Okay I know it's just a title but something that is constantly bothering me is how DC does a Crisis to retcon something and it's always something with the multiverse. I feel like the multiverse is overdone and boring at this point. I'm sure they've done something like this before, but I'd like an event similar to Secret Invasion with the focus being on Martian Manhunter. Like it's discovered young heroes have been replaced by green martians and that the Martians have been plotting to slowly take over Earth for generations meddling with major events and insinuating themselves into various groups and organizations. I like the idea of Green Martians returning because they in current continuity are extinct except for J'onn and his brother so I like the idea of his people returning and him being torn about what side to be on.
