Asian Mercenery is the only being in DCEU Universe that managed to actually hurt Bruce Wayne A.K.A Batman. He is strong enough to survive being stabbed with a knife.
It's worth noting that the very same dagger was able to hurt Batman and pierce his suit, something Doomsday and Superman never accomplished.
On top of that he possess freakish blunt force durability. He is tough enough to take Bruce's punches and recover in relatively short amount of time.
As if taking Wayne's punches wasn't enough, Asian Mercenary could withstand full force of his kick.
His unnatural endurance was presented during his very first appearence. Asian tanks an explosion that was strong enough to blow a rifle into pieces.
Probably the most underrated aspect of the character. People firmly belive that this guy is on par with the likes of Bruce Lee or Ip-Man. It is, in my humble opinion, a serious lowballing that is born from ignorance.
Asian Mercenary was the only person in entire history of Batman Movies, to actually use his cape against him. Such act was very rarely seen even in comic. You know who is the only other person that utilized Dark Knight's cape against him with such sucess? Ra's al Ghul
Centuries old. Supreme swordsman of DC Universe. Personally trained first fencers on the planet and the most dangerous men on Earth. Capable of manipulating events on entire planet.
Asian Mercenary replicated the very same technique Ra's used. Being capable of using such risky and sublim move should put him among the most skilled comic martial artists. Yes, ladies and gentlemen, the only cinematic character (barring CW Oliver Queen) that can match their comic counterpart.
