If i had to guess, in 1v1 combat
0) Jaquen / Arya
- They're assassins. They are able to kill their enemies without them even knowing they were in danger in the first place. Thus, with prep time they could kill just about anyone on any of these lists, free.
- Arya's planning to
kill Cersei. There's little reason to believe she couldn't manage to do it. She ended an entire bloodline ffs
1) Oberyn
-
He fights with a spear. Immediate advantage over all these silly swordsmen
- A poison-tipped one at that, but it's clear that he didn't actually need it to finish Gregor off.
- He beat the mountain
2) Barriston / Jamie
- Because literally everyone in the show say they were both the realest shit when one wasn't dead and the other was whole.
3) Arya (forreal) / Brienne / The Hound
-Arya,
purely for the element of surprise. I highly doubt anyone would think much of short little Arya and her shitty little needle. She plays coy, fight starts, she kills them in one stroke.
1v1 against an opponent who actually took her seriously, I doubt she'd fare as well, as seen by Brienne's ability to lay her flat on her ass with one kick.
-The Hound wasn't at full strength fighting Brienne, he was suffering from a festering wound by his neck. So I really don't know how to rate either of these two.
- If i had to actually split them for duels, i'd go
Brienne / The Hound / Arya.
4) The Mountain
- Because nobody else in the show probably could have dealt with him, to be honest.
5) Jon Snow
- Because nobody has actually managed to kill him in combat
Not a lot of Khal Drogo in here
Probably because technically, that guy killed him.
Shit like that is how smarter characters would end up undoing him, even if Drogo is one of the best fighters on these lists skill wise.
