Guh, if I could marry a pair of vocal chords . . .
Brief little description: David is a singer with a very rough past. Despite experiencing death first-hand, he has matured through his music and is very straight-edge; he doesn't even drink much (part of this is because he has Acid Reflux disease) Rough and tough, he may not be very tall but his hulk makes him pretty damn intimidating. His voice can produce shock waves that hit his opponents like sledgehammers. And those piercings on his lip aren't just decoration; they contain a fearsome demon the band has dubbed as "The Guy." Rip them out and the demon will be unleashed.
The Guy first appeared to David after his girlfriend suicided when he was only sixteen. Grief-stricken and heart-broken, he slipped into despair and, taken advantage of David's weakened state, The Guy possessed him to carry out his plans of inflicting justice, while at the same time spreading anarchy and chaos. David soon learned to restrain him through his lip piercings. Although he is not outright evil, The Guy is still very dangerous and David will only let him out in dire situations. The Guy will gladly take down Hitler or any other villainous person--but he'll be sure to destroy a couple buildings and kill a few dozen people as he does so.
Gawd, I must be insane . . .
