[Marvel/DC] Which Marvel characters would have a difficult time adapting to life in the DC universe and vice-versa?

* Drax would have a tough time without Thanos.  Maybe he'd eventually find someone else to arch, but it wouldn't be the same.
* Green Lantern would just be a guy once his ring ran out of juice.
* Batman would struggle, at least on the inside, because of his unhealthy relationship with Gotham.  He's Batman - he could have fixed Gotham years ago.  But he wants it to stay a little sick so it still needs him.
* John Constantine would be thrown for a loop, all of a sudden being in a universe where magic consisted of bright beams of light and 'Eyes of Agawhatsits' rather than dark dealings.  He'd soon find some marks and get on with things, though.  
* Reed Richards would receive a stern talking-to from Superman: "look, Mr. Fantastic, stop trying to invent solutions to this problem.  We pretty much just punch things until they go away in this universe, and it's time for you to get used to that."
* Wonder Woman would try to join the Avengers only to be told by Black Widow, "hey, you know the secret rule of female superheroes: only one woman per team.  And what's with the bathing suit?  In this universe we wear pants."
