Tremendous Jackson is a professional baseball player who only appeared in the episode "The Retroville 9". He appears to be a fan of Ultra Lord, as he makes multiple references to him when speaking to Sheen. He speaks of the long hours that it takes to become good at baseball and is very ashamed in the team when it is revealed that they were not nearly as good as they appeared without Jimmy's inventions.


  • He is a spoof of Bo Jackson.
