Elroy Prescot, known in Japan as Sangre Guerrero, is the ninth ranking Pro League Duelist competing in the Genex Tournament. In the Japanese version, Elroy is a duelist who calls Belowski "Amigo". In the dub, he is an Elvis Presley impersonator who comes from the Memphis League. Elroy Duels Belowski but eventually surrenders due to Belowski's power to put people to sleep.
His Japanese name is Spanish for the words "warrior" and "blood". His English name is based on Elvis Presley.
The only known cards in Elroy's Deck are three copies of "Goblin Dancers".
