Boone, along with Billy Jack Haynes, worked as a jobber tag team for the World Wrestling Federation from late 1986 to early 1988. Boone began wrestling full-time for the WWF on July 2, 1987, used primarily as an upper-level opening match wrestler. Despite his role on television as a jobber, Boone won many matches on the house show circuit including defeats of Barry Horowitz, The Gladiator, José Estrada Sr., and ultimately compiled an overall singles record that included nineteen wins that year. Meanwhile, on television Boone lost almost all of his encounters, but challenged The Honky Tonk Man for the Intercontinental Championship on the December 8, 1987 and May 10, 1988 episodes of Superstars. Boone was involved in one major angle on October 31, 1987, when he tagged with Scott Casey in a losing effort against Demolition. Following the match, Demolition continued to attack Boone, leading first Billy Jack Haynes and then Ken Patera (Haynes' ally in a recent feud with Bobby Heenan) to make the save but also be beaten down. Boone was stretchered out as a part of angle that led to Demolition feuding with the team of Haynes and Ken Patera plus various other allies. The following year Boone won an additional 24 matches, and finished his run with a victory over Steve Lombardi on September 12, 1988 in South Bend, Indiana.
Brady Boone returned to the WWF on May 4, 1990 on a house show in a loss to Paul Diamond. He wrestled in numerous house show and television matches between May and August. At a house show on September 13, 1990, Boone debuted as Battle Kat, a character who donned a cat mask and utilized his gymnastics background to emphasize his "cat-like" agility. He pinned The Brooklyn Brawler. Six days later, Battle Kat won his televised debut match over Bob Bradley, on the September 19 episode of Wrestling Challenge. Battle Kat remained undefeated on house shows and defeated Paul Diamond on the October 30 episode of Wrestling Challenge before he was released from the WWF. Bob Bradley then replaced Brady Boone in the Battle Kat character.
Boone signed with World Championship Wrestling in 1993, and debuted (as Brady Boone) on the December 7 episode of Saturday Night, losing a tag team match (with partner Scott Studd) to Pretty Wonderful (Paul Orndorff and Paul Roma). On the January 10, 1994 episode of Saturday Night, Boone lost to Steve Austin. After not appearing on television for several months, Boone wrestled his final match on the July 23 episode of Saturday Night, defeating Rip Rogers. After retiring as a wrestler, Boone remained with the company as a referee.
On December 15, 1998, Boone passed away.
