Backlash (2002) was a professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF) promotion, which took place on April 21, 2002 at Kemper Arena in Kansas City, Missouri. The event starred talent from the Raw and SmackDown! brands. It was the fourth event under the Backlash chronology and the final Backlash under the WWF name, as well as it being the final United States produced pay-per-view to use the WWF name. This was the first WWF pay-per-view event after the Brand Extension. The last time a WWF Pay Per View was held in Kemper Arena was WWF Over The Edge 1999. Nine professional wrestling matches were scheduled on the event's card

The main match from the SmackDown! brand featured Hollywood Hulk Hogan defeating Triple H to win the Undisputed WWF Championship and the featured match from the Raw brand was an encounter between The Undertaker and Steve Austin with Ric Flair as special guest referee, which The Undertaker won. The other main match from Raw was a Singles match for the WWF Intercontinental Championship between Rob Van Dam and Eddie Guerrero, which Guerrero won by pinfall to win the championship.

Paul Michael Levesque (born July 27, 1969) is an American professional wrestler, wrestling executive, and actor better known by his ring name Triple H, an abbreviation of the ring name, Hunter Hearst Helmsley. Currently, Levesque works in the front office of WWE as the Executive Vice President of Talent and Live Events, and as Triple H appears on television as the (storyline) Chief Operating Officer, and part-time wrestler.

Levesque began his wrestling career in the International Wrestling Federation as Terra Ryzing before joining World Championship Wrestling (WCW) in 1994. After briefly using the Ryzing name, he changed his character to Jean-Paul Lévesque, a French-Canadian aristocrat which would be similar to his character Hunter Hearst Helmsley, that he used in his early years with the World Wrestling Federation (WWF) from 1995 onward. He later abbreviated his name to Triple H and adopted an alternative image in the D-Generation X (DX) stable. After the dissolution of DX, Triple H was pushed as a main event wrestler, winning several singles championships. As part of a storyline Triple H married Stephanie McMahon, who later became his real-life spouse. In 2003, Triple H formed another stable known as Evolution, and reformed DX with Shawn Michaels in 2006 and 2009. He is heavily involved in the writing process of WWE programming, and holds complete creative control over his television character's storylines, win/loss record, and championship reigns.

Terry Gene Bollea (born August 11, 1953), better known by his ring name Hulk Hogan, is an American professional wrestler, actor, television personality, and musician signed to Total Nonstop Action Wrestling (TNA).

Hogan enjoyed mainstream popularity in the mid 1980s through the early 1990s as the all-American character Hulk Hogan in the World Wrestling Federation (WWF—now WWE), and was notable in the mid-to-late 1990s as Hollywood Hogan, the villainous nWo leader, in World Championship Wrestling (WCW). Following the closure of WCW, he made a brief return to WWE in the early 2000s before revising his heroic character by combining elements of his two most famous personas.

Hogan was later inducted into the WWE Hall of Fame in 2005. He is a 12-time world champion being a six-time WWF/WWE Champion, six-time WCW World Heavyweight Champion, as well as a former WWE World Tag Team Champion with Edge. He won the Royal Rumble in 1990 and 1991, making him the first to win two consecutive Royal Rumbles. He was also the first WWE wrestler to win the WWE Championship three times. In his first reign as WCW World Heavyweight Champion, Hogan held the title for 469 days from July 17, 1994 to October 29, 1995—the longest ever reign for this championship.

Steve Austin (born Steven James Anderson, later Steven James Williams; December 18, 1964), better known by his ring name "Stone Cold" Steve Austin, is an American film and television actor, producer, and retired professional wrestler. Austin wrestled for several well-known wrestling promotions such as World Championship Wrestling (WCW), Extreme Championship Wrestling (ECW) and most famously, the World Wrestling Federation (WWF). Described by WWE (formerly the WWF) chairman Vince McMahon as the most profitable wrestler in the company's history, he gained significant mainstream popularity in the WWF during the mid-to-late 1990s as "Stone Cold" Steve Austin, a disrespectful, beer-drinking antihero who routinely defied McMahon, his boss. This defiance was often shown by Austin flipping off McMahon and incapacitating him with the Stone Cold Stunner, his finishing move. McMahon inducted Austin into the WWE Hall of Fame in 2009.

Austin held twenty championships throughout his professional wrestling career, and is a six-time WWF Champion as well as the fifth Triple Crown Champion. He was also the winner of the 1996 King of the Ring tournament, as well as the 1997, 1998 and 2001 Royal Rumbles. He was forced to retire from in ring competition in early 2003 due to a series of knee and neck injuries sustained throughout his career. Throughout the rest of 2003 and 2004, he was featured as the Co-General Manager and "Sheriff" of Raw. Since 2005, he has continued to make occasional appearances. In 2011, Steve Austin returned to WWE to host the reality series Tough Enough.

Mark William Calaway (born March 24, 1965) is an American professional wrestler better known by his ring name The Undertaker. He is signed to WWE and is the company's most tenured competitor. Calaway began his wrestling career with World Class Championship Wrestling (WCCW) in 1984. He joined World Championship Wrestling (WCW) as "Mean" Mark Callous in 1989. When WCW did not renew Calaway's contract in 1990, he signed with the World Wrestling Federation in October and, after shortening his name from Kane the Undertaker to simply The Undertaker, has remained with the company since.

The Undertaker has two contrasting personas. The first is the role of The Deadman, an undead, occult-like figure, which has consisted of many different styles. He debuted his original Deadman persona during his own on-camera debut at Survivor Series (1990). At this event, the Undertaker was clad as a Western mortician. Next, in October of 1998, the Undertaker appeared as the leader of the Ministry of Darkness (with similar apparel). Since WrestleMania XX, the Undertaker has appeared as a hybrid version of the Deadman character, using elements of the previous Deadman incarnations.
