Trip Tucker
Appearance
Commander Charles Tucker III, known as Trip (for "triple"), is a fictional character in the television series Star Trek: Enterprise. He is Chief Engineer on the the Enterprise NX-01. While a very knowledgeable engineer, he can be rash and "illogical" (to borrow a phrase from T'Pol).
Tucker had the dubious distinction of being the first pregnant male, in the episode "Unexpected".
Trip Tucker lost his sister, Elizabeth, in the Xindi attack on Earth.
