Meanwhile, Jean Gagné also wrestled in Puerto Rico's World Wrestling Council under his own name, and in the first half of 1978, he and partner Huracán Castillo traded the WWC World Tag Team Championship with the tag team of Invader I and José Rivera, holding the title once. He also held the WWC Caribbean Heavyweight Championship and the WWC North American Tag Team Championship, the latter he held four times; one of the times was with Michel Martel as part of a tag team called The Mercenaries.[4][5] While in Puerto Rico, he wrestled Ric Flair in a match to a 60-minute time limit draw.[4] Gagné also wrestled under the name Mad Dog Martin in Australasia and the South Pacific during the mid to-late 1970s. 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.[6]
