The multiverse theory -- where all possible worlds exist as multiple universes -- has become an important part of the DCU, and some of the biggest DC events in recent history, like "52" and "Final Crisis."
Now, the concept has made its way into "Family Guy," where Brian and Stewie went tripping through their own version of the multiverse in the season premiere. But where the DC multiverse contains the world that's actually the Golden Age of comics, or the world where Superman is a communist, "Family Guy" goes hopping through Disney Universe, Flintstones universe, "Robot Chicken" universe, Washington Post political cartoon universe, and the Dog universe where humans are pets.
The full episode is online at Hulu, and after the jump.
