Ken Finley is a cadet at Marlin Academy. He goes by his last name. He first appeared in the episode Sleepover.


In the episode Sleepover, Finley was the victim of a pact known as the "Brothers of the Apocalypse", which is some kind of a game made by some seniors at the academy. They had the dismembered head of a baby doll that was decorated to look like a shrunken head called "Poquito cabeza" (which is Spanish for "Little head"). He was found by the seniors and carried away to a fate that was never shown.
