It's much more than fighting style. His movement, body, face, his gaze, etc. He's clearly hardcore and going no bullshit full speed, and ther eis an ascetism probably goes throguh intense training. its a badass villain.

Much mroe than just looks but again you re not that intelligent so you wouldnt get it. or maybe you re just young so you shoudl refrain from having opinions.
