Not that Mephisto can't get punched up, nor that he hasn't been, but that particular showing was due to either the interference of God, or Mephisto himself intentionally allowing himself to come to harm to mess with the Hulk's head, whichever you prefer.on the earth-realm, mephisto is vulnerable to a good old right hook.
Whoa, what comic is that scan from?
Got to say I love the way Dale Keown portrays Mephisto.
