There's nothing plot armory about the Beard. Plot armor is asspulling shit to keep someone in the game even when they're outmatched. Beard, on the contrary, has been consistently portrayed as the ultimate in mastery of pure martial arts. He doesn't really have any flashy techniques, he just turned his fingers into rebar through sheer training. Where his adversaries use limit breaks and special techniques, he just blocks, dodges by a hair, counterattacks. He's pure, distilled Karate. He's a simple fighter, just incredibly tough to surprise and overcome. None of his strengths come out of thin air to help him win, unlike Agito who's literally nothing but that.
