Cutter John (last name unknown) is a Vietnam veteran who likes to give Opus and friends a ride on his wheelchair. While doing so they imagine themselves as Star Trek characters aboard the starchair Enterpoop.
First appearance: November 9th, 1981. Last appearance: July 23rd, 1989. Total number of appearances (estimate): 135. Cutter John is based on Saigon John, a character in Breathed's earlier Academia Waltz comic. Curiously, in the first two strips in which he appears, he describes himself as a doctor. This is never referred to again.
