There's a reason dude is the only real recurring villain in the Marvel movies—he's just that magnetic on screen and has more than enough layers to keep you coming back for more. While Thanos was all prelude, Loki sat comfortably atop the throne. He's evil out of lifelong insecurities; charismatic while still posing a real threat. He electrifies every scene he's in, even before he showed his hand in the first Thor; he is the main draw of the first two Thor solos, and 2012's The Avengers. Essentially, Loki is the anchor of Marvel's Phase 1 but by Phase 3 he was its twisted heart. —Frazier Tharpe
