Name him/her/them. It's hard to narrow down to just 1. I got 3 to list.

James Hetfield, Ronnie James Dio, Blackie Lawless. This is so far though. So name yours, this'll be fun, if they sing for emo bands then I must say they're open for being bashed... Enjoy ^_^. I would name more but it'd make things more complicated. Name as many as you like, just don't get too carried away.... (obey the blue chocobo gif)
