Poyo is a walking crowning moment of awesome. His name even gets its own font!
After Amelia starts dating Tony, her ex-boyfriend harasses her by leaving racist messages on her answering machine. He later kidnaps Tony and forces him to eat the corpses of dead baseball players so that he can write a tell-all book about their sex lives. He doesn't realize that by eating the baseball players' bodies, Tony gains their talents as well as their memories. Tony eventually smashes his kidnapper's skull with a fastball.
In Issue 32 Tony finally stands up to Applebee after over 30 issues of constant abuse from him, blowing his top and telling him to fuck off, turning Applebee into a whimpering wreck in the process. In general, Tony's tribulations throughout the series (having his ear bitten off, demoted to traffic cop, almost tortured to death by Amelia's psycho ex-boyfriend and the brutal murder of his twin sister) appear to have toughened him up considerably.
