The tenth game of the Final Fantasy series, Square's 2001 best-selling role-playing video game Final Fantasy X features several fictional characters designed by Tetsuya Nomura who wanted the main characters' designs and names to be connected with their personalities and roles in the plot.

The leader of the Guado tribe, Seymour Guado, briefly joins the party for a fight but is then revealed as an antagonist in his quest to replace Tidus' father, Jecht, to become the new Sin.
