Sergeant Cole is a one-time character from The Mask: The Animated Series, during the season 2 episode, The Green Marine. He was The Mask's squadron's drill sergeant who tries to expose his chaotic antics after causing trouble with him.
- Sergeant Cole's role in The Green Marine bares similarities to Greenfield from the other Season 2 episode, Mr. Mask Goes to Washington. They both have high positions involve serving for the United States, they were The Mask's supervisors when he was working for them, victims of The Mask's antics when provoking him and faced punishment from their higher commanders when accidentally caused trouble for them when attempting to expose The Mask of his troubles. Except, at the end of Mr. Mask Goes to Washington, Greenfield succeeded in exposing The Mask of his troubles by showing the President a video of him taking a bribe, causing The Mask to lose his chance of becoming vice president and forced to resign. At the end of The Green Marine, Sergeant Cole failed in his attempt to expose The Mask's chaotic actions during his court-martial to the judge when the folder he was presenting has a large bite mark on it, (due to The Mask eating it when no one was looking), causing The Mask to get away with his actions and become lieutenant for the US Marines, upsetting Sergeant Cole for a short moment, but he happily joined in a celebratory conga line with The Mask and everyone in the courtroom.
