Kyle Kupiszewski, known as "Kup" to his buddies, is a young navy chef residing in Portsmouth, New Hampshire.

A cook aboard nuclear powered submarines, Kup is used to serving 150 helpings of hash browns and bacon in one sitting, so he isn't fazed by pressure. However, he arrived at the Academy with a limited range of dishes and techniques and was therefore nervous about learning how to cook under the renowned Chef Novelli. He may look like a muscular sailor with attitude and tattoos, but Kup may have been the student who most desperately wanted to impress Novelli.

Toughened by years of Navy experience (he once spent 91 days underwater) nothing much fazes Kup. During the series, he shows he has a short fuse and doesn't take kindly to childish behavior. He forms a close friendship with Kyle, the other alpha male type in the group, but clashes with some of his female classmates. Kup is now back on active duty with the Navy.
