Professor Screweyes

Professor Screweyes is the main antagonist in We're Back: A Dinosaur's Story. He is Captain Neweyes' evil brother and head of the dark circus. He is also the inventor of Brain Drain, which drains the intelligence of, and probably devolves, anyone who uses it. His name comes from the screw that replaces his left eye.

In the film, the two children protagonist wish to join his circus not knowing the evil behind it. They eventually find it in Central Park and meet Professor Screweyes. With slight manipulation, he gets the children to sign a contract in blood. The dinosaurs arrive to save them. Once he notices the dinosaurs he is delighted. He thinks they will be the perfect attraction for his horror circus. He demonstrates his power of his invention, the Brain Drain, on the children which turns them into dim-witted ape-men. Screweyes makes a deal with the dinosaurs; if they take the Brain Drain and become the main attraction in his circus, he'll revert the children back to their normal selves. The dinosaurs accept his offer and are turned back into their natural instinct driven state of mind.

When the children awake the next morning and see the dinosaurs, they form a plan to sneak into Screweyes' circus and rescue them.

After several frightening shows of holograms, lights, and people in suits, Screweyes personally introduces his "main attraction". The dinosaurs are rolled in, chained up on a large cart. Screweyes moves to the Tyrannosaurus Rex's, leg and touches it which terrifies the audience. Screweyes laughs and claims he has no fear but soon after he says this, Rex breaks free of his chains and attacks the fearful Professor. Rex is stopped however by Louie who is able to revert him back to his intelligent state by pleaing to his true nature and hugging him. The same effort reverts the rest of the dinosaurs back to normal.

Screweyes is furious when the audience is not scared but happy. His brother, Captain Neweyes, then arrives to take the dinosaurs and the children home. Screweyes' clown named Stubbs arrives to quit and humiliates Screweyes in the process.

Neweyes offers Screweyes a chance to come with him on his aircraft but he refuses. At that, Neweyes flies away with the dinosaurs and children. With the audience gone, Screweyes is left alone in the darkness with only the crows for company. He admits out loud that he is afraid of being alone and screams as the crows frenzy around him, presumably consuming him, leaving only his screw eye which is carried away by a crow.
