Catching Up With The Traveler, Eric Menyuk. If the chips of fate had fallen differently, Eric Menyuk might have played Data for seven seasons on Star Trek: The Next Generation and in the four TNG big-screen adventures.

The Traveler, whose real name was unpronounceable by Humans, was a mysterious humanoid native to Tau Alpha C and from Tau Ceti, who had the ability to alter space, time and warp fields with the power of his mind. He could phase out of time and dimension and move between planets and starships.
