From 1969 through 1973, he enjoyed a protracted stint in the WWWF as a mid-card babyface, losing to top-tier heels like Killer Kowalski and Toru Tanaka, but repeatedly holding the notorious Baron Mikel Scicluna to a draw, and regularly defeating jobbers like Angelo Savoldi and Johnny Rodz.
After he retired from active competition, Valiant went on to a successful career as a manager; most notably leading the "Dream Team" Greg Valentine and Brutus Beefcake to the WWF Tag Team championship in 1985.
He left but soon moved on back to the WWF to his Dream Team who famously defeated Barry Windham and Mike Rotunda for the titles by rubbing Johnny V's lit cigar in their eyes. After his Dream Team lost the Tag Titles to the British Bulldogs at WrestleMania 2, Johnny V added Canadian strongman Dino Bravo to his stable. At WrestleMania III, Valiant, Valentine and Bravo abandoned Beefcake in the ring after a battle with The Rougeau Brothers and the New Dream Team of Valentine and Bravo was born. Not as successful as the first incarnation, this Dream Team had a lengthy feud with the scorned Beefcake, now known as Brutus "The Barber" Beefcake, in which Beefcake famously cut and ruined Johnny V's hair. Also in this stint in the WWF, Johnny V was known to do commentary on matches from time to time and introduced the team of Demolition before they were paired off with Mr. Fuji.
In 1996, he was honored by being put in the WWE Hall of Fame.
