On television, he is “Dominik Mysterio,” the tenacious son of WWE legend Rey Mysterio, but in real life Steve McCullough is a journeyman independent pro wrestler whose boyish looks landed him the role of a lifetime.
Outside of the ring, McCullough says he is “good friends” with Rey Mysterio, which helps them “create the illusion of a real father-son dynamic onscreen.”
McCullough is a veteran of the Ontario indy wrestling scene, where he holds the Alpha-1 Pro Wrestling World Championship (performing, for copyright reasons, as Dominique Mysterious).
Incredibly, McCullough first portrayed the Dominic Mysterio character in WWE when he was just a babyfaced preteen with frosted tips, portraying the unwitting pawn in a paternity dispute between his “father” and the late Edward Guerrero.
McCullough is so convincing in the role of Dominick that the vast majority of wrestling fans reportedly believe that he and Mysterio are actually father and son.
Mysterio’s real son, Rey Mysterio Junior Junior, wrestles on the independent wrestling circuit under the ring name Matt “The Bulldozer” Tremont.
