CAN SPIDER-MAN SAVE J. JONAH JAMESON FROM A RELENTLESS ASSASSIN?! He's the public face of a city of 8 Million -- and only one of them has to be pushed over the edge to take his life -- but who is the Extremist? And why does he want to kill J. Jonah Jameson? And why does he claim to be Spider-Man's greatest ally? Brought to you by Fred Van Lente & Javier Rodriguez. Meanwhile, JACKPOT RETURNS - and the streets of the Marvel U will never be the same! By Webhead Veteran Marc Guggenheim and Sana Takeda (MS. MARVEL).
