Aragorn from Lord of the Rings.
I'm the quiet guy, sitting alone in the corner of the bar, trying not to draw too much unwanted attention.

Sephiroth from Final Fantasy VII.
You know, the pissed off, crazy guy, obsessed with the magic that should not be, that you keep killing because (funny thing) he doesn't seem to ever stay dead. (hhmm, gee, I wonder why...)

Alice Quinn from The Magicians.
I spend most of my time nose-down in books or articles, keeping to myself mostly because knowledge and information is escapism to me. I'm aware I'm not liked because of this and like Rhett Butler in Gone With The Wind says to Scarlett O'Hara: "Frankly my dear, I don't give a damn."

And if we're including literary (besides the two that I already have) than Asenath, from The Thing On The Doorstep, by H.P. Lovecraft.
Because I can do that thing with your mind that you like. :-P

(I'm entirely mental. If this deduces nothing else, it deduces that.)

Can't think of any at all. If I asked people I know which characters I'm most like, I don't know what they would say.

still wondering about interesting one

I am a Supermario. When i would have to decide between watching or streaming video games, I would probably go for the second one. Really enjoy watching these guys https://profilerr.net/pl/cs-go/pro-players/ playing and how calm they are doing that. I am a very emotional person, so that wouldn't be possible with me.
