Frederick is an astronaut trained at the Middleton Space Center. He was being trained for a year long mission to be spent in the space station. He had a box located on his wrist, so that he can communicate with humans, using human language. He met Kim and Ron on the day for the Rocket Boosters to be at the space center. Frederick hugged Ron, and Ron had Rufus detached himself from Frederick. Monkey Fist believed that Frederick was the "Brightest Monkey," and was determined to go into space with him. Frederick was able to exit the rocket, before the rocket ever left the space center.
