Muto George competes as a platinum-ranked rival on the Bottleman battle circuit. He performs in a rock band with his twin brother, Yukiji Muto, weaving music directly into his competitive tactics.

George sports curly black hair featuring a bright red fringe and blue eyes. His look includes black nail polish and a black choker detailed with grey studs and a gold diagonal cross. He typically wears a greyish-black vest with ripped sleeves displaying a pale blue vortex logo, paired with black ripped jeans, armbands, and a black belt sporting a silver buckle. His signature look is completed by a dark blue, pale blue, black, and yellow-accented guitar carried on a black strap.

In Bottleman battles, George commands the power-type Bottleman Fujin Black. His rock background shapes his battling style; his guitar playing manipulates the arena environment, transforming surfaces into literal metal to forge tactical advantages for vertical shots and other strategic moves. This exemplifies the connection between his music and combat techniques.

George engages in high-stakes battles, including team confrontations. During the season finale, he partners with his twin brother to challenge the duo of Cota Coga and Hokari Ryo, underscoring his role as a significant rival.

His character name originates from Georgia, a Japanese coffee brand, continuing the series' beverage-inspired naming theme.
