Tim Watters

Timothy "Tim" Watters was a Human/Betazoid hybrid Starfleet Captain and a former member of Red Squad in the late 24th century. He was the first youngest captain in history.
While aboard the USS Valiant during training maneuvers in 2373, Watters was chosen to assume a command role under the watchful eye of Captain Ramirez. Red Squad cadets under the supervision of a commissioned Starfleet officer manned all key starship officer positions, with the Valiant's primary training mission to circumnavigate Federation space. 
During a Cardassian attack, Captain Ramirez and all other commissioned officers were killed, leaving only the members of Red Squad to operate the Defiant-class vessel. Before his death, Captain Ramirez gave a battlefield commission of full Captain to Watters, inheriting orders to collect technical data on a new class of Dominion battleship.
Then, Lillian Crusher, a Starfleet Medical Academy graduate, joined the Valiant as the new chief medical officer. From the beginning, Watters was attracted to her right off the back, but their relationship was kept on a professional working relationship.
