X-23
IronFist
Spiderman
Mr. X
In that order. I'd go play sports, likely a combat sport like MMA, and get rich. Then live my life after retiring as greatest of all time. Laura is first because the passive benefits are too great to pass up. Never getting sick, healing all my sports trauma right away, staying in my physical prime for a long time, etc. They could all get me to the same spot, but say, with Mr. X, a broken arm or the flu still sucks.
they are not even equipped to fight someone like ocean master or mera. Id pick havok then join the suicide squad maybe
they do better in new 52 dc, pre flashpoint wise- titans or teen titans were ridiculously stacked, not to mention jsa and jla
all the people on the list would do great in a city like gotham, where most are street levelers, these marvel heroes are way above joker riddler etc as long as they play it smart they can be a kingpin if they choose to be villain.
because let's be honest, anywhere from metropolis to central city, you are just lookin for getting locked up.
someone like silver surfer, thor or adam warlock are good addition to dc earth. I can't think of anyone like them. hulk would just be a good guy version of doomsday
even doctor strange, there is already a doctor fate
