During his World Wrestling Federation heyday in the 1980s as the manager of Canadian wrestler Dino Bravo, he was known for his trademark sign that read "USA is not OK".

[4] In June 1977, Gagné, under the name Frenchy Martin, won the IW North American Heavyweight Championship in Trans-Canada Wrestling.

In their second bout, they defeated Great Kusatsu and Mighty Inoue in a two-out-of-three falls match to win the IWA World Tag Team Championship.

On September 28, 1978, he won the NWA British Empire/Commonwealth Championship from Steve Rickard and defended the title for several months before dropping it to Leo Burke the following year.

[7] In 1980, under the name Masked Cyclops, Gagné won the NWA Pacific International Championship from Tor Kamata, but he lost it later that year to Siva Afi.

In August 1987, he began to be the host of a WWF's skit "Le Studio" (presented only in Canada, during Superstars of Wrestling); during the segment, he would interview his guests and translate their answers in French, using the opportunity to mock the faces and praise the heels.

Since he spoke fluent Spanish from his years in Puerto Rico, he hosted a similar segment for WWF's Spanish-language TV called "Frenchy's Easel."

Throughout 1987, he would make regular appearances as color commentator on the French-language WWF programming alongside Edouard Carpentier and Guy Hauray.

At the International Wrestling 2000 card at the Centre Pierre Charbonneau, Gagné as Frenchy Martin managed Richard Charland in the semi-main event against King Kong Bundy.
