Decado the ice killer:
Relentless, warlike, maybe even spiteful as a bonus. Not particularly liable to forget about the whole thing with a bit of a chuckle, in a moment of warmth.
Insane reflexes. Preoccupied with war and combat. -If you somehow caught him off guard he might still sidestep where he predicts/sees out of the corner of his eye your crossbow's aim, and then there's no escaping him to roll the dice again some other day: This guy is fast enough to not just beat a mind reader, but beat him hands down no contest. (Imo he's the least human character in the series, -more like a god of war.)
And catching him off guard is almost impossible anyway, because for him outmanouvering people is beyond an obsession -It's not what he does, it's what he IS. On guard and hyped as hell is his default state of mind.
So with every other hunter you might have a chance if you were able to be extremely patient, and wait to ambush them, put the word out to warn you, etc, but Decado could probably walk in the front door of your own castle and still end up killing you.
