Character
He hunts through stealth.
His ideal target's first instinct would be to flee, since freezing makes them boring and he doesn't want to heal wounds caused by fighting.
If they run, it gives him a good chase without harming him.
He's as normal around his targets as you can get here, he thinks of them as how a cat would think of its toys.
He got that scar from an unfortunate near-fumble early on in his career.
He tried to toy with his target a little too much, losing his chance to finish him off without having anyone else be alerted.
He only barely got out with his life there, and since then he's been hesitant to toy with his targets in the same way.
