Adam Martoni was a Cadet at Starfleet Academy who liked to play practical jokes on other cadets during the mid-2360s.
During Wesley Crusher's first week at the Academy, Martoni reprogrammed Crusher's sonic shower to cover him with mud. Crusher managed to "get back at" Martoni when he reprogrammed an antimatter regulator to spray him with chili sauce. (TNG: "The Game")
