Dario Agger

Dario Agger is the ruthless CEO of Roxxon Energy Corporation, Marvel's notoriously corrupt mega-conglomerate. A cunning and ruthless businessman, he possesses the ability to transform into a massive minotaur, making him a formidable enemy for Thor.

Few Marvel villains have made themselves as immediately despicable as Dario Agger, who burst onto the scene in 2014 courtesy of the formidable creative team of Jason Aaron and Esad Ribić in Thor: God of Thunder #19. A Modern Age schemer operating at the ruthless intersection of corporate power and mythological menace, Agger has proven surprisingly durable — accumulating appearances across more than a decade and turning up in titles like Immortal Thor, Thor, and Weapon H. He's the kind of antagonist who thrives in distinguished company, sharing pages with Thor Odinson, the Enchantress Amora, and others, which tells you everything about the weight class he punches in. If you're building out your Marvel reading list and want a villain with real staying power and a genuinely modern edge, Dario Agger is absolutely worth tracking down.
