Big Steve (Steve O'Mara) is a big slab of meat, wearing a hat. He is strong and tough and mean, making his living through collecting debts for the Wound Ravens in general, and Marv the Pawnbroker especially. Big Steve's crew are called the Easy 18's and mostly just follow Steve around, cleaning up the crumbs he leaves behind.

Steve always wears a bullet-proof vest and carries a Colt 1911. He prefers beating people down with a blackjack to using his gun, if it's practical.

Big Steve was badly beaten by vigilantes searching for Declan O'Toole in February 1934.

Big Steve was accidentally killed by Marv the Pawnbroker in a battle against vigilantes in June 1934
