Who is The Big O? All I know is that he's from Long Island, New York and he used to wrestle as Adamus Davidus. I read somewhere that in 2011, The Big O appeared on WWE as the bodyguard of Zack Ryder (apparently, he and Ryder are friends). The Big O is campaigning to get signed to WWE or at least FCW. In the meantime, he's been wrestling in the New York area and has dropped a couple of short videos on YouTube (watch them here and here).
