In Punisher #28 and 29, Pun takes on Dr. Doom as part of the Acts of Vengeance event.
Mike Baron does a great job at the dialog between Kingpin and Doom, who are trading enemies for the Acts of Vengeance event.
Doombots attack first. Then, a giant robot.
I don’t really like Punisher fighting giant robots–at least I don’t like it most of the time. But as far as “mainstream” Punisher stories go, this is one of the better ones.
Baron also does a great job at the endgame.
After some Avengers appearances (really just cameos), we learn that it wasn’t Doom after all, but Kristof–the boy who thinks he is Dr. Doom, but really isn’t–and we see the actual Doom’s love of art as his downfall. On the top of Punisher’s van in the picture above, is a painting of Doom’s parents, which Punisher stole from Doom’s castle and used as bait to draw Doom out.
Ego and art are both recurring themes from Fantastic Four, making this a well-handled crossover that pays attention to the source material.
