The Boulder

Initially, The Boulder felt conflicted about fighting a young blind girl, but he quickly overcame these feelings, ready to unleash a ‘rockalanche.’ He was a professional earthbending wrestler who participated in the Earth Rumble tournaments. He later went on to fight for the Earth Kingdom and assist in the invasion of the Fire Nation along with The Big Bad Hippo.
