While villains like Loki, Thanos, and Winter Soldier have been very well received in the MCU there are plenty of villains the Avengers have faced that have not. Is how well adapted they've been from their Marvel Comics source material into the Marvel Cinematic Universe have an effect? After ranking the heroes of the MCU, now it's time to rank the supervillains by how well they've been adapted by rating their costumes, characterization, and continuity and I've found the bottom 20 worst adapted of all of them.
