Once upon a time, champions emerged to fight the evil plaguing humanity. They fought for all that was good in the world. They were kind, generous and self-sacrificing. They were heroes. These are not those heroes. Meet Hawkeye: ladies man ("ladies man" because the ladies love to hate this man), mighty marksman and, most importantly, Avenger. He's the only guy on the team without any powers, though. Then there's Deadpool (Mr. Deadpool to you), the regeneratin' degenerate. You can shoot him, stab him, and punch him right in his face, but nothing can keep the Merc with a Mouth down. What do they have in common? Halloween in Brooklyn, and a S.H.I.E.L.D. espionage mystery that has both heroes racing the clock! But will Deadpool and Hawkeye kill each other before they figure it out?
