Answer the question at the end by quoting:

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.

What are some of the episodes that he was featured in?

His first appearance is in the third episode of the second season, "Projections", although this is as a holographic character. In

IN: Hed PE (also known as (hed) Planet Earth and stylized as (h@d) p.e.) is an American rock/hip hop band from Huntington Beach, California. Formed in 1994, the band is known for its eclectic genre-crossing style, predominately in the fusion of gangsta rap and punk it has termed "G-punk", but also for its reggae-fused music. The band's cross-genre mix of styles has been cited by journalists as having a considerable impact on rap rock and nu metal, though no firsthand accounts of the band influencing bands in either genre exists and the band itself has denied being a part of these styles, identifying more as a punk rock band utilizing rap vocals in conjunction with other vocal styles (melodic reggae singing, screaming and death growls) rather than being a rap rock band in of itself. One reviewer described the "nu metal" categorization as being a mistaken association.

Hed PE performs a style of music which they have referred to as "G-punk", a phrase inspired by the term "G-funk". Hed PE has also described its music as "schizophrenic". Hed PE's music is a fusion of styles ranging from hip hop, reggae, and ska to hard rock, punk, and heavy metal. Other elements that have been incorporated into this style include blues, funk, jazz and industrial. Jared Gomes' vocal style ranges from melodic singing to rapping, screaming, and death growls. The band's lyrics draw from a number of subjects, including social justice, the existence of extraterrestrial life, criticism of organized religion, the 9/11 Truth movement, cannabis use and sexual intercourse.  The band has disassociated itself from nu metal and rap rock, with former guitarist Jaxon stating that "I wouldn't call our band nu metal" and Gomes noting that his vocal style is wider ranging than simply rapping. Regarding the band's association with nu metal, Kik Axe described the band as being "mistakenly lumped" into the genre, while Beatdust described the band's sound as helping shape nu metal, listing Linkin Park and Limp Bizkit as bands it believes were influenced by Hed PE. Hed PE itself claims that Linkin Park was influenced by Hed PE's music and that Fred Durst listened to Hed PE frequently while recording Limp Bizkit's debut album; these claims, however, have not been backed up by either Durst or Linkin Park.  Gomes, in addition to the 9/11 Truth movement, has expressed support for social liberal politicians such as Nancy Pelosi and president Barack Obama. Previously however, Gomes' 2004 lyrics for Only in Amerika expressed support for nationalism, and called for retaliation against Al Qaeda for the 9/11 terrorist attacks.

Were they at one time called nu metal?

OUT:
