Marv from Sin City was a big inspiration for me in creating Dogberry. Marv has a lot of problems, but in his own way he's got a strong moral compass and knows how to enjoy the simpler things in life. Obviously Dogberry can cope a little better with his problems, but the idea of a scratched up hulk with self-control issues was more or less the cloth Dogberry was cut from.
