I had to make a shitty metalocalypse reference because I literally made this asshole after binge watching it once.

Nils is a piece of shit narcissist metal guitarist with a coke problem who is just generally the worst. He probably doesn't give a shit about you because he cares about like two things other than himself and the twisted perception he has that he's a flawless human being. He's generally pretty apathetic, unless he's either preforming or his precious ego is being hurt.
