At first glance, Katsuo and Mercer seem to have quite a bit in common, at least superficially. They're both pretty rugged-looking, tough, always itching for a good fight... and quite keen on putting on a good show, like breaking out in a spar in the middle of a crowded street. Judging by the crowd of spectators and the sheer number of phones held aloft, I'd say they definitely know how to captivate an audience.
