Sure, Sauron has the One Ring. But, Kirk has the resourcefulness of a planet killer killer.
I give the edge to Kirk, since he’s got both a dark side and a good side.
Here is some diologue for your pleasure:
Kirk: Sauron, you bloodsucker. You’re gonna have to do your own dirty work now, do you hear me? Do you?
Sauron: Kirk. You’re still alive, old friend.
Kirk: Still, “old friend.” You’ve managed to kill everyone else but like a poor marksman, you keep missing the target.
Sauron: Perhaps I no longer need to try, Admiral.
[beams the One Ring away]
Kirk: Sauron… Sauron, you’ve got the Ring, but you don’t have me. You were going to kill me, Sauron. You’re gonna have to come down here. You’re gonna have to come down here.
Sauron: I’ve done far worse than kill you, Admiral. I’ve hurt you. And I wish to go on hurting you. I shall leave you as you left me, as you left her: fingerless for all eternity in the center of a dead planet, buried alive. Buried alive.
Archer: Grrrr…snarl…I’m in a crappy mood that’s lasted since “The Expanse” and I’ve alienated every one of you. I wish to go on…alienating you. All I do anymore is yell, complain, furrow, push, grab, shove and threaten. Even my dog doesn’t want me around anymore. I’m psychotic and I don’t care who knows it.
Crew plus Porthos: All right, that’s enough. We’re airlocking you and blowing your grouchy ass out into a perpetuatizing reflective anomaly so you’ll have to spend eternity staring at your own sour face.
