I know everyone and their mother thinks this location will be the Marvel Mangaverse (especially since that universe's Spidey appeared in Spidey Verse) but having seen the awesomeness of what they're doing with Kun Lun in the Masters of Kung Fu mini it reminded me of something from a few years back which out of hope I would prefer... the 5 Ronin Universe.
This had characters like Wolverine, Hulk, Punisher, Psylocke and Deadpool as master-less Samurai and there was a great story running through it all, so I would happily return to that universe if Secret Wars wanted to. Alternatively in a similar vein there was a what if issue where Daredevil was in feudal Japan which could easily slot into that reality.
What do you think, would you rather see Five Ronin, Mangaverse or something different for the Far East Domain?
