Arrow: 10 Villains Who Need To Appear In Season 4

By James Hunt /

8. Black Manta

Black Manta is traditionally an Aquaman villain, although he has faced off against the Green Arrow as well. He wears a suit that allows him to survive underwater, and also gives him enhanced strength. He€™s highly intelligent and skilled at hand-to-hand combat. His story doesn€™t necessarily require Aquaman to work, so he could be introduced on Arrow, and having a threat from the sea would be something very different to what we€™ve seen so far, and could even tie into Oliver€™s time on the island.
