Probably DC Comics. And it depends what my role in this universe would be. But knowing my luck I’d just be a random civilian that gets wiped out during the latest rampage by Atomic Skull or something. But at least everything gets reset every few years, so that I could live again to be super villain fodder another day.
The only two that I ever still make use of are XDA for custom firmwares and other Android related shit. And Pokecommunity for the ROM hacking / decompilation stuff.
