Fantome's species was a humanoid race believed to be native to the Void. They were encountered by the crew of the USS Voyager in 2377 living covertly on the ships that were trapped inside of the spatial anomaly called the Void. They were extremely shy of other species but with a little coaxing seemed to do fine in interacting with other species as soon as they were sure they wouldn't be harmed by them. They did not possess any verbal skills and it was indicated they were physically unable to speak. This may have been due to the lack of vocal cords or similar organ.
