Amp is the team's so-called "space cadet" who became the band's bass player after revealing to the gang that his brother (who was originally intended to join them instead of Amp) was going back to college.
His intelligence was curious, as he was either clueless to his surroundings, or displayed unusual intellect. Amp had an unorthodox way of performing tasks, such as writing in a notebook using his toes, or studying by eating book pages with milk and sugar. All the weirdness is explained when revealed that Amp is really an alien and returns to his own planet with his parents offscreen.
To enter Syberspace, he always used a different phrase to be humorous. Amp's uniform consisted of a helicopter helmet and leather jacket.
