IN: Lieutenant Reginald Endicott "Reg" Barclay III, portrayed by Dwight Schultz, is a fictional character from both Star Trek: The Next Generation and Star Trek: Voyager, in the latter of which he plays a vital role in re-establishing regular contact between the starship and Starfleet. The character also appears in the 1996 feature film Star Trek: First Contact.

Barclay appears as a guest character in Voyager. His first appearance is in the third episode of the second season, "Projections", although this is as a holographic character. In this episode, it is claimed that Barclay worked with Dr. Lewis Zimmerman to develop the EMH doctor program, although since Barclay's appearance is actually caused by a holographic breakdown this may not actually be the case.  Working on Starfleet's "Pathfinder" project, Barclay becomes obsessed with the crew of the lost USS Voyager, which has been stranded in the Delta Quadrant for over five years. He once again creates simulacra on a holodeck, this time of the Voyager crew, but based on facts available to him about their true personalities (for the most part; because he named his cat Neelix, he makes the holodeck Neelix purr). With the help of these holograms and Deanna Troi--with whom he has developed a close friendship--he devises a method to use a micro-wormhole to establish two-way communication with Voyager. This plan is initially shot down, but Barclay defies direct orders and breaks into the laboratories, ultimately making successful contact with the real Voyager. During this incident, Barclay also works through his relapse into holo-addiction; as he reveals to Deanna, he'd lost his "family" after leaving the Enterprise and did not know how to cope except with fake people.  Barclay's work on the Pathfinder project earns him a promotion to full lieutenant (previously he had been a lieutenant junior grade). During this period ("Inside Man"), a hologram of him is sent to Voyager to help them find a way home, but the hologram was altered by Ferengi trying to acquire Seven of Nine's Borg nanoprobes by convincing the crew to attempt a method of return that would have destroyed all organic matter on the ship. Barclay and Troi manage to work out what is happening, and Barclay is then able to dupe the Ferengi into abandoning their plan by posing as the hologram and claiming that Voyager was equipped to survive the trip and was more heavily armed than they actually were.  An alternate future in the Voyager series finale "Endgame" shows an older Barclay teaching at Starfleet Academy, with the rank of Commander. By this point, Barclay has long since conquered his negative personal habits and is much more confident and secure with himself. The proper timeline's version of him is present when a transwarp aperture opens near Earth. Correctly deducing that it has been opened by Voyager, he witnesses the battle that follows with the Borg sphere and Voyager's return to the Alpha Quadrant.

Does he appear in any other episodes?

IN: Nightwish is a symphonic metal band from Kitee, Finland. The band was formed in 1996 by lead songwriter and keyboardist Tuomas Holopainen, guitarist Emppu Vuorinen, and former lead singer Tarja Turunen. The band soon picked up drummer Jukka Nevalainen, and then bassist Sami Vanska after the release of their debut album, Angels Fall First (1997). In 2001, Vanska was replaced by Marco Hietala, who also took over the male vocalist role previously filled by Holopainen or guest singers.

Earlier Nightwish performs symphonic metal with soaring female operatic vocals. Their music has been described as "bombastic heavy, symphonic and cinematic, with keyboards and strings creating a gothic atmosphere". They have also been known to play power metal and gothic metal.  The band's music is also known to be complex and layered. Their approach is epic, theatrical and operatic. Critic Chad Bowar notes that the music is "always very melodic with memorable choruses and a lot of hooks."  The usage of a female vocalist has become a sort of trademark, though less so since the outbreak of new female fronted metal bands in the mid-2000s with the popularization of bands such as Evanescence and Leaves' Eyes as well as several gothic metal bands mixing female and male vocals, such as Lacuna Coil, Tristania, Epica and the early Within Temptation.  Bassist and vocalist Marco Hietala describes the style of the band's music as "melodic symphonic metal;" though this is not a view shared by all members of the group, including band composer Tuomas Holopainen, who describes the band as simply symphonic metal. Some critics find that the band had a gothic sound since their debut. The music of Nightwish had been "distinguished by the operatic voice" of soprano Tarja Turunen, a "charismatic frontwoman with a powerful voice". Critics observed that her vocals became less operatic with the release of Once. Following the departure of Tarja Turunen from the group, Nightwish left behind the "signature operatic vocals" of their earlier albums.  While the music of Nightwish is centered around a female lead singer, the band has also featured some male vocals on their albums ever since their debut release Angels Fall First. This debut album also included "elements of folk music and ambience" that were discarded on their subsequent album Oceanborn. However, the song "Creek Mary's Blood" from the album "Once" featured some use of folk-oriented Native American melodies, and their 2007 release Dark Passion Play featured folk music elements on the songs "The Islander" and "Last of the Wilds".
