6) Alduin (The Elder Scrolls V: Skyrim)
Going by other colorful nomenclatures like “the World Eater” and “the Nordic God of Destruction,” Alduin is a reviled force of evil that leaves even the bravest Nord warrior with quivering knees and pee-soaked undies. Hoping to trap him within the timestream, the ancients used an Elder Scroll to rid themselves of Alduin once and for all... inadvertently sending him into Skyrim’s future. So now he’s their problem. Deal with it!
