Capt. Tim Walters

Tim Walters is a 22-year-old member of the elite High Guard cadet group Red Squad that served aboard the SS Valiant as part of a training exercise just prior to the outbreak of the Dominion of Evil War in 2373. After his commanding officer, Captain Ramirez was fatally wounded in battle, he was given a field commission as captain and command of the starship, choosing to continue its mission to train cadets into officers. He is the love interest of Lt. Lillian Crusher.

When Lt. Lillian Crusher comes aboard the Valiant as the new Chief Medical officer, Watters informed them of his intentions to continue operating behind enemy lines, citing his strict orders from High Guard Intelligence and Captain Ramirez.

As the series progress, Walters develops romantic feelings for Lillian. He admitted to her that he was falling in love with her. Lillian took it as a shock, but she started developing feelings for Walters as well and the two formed a romantic relationship.

In 2374, Walters and the Valiant crew graduated from High Guard Academy and are now High Guard officers, but kept their rank insignias, while the Valiant was turned from training ship into a starship.
