Adventures of John: Heroes

Things are coming to a head. Rifts continue to open, threatening to tear the universes apart. I discovered the origin of the rifts, but I still need to find a way to stop them. But before I could, I was spirited away to yet another reality, this one home to some of the multiverse's greatest heroes. Begins after "Parallels", "The Doctor, the Daleks, and the Dragon" and "Winchesters"
