Fantome

Fantome was a member of a species that was native to The Void. He was encountered by USS Voyager in 2377 within The Void, aboard a derelict starship. Due to his large lung capacity, he was able to survive in an oxygen-less atmosphere for a certain period of time. He was also able to refract his lifesigns so that normal sensors couldn't detect him. Although incapable of speech, he learned to communicate with the Doctor using a system of musical notes. The Doctor took him under his wing, and named him after a character in the musical The Phantom of the Opera. He later assisted Voyager in its escape from The Void, along with three other members of his species. (VOY: "The Void")

Fantome was played by Jonathan Del Arco.
