerebro was shown to unleash the Phoenix within Jean for a split second, eventually gaining the power to defeat the evil Xavier, and return him to normal. In the episode "Fun and Games", Arcade, a student version of one of the X-Men greatest villains, hacked into Cerebro and used it to control the mansion's security system to attack the X-Men believing the program to be a game. However, he made no use of its telepathy-enhancement technology, instead merely rewiring it to allow him access to the security systems.
