The Fallout series has never been shy about referencing its many beloved characters and locales. The recent iterations of the franchise have been laden with nods to games gone by, whether they've come in the form of fully fledged characters or merely through a cleverly placed Easter egg: these allusions tie the post-apocalyptic wasteland together, they're one of the many things that makes it feel so alive. There are characters throughout the Fallout universe that for whatever reason, have managed to imprint themselves upon the memories of countless gamers. It's not always the most impactful characters sometimes it's the most bizarre. However, bringing a character from one world into another is no mean feat, and getting it wrong can taint the character indefinitely. This being the Fallout universe almost anything is possible, and with all the games being set within a reasonable number of years from one another, it's entirely likely that characters from the original Fallout games could be seen standing alongside figures from Fallout 3 or Fallout: New Vegas. Even after investing hundreds of hours in these worlds, there are still story-lines that need tying up, themes that need exploring and friendly faces we'd love to see again; human or not.
