Before there was WALL-E, Disney’s most famous robot was V.I.N.CENT the robot from Disney’s “The Black Hole.” His name is an acronym for Vital Information Necessary, CENTralized. (Man, that was a stretch.) Although he was essentially a poor-man’s R2D2, he could hover, fight, and even communicate via ESP. He even has his own Wikipedia page.
I hear that if you keep your eyes open during Pixar’s WALL-E you’ll see a robot that is a tribute to Vincent.
