Punisher/moon knight in Gotham sounds fun. Between the deranged soldier with a skull kiling everyone and the deranged merc dressed in white cutting people's faces off (as mentioned above) and cutting moon shapes into ppls foreheads I think batman would be missed in the Gotham underworld. Punisher cleans house then moves on and if he does kill moon knight then Gotham has constant protection lol.
I like the idea of reed helping mr.freeze and perhaps his wife. Maybe give him a job in a new future foundation. Sounds cool.
If Tony gets access to the fortress of solitude I'd like to see what he comes up with.
Hercules might find a daddy to love him in DC Zues. Don't think he can fight his brother Ares like in MU being rather out classed but Ares opinion of him most likely won't be much different from his marvel incarnation other than he wouldn't bother with him.
If Thor replaces superman his villains will seriously miss the weakness to red sun, radioactive rocks and lead. Metallo moves to a new location, lex commits suicide or needs closer magical allies/ability or it can be a losing battle of tech VS magic. Thor isn't a boy scout so the interaction determines what lex does.
Parasite would enjoy it, perhaps he can leech just the hammer?
Flashes rouge gallery would be happy. Didn't get to kill the flash but he isn't around to piss in their cereal anymore. After years of adjusting to fight super fast flash dudes like quicksilver will get hurt. So they might be on the happy side.
