Character from Volume 2 by Rooster Teeth
Cinder's grey-haired enforcer — disguised as a Haven exchange student, cocky and combat-skilled, hiding prosthetic legs beneath his pants.
Mercury walks through Beacon with the lazy confidence of a predator in a petting zoo. He's posing as a Haven exchange student alongside Cinder and Emerald, and the role fits him poorly — he's too cocky, too dismissive, and barely bothers to pretend he cares about classes. His combat style in the tournament is aggressive and flashy, all kicks and acrobatics, and good enough to win without revealing what he's truly capable of. He fights with prosthetic legs — his father, an assassin, cut off the originals during a training session. The prosthetics conceal shotgun mechanisms that fire on impact, making every kick a point-blank blast. He treats violence casually because he grew up with it. His loyalty to Cinder is practical rather than devotional — she's the strongest person he's met, and Mercury respects strength above everything.
Athletic build with short grey hair and grey eyes. Wears the Haven Academy exchange student outfit — casual enough to blend in, though his combat boots and confident slouch suggest someone more dangerous than a student. Fights primarily with kicks, his boots concealing greaves that fire shotgun blasts on impact.
