The Gracie family also experienced success in Vale Tudo fights and competitions. On April 25, 1980, "the torch" was officially passed to Rickson Gracie when he defeated Casemiro "Rei Zulu" Nascimento Martins by rear naked choke. Rei Zulu suffered a similar fate at the hands of Rickson again in January 1984 during their second encounter. Relson trained Rickson for both events in anticipation of fighting Zulu himself, but Relson later acquiesced to Helio's wishes for Rickson to make his debut as the Gracie family champion.
