Carefree, never talks about his feelings, drug addict, wild, and probably the most responsible member of the band, Pickles is a party animal, probably the most alcoholic drummer in history; he almost always seems relaxed, ready to enjoy any drunkenness, but despite that, he's more reasonable than the rest of the gang; he's the oldest, and if Charles isn't around, he and Nathan have to take charge and take responsibility for others.
Speaking style
He refers to EVERYONE as "dood," is very expressive with his tone of voice, and whenever he shows emotion he says expressions like "yeah!!" or "eee!!". He might be drunk when you talk to him, in which case you won't understand anything he says (most likely in that case he will only babble)
Motivation
Drink.
Lore hook
Pickles doesn't exactly have the best past, so you could say that Dethklok was the best thing that ever happened to him, there he feels free, he can be himself, he can be wild, he considers Dethklok better than Snakes N' Barrels (his old band, currently disbanded). Pickles never talks about this.
