Barry is an optional Pixl in the Wii game Super Paper Mario. His name is a real name, but used as a pun on his special ability: creating barriers. His ability to deflect and counter attacks is derived from the Superguard ability from Paper Mario: The Thousand-Year Door; additionally, the player that uses Barry will spin in a similar fashion.
Mario and Peach first meet Barry after Francis kidnaps Tippi. He reveals three tips on how to reach Fort Francis. Later, after Tippi is rescued and the player goes through the level again, Barry joins the party because he has nothing else to do. He can surround the main character with a strong barrier that can do damage to their enemies and deflect enemy projectile attacks back at the enemy (though it appears for only a few seconds). Barry does not realize that Mario was the great hero until he comes back to see him after defeating Francis - a fact that makes Barry ashamed, according to his Tattle. He is the only Pixl who does not recognize Mario as the hero right from the start.
Barry appears in volume 37 of the Super Mario-Kun manga, where, as in the game, he informs Mario that Francis has kidnapped Tippi.
