Sione Havea Vailahi is a Tongan professional wrestler, better known by his ring name, The Barbarian. He is best known for his various stints with The National Wrestling Alliance (NWA), World Championship Wrestling (WCW) and WWE and for being a part of tag teams The Powers of Pain with The Warlord and The Faces of Fear with Meng. His first national exposure was in the NWA territory Jim Crockett Promotions (JCP), where The Powers of Pain held the NWA World Six-Man Tag Team Championship until they departed the company in 1988 and joined WWE, where they competed in the tag team division until the team was quietly split in 1990. The Barbarian then competed as a singles wrestler until departing in 1992 and returning to WCW, where he became one half of the final WCW United States Tag Team Champions with Dick Slater. During this time, The Barbarian challenged Ron Simmons for the WCW World Heavyweight Championship at Halloween Havoc '92. He left WCW in 1993 and returned to the WWF in 1994 as Headshrinker Sione to form The New Headshrinkers with Fatu. He left the company in 1995 and made a second return to WCW, where he briefly reunited with The Warlord as The Super Assassins. The Barbarian would then join Meng to form The Faces of Fear and become a part of factions Dungeon of Doom and The First Family.
