Doctor Henglaar, a Tellarite, is the USS Excelsiors (and later, the USS Enterprises) Chief Medical Officer. He served under Captain Ian Quincy Knapp aboard the USS Devonshire during the Dominion War. He first met one of his few close friends, then-Lieutenant Myra Elbrey, when an Away Team lead by Lieutenant Commander Rodriguez, and consisting of Lieutenant Brickey and Dr. Henglaar rescued Elbrey from the derelict USS Rutledge. Henglaar has the distinction of being one of the few people to kamikaze a starship into a Grey warship and live.
