The Flash: 37 villains he's battled

Image for The Flash: 37 villains he's battled

While the first two seasons of Arrow were an extremely grounded affair (gritty enough to feel right at home on the big screen with much of DC's feature output so far), it opened the door to a meta-reality when it served as a launching pad for the spin-off series, The Flash. Starring Grant Gustin in the title role as well as alter ego Barry Allen, from out of the gate the series embraced its comic book roots, delivering larger-than-life adventures filled with metahumans – most of whom, just like Barry, were transformed from ordinary humans into something quite extraordinary due to an exploding particle.

What follows is a guide to 34 villains that The Flash has gone up against over the course of the show's first two seasons.
