The Fallout franchise is arguably one of the most iconic post-apocalyptic series out there, and it owes a lot of that success to its unique and bizarre setting. Unlike a more conventional apocalypse, the irradiated wastelands of Fallout play home to some truly distinctive creatures. Monsters like deathclaws, cazadors, and super mutants are some of the most immediately recognizable aspects of the series, and a big part of its appeal.
