Square also incorporated several characters from the "Final Fantasy" series into the game, though the characters were slightly altered to fit the game's back-story. On the Destiny Islands, the player meets younger versions of Tidus (Shaun Fleming) and Wakka (Dee Bradley Baker) from "Final Fantasy X", and Selphie (Molly Keck) from "Final Fantasy VIII". In Traverse Town, the player encounters Squall Leonhart (also known as "Leon") (David Boreanaz) from "Final Fantasy VIII", as well as Aerith (Mandy Moore), Cid (Chris Edgerly), and Yuffie (Christy Carlson Romano) from "Final Fantasy VII". Rikku from "Final Fantasy X" was originally set to appear, but was replaced by Yuffie. Cloud (Steve Burton) and Sephiroth (Lance Bass), both from "Final Fantasy VII", make appearances in Olympus Coliseum, where the player can fight them in tournaments. The emphasis on characters from later "Final Fantasy" installments stems from Nomura's hesitation to use characters he did not design. The game also uses other "Final Fantasy" icons such as the Moogles who mediate item synthesis.
