The
Punisher is (or was) a
Marvel comic book "
hero". I'm pretty sure he first appeared in a
Spiderman comic. The
Punisher goes around killing bad guys with automatic weapons and explosives. He'd be really popular in the
media during the
last few years.
Spidey,
on the other hand, always tries his best not to kill the bad guys, so he doesn't get along with the Punisher, whom he feels is a criminal.
Spiderman has a similar relationship with Michael
Morbius and maybe
Blade. Anywho, the Punisher's story is that some bad guys (maybe
mafia) killed his family. He vows to get revenge and probably kills them all. He then devotes his life to killing as many bad guys as possible.
There's a movie based on this character, 1989's abysmal The Punisher starring Dolph Lundgren. Another in the long list of Marvel movie failures.
