The End
Yeah it kinda' helps make more sense if you read the second half of the awesomeness that was The Superior Foes of Spider-Man series by Nick Spencer.
So good. So, so good.
But basically Boomerang steals a rare portrait of Dr. Doom....maskless. From there he's on the run, playing the Chameleon and the Owl against each other in a bid to keep from getting killed by both crime bosses.
It's every bit as entertaining as it sounds, unless I just under-sold the whole thing....
