But... it's up to individual people who's a badass. Kled, to me, is a badass because he keeps fighting no matter what. Even when the odds are against him, he never considers surrender. Total badass, with a humorous theme. Next up, I find Vi to be a badass. She has giant gauntlets, and she has a far more direct approach to the policing business. Her way of fighting, along with her past as a criminal being used to interrogate people, makes her a badass to me. Talon is a badass, as he ruthlessly hunts his target, scaling walls and slipping past defenses to get to his prey, no matter where they are.
Ivern is, get this, a badass. "But midnight," you say, "Ivern is a wimpy champ who doesn't even fight!" But that's what makes him a badass. In a world full of violent people who fight pointless wars and refuse to listen to reason, Ivern sees the best in things. He travels around making people's lives better, being kind and supportive and understanding. And that makes him the biggest badass of them all. Besides maybe Braum.
Jhin just kinda sits around and gets uncomfortably happy when killing people. Not a badass, in my eyes.
