Since launching in 2014, The Flash has become just as important as Arrow, if not more so, introducing countless concepts ranging from the Multiverse to time travel and a whole slew of characters that have all helped define and expand the Arrowverse.

Across three and a half seasons now, one thing that has stood out among the show's many successes has been its villains. Whether it's a hulking shark man, a telepathic gorilla, metahumans who can bend reality itself, criminals who have made due without powers of their own, or speedsters from different times and Earths, The Flash has consistently clashed with a number of antagonists from all walks of life of all different shapes and sizes that have pushed his heroism and his abilities to their limits.
