Flag Guy is the unofficial name for a Shy Guy who serves General Guy in Paper Mario.

After Mario defeated the Shy Squad, the Flag Guy appeared, waving a flag for General Guy to come in in his tank. General Guy accidentally hit the Flag Guy, who ran away.

He also appears in the credits parade, waving a signal flag, except this time to signal the stage (featuring General Guy, two Shy Guys, and four Groove Guys dancing) that was moving along the parade road.
