15 Best TV Villains In The Marvel Cinematic Universe

15. Nobu

Appeared In: Daredevil

Though Nobu's body was last seen burning, chances are strong that fans will retroactively learn more about him - and the importance behind Black Sky - sometime down the line, perhaps when Iron Fist arrives.

As it stands, though, and despite what little the first season of Daredevil divulged about the mysterious character, Nobu proved to be one of the vigilante's most dangerous challenges along his journey to bring down Wilson Fisk.

The two engaged in a brutal fight that peppered the runtime of "Speak of the Devil," with Nobu nearly succeeding in killing Matt before the latter gained a last-second upper hand. Their duel served as one of the first season's many highlights and solidified Nobu's status as a true threat.
