Sergeant Kooperman

Sergent Kooperman is a character in The Super Mario Bros. Super Show!. He appears only in the episode "Plumber's Academy / Glasnuts" and lives in Brooklyn, New York. He is an instructor at Plumber's Academy.

He is a very strict man, and doesn't even care if one of the people in the academy die. He is voiced by the same person who voices King Koopa, making his voice sound like his. Though possibly done purposely, his last name sounds like Koopa, perhaps a reference to Bowser's common name on the show.
