and Johnny Valiant formed a tag team in World Wrestling Association as storyline brothers. They began wrestling together as heels. They debuted as a team on 5 January 1974 when they defeated Dick the Bruiser and Bruno Sammartino to win the WWA World Tag Team Championship. The titles were held up after a match against Bruiser and Sammartino on 25 January. On 7 February, they defeated Bruiser and Sammartino in a rematch to win the titles a second time. Despite being heels, who usually are hated by the crowd, the Valiant Brothers were cheered by the audience during their second reign. Their tenure with WWA ended after they lost the tag titles to Wilbur Snyder and Pepper Gomez on 4 May.
Jimmy and Johnny signed with Vincent J. McMahon's World Wide Wrestling Federation in May 1974 and debuted there around soon after. Their biggest success as a tag team came when they defeated Tony Garea and Dean Ho to win the WWWF World Tag Team Championship on the 8 May 1974 edition of All Star Wrestling. The Valiants quickly became a dominant heel tag team as they went on to successfully defend their titles for over a year before losing them to Dominic DeNucci and Victor Rivera on 13 May 1975. This made the Valiant Brothers the longest reigning champions of their era with a reign of 370 days. The record was broken fourteen years later by Demolition, who reigned as tag team champions for 470 days. After losing the titles, the Valiants battled against the likes of Tony Garea, Dean Ho, Chief Jay Strongbow and Haystacks Calhoun.
In 1978, the Valiant Brothers returned to WWWF but Jimmy retired and was replaced by "brother" Jerry Valiant. Jerry and Johnny began wrestling in the tag team division while Jimmy became their manager. In March 1979, the promotion was renamed the World Wrestling Federation, dropping 'Wide' from the name. On the 24 March 1979 edition of Championship Wrestling, Jerry and Johnny defeated Larry Zbyzsko and Tony Garea to win the WWF Tag Team Championship. This second version of the Valiant Brothers was also successful, but Jerry could not achieve the popularity which Jimmy had achieved. In 13 July 1979, they retained the championship in a match against The Jaguar of Colombia and Tito Santana. Jerry and Johnny lost the titles to Ivan Putski and Tito Santana on 22 October. After unsuccessful attempts in winning back the titles from Putski and Santana, the Valiant Brothers broke up in 1980, putting an end to the team.
Aftermath
Jimmy and Johnny were inducted into the WWE Hall of Fameclass of 1996 by Owen Hart and "The British Bulldog" Davey Boy Smith. All three Valiant Brothers have reunited on the independent circuit during the 2000s. Jerry died on 10 March 2010 in Indianapolis after a battle with advanced Alzheimer's on set by post-concussion syndrome, while Johnny died on 4 April 2018 after being involved in a pickup truck crash in Ross Township, Pittsburgh, Pennsylvania, thereby ending any possibility of a reunion. Jimmy still wrestles for independent shows.
