My current king is about to retire so I've planned out my heir's design but I have no clue what to name him

Here's my heir in all his glory

Wardrobe link in case the image doesn't load

I've gone for sort of dark, punk kinda look so I'd like a name that matches that vibe! It could be a human name, word name, a reference to mythology; anything works!

(I'll give out rewards if I like your suggestion )
