7) Enter Zoom (Season 2, Episode 6)
It’s hard to argue that season 2’s big bad Zoom lost a lot of his appeal once he whipped off his mask and was revealed to be the fake Jay Garrick. Nothing against Teddy Sears’ performance, but the character just had more power as an unknowable and inhuman force. The best episode that demonstrated this was the first time he and the Flash came to blows, in “Enter Zoom.”
[zergpaid]Most of the episode, where the STAR Labs gang train Linda Park up to impersonate her metahuman doppelganger Dr. Light, is quite light-hearted and fun. The climax, however, tips the scales completely the other way in a pretty dark sequence that shows just how formidable Zoom is – paralyzing Barry and showing the people of Central City their broken hero. If only he had stayed this way, then Reverse-Flash would have had a run for his money as the best Flash villain.
