Richter returned stateside signing with the World Wrestling Federation (WWF) in late 1983. In April 1984, Richter teamed with Peggy Lee for a series of matches with old rivals Velvet McIntyre and Princess Victoria. WWF owner Vince McMahon brought in Cyndi Lauper for a feud with Lou Albano (who had appeared as Lauper's dad in her "Girls Just Want to Have Fun" music video). Albano seconded WWF Women's Champion Fabulous Moolah, while Lauper was in the corner of Wendi Richter. Richter defeated Moolah at MTV's "The Brawl to End It All" for the Women's Championship on July 23, 1984, with Richter lifting her own shoulder off the canvas during a double-pinfall situation while Moolah's shoulders remained down. With the win, she ended what was billed as the longest championship reign in professional wrestling history (Moolah's 28-year reign as recognized by the WWF; in reality she had lost the title several times between 1956 and 1978, and Richter's win had in reality only ended a nearly seven-year reign by Moolah as champion). The broadcast of the women's match earned MTV its largest ratings in history up to that point. This match was also the beginning of the "Rock 'n' Wrestling Connection", an era that combined both music and professional wrestling. Richter faced Moolah's protégé, Leilani Kai, who defeated Richter for the title, in early 1985 at "The War to Settle the Score". She regained the title at the first WrestleMania one month later. While wrestling for the WWF, Richter referred to herself as "150 pounds of twisted steel and sex appeal". Richter was also animated for a CBS Saturday morning cartoon, "Hulk Hogan's Rock 'n' Wrestling". In addition, she appeared in Lauper's music video for "She Bop".
