I would say Charles, Sadie, and Arthur in RDR2. Charles because he is able to keep his head, puts out a commanding aura when he needs, and does what needs to be done when it needs to be done. He doesn't get all hopped up over everything.
Arthur because he is a no bullshit kind of outlaw. When something isn't right, he makes it right by whatever means necessary. He'll kill you and think nothing of it if he deems it necessary. He kills in anger. He kills enemy gang members just for fun. And he can read the writing on the wall, when others can't even see it.
Sadie because she can get places that men can't. She can come across in the beginning as the demure little housewife, but the moment you let your guard down around her, you're going to end up as female as she is. You won't even know she cut your dick and balls off until after she shot you and the blood is flying. She won't tolerate belligerence towards those she cares about in the slightest way. When you're around people she loves, your life can literally be on the line, so you better at the very least be civil and cordial.
