10 Star Trek Characters Who Appeared On Multiple Series
5. William Riker
WIlliam Riker is as loyal a First Officer as a starship captain could ever hope to find. Riker served on the Enterprise under Jean-Luc Picard, turning down opportunities to have is own command to stay on most prominent ship in the fleet alongside its most respected captain.
Over the years, Riker has made several appearances on other series. In one of Q's Voyager episodes, the powerful imp dragged Riker all the way to the Delta Quadrant and on board Janeway's stranded ship. He was one of the few characters from other series to make an appearance on Enterprise, popping up in the finale. Riker has also played a more recent role in the newest Star Trek series, Picard.
The most confusing Riker appearance was on Deep Space Nine, though it wasn't WIlliam Riker. An episode of TNG showed that a transporter accident on an away mission several years earlier had accidentally created an exact duplicate of Riker who remained stranded on the planet. Going by Thomas Riker, he eventually joined the Maquis, a terrorist organization, and impersonated William Riker in order to hijack the USS Defiant.
Thomas Riker was last seen being taken into custody by the Cardassians.
