These characters form the "Hollow Bastion Restoration Committee" in Kingdom Hearts II, with the goal of rebuilding their destroyed world following Maleficent's defeat, using the home of Merlin as a base. In both games, Leon and Yuffie are featured as opponents in the Olympus Coliseum. The Restoration Committee return in Kingdom Hearts III Re Mind, helping Riku search for clues to the missing Sora's disappearance. Youthful versions of Final Fantasy X characters Tidus and Wakka, as well as Final Fantasy VIII character Selphie Tilmitt, make recurring appearances as residents of the Destiny Islands.
