Let's just assume that:
....the Namor, Wasp, Angel, Monica Rambeau/Pulsar/Photon, Centurious, Iron Man, Storm, Tiger Shark, Red Hulk, Wonder Man, Songbird, Black Widow, Electro, Winter Soldier, the Radioactive Man, Black Bolt, and Colossus we've seen over the last MU-time 2 years are skrull imposters:
Where are the real heroes and criminals?
HOW were they displaced, and when?
(Obviously not in the way the Space Phantom accomplishes it--by sending the real hero to Limbo for the duration.)
Where are they being held captive?
Anyone have any ideas on this?
I'm not sure yet, but there may or may not have been a hint in CAPTAIN MARVEL #3, where we saw Mar-Vell a prisoner of the Skrulls. Unless that was a Skrull being conditioned to be Mar-Vell.
