Sir Royal the 3rd competes for the American team "3S" in the "Big Battle August" world fighting championship. He engages in a one-on-one duel against J from Otokojuku within a cave environment. The ferocity of their clash triggers extensive structural damage, culminating in the cave's collapse. After this destruction, J is temporarily presumed deceased but later emerges alive alongside Togashi and Edajima. This confrontation occurs during the tournament arc featured in the anime movie *Charge!! Men's Private School*, where Otokojuku's first-year students confront international opponents. Sir Royal the 3rd exclusively functions as an antagonist within this tournament, with no subsequent appearances in spin-offs, OVAs, or manga arcs.
