Willard Decker
Like father, like son.
Willard Decker was the son of famed Starfleet Commodore Matt Decker. After Will was relieved of command by Admiral James T. Kirk –somebody really should make a note of Kirk's never-ending quest to relieve all captains named "Decker"— the disgruntled Executive Officer committed suicide by merging with a blow-up doll. (Star Trek: Encounter at Farpoint)
Decker was regenerated as Willardiam RiDecker, remained a second stringer, and eventually merged with a blow-up doll. (TNG: "Star Trek: The Next Generation: The Motion Picture", Star Trek: More Khan, Less Character.)
