Brainbiter reveals that he had already perfected time travel and he also has a neuro-transmitter which controls the animals. He wants Speed to help him get the mineral he travelled nine million years to get, synaptum. It is the key ingredient to Brainbiter's new invention, the Mentor. The Mentor will be able to control the minds of every human on the planet. Speed agrees to participate to keep Racer X from being eaten by a dinosaur.
Speed fills a container with the glowing synaptum.
As Brainbiter fills the mentor machine with the synaptum, Racer X appears. He pulled the mind control from the tyrannosaurus and got away. But Brainbiter uses the Mentor on Racer X and orders him to destroy Speed Racer. His mindless repetition of meaningless phrases makes him sound like a twelve step grouper. Meanwhile, forward into the 20th century, Brainbiter is raising havoc with the brontosaurus he's riding.
