This article contains The Flash spoilers if you aren’t all caught up through episode 18 of season six.

Save for Season 1’s Eobard Thawne – who also happens to be Barry Allen’s most iconic nemesis – The Flash has often struggled to craft compelling villains. From Zoom to Savitar and both versions of Cicada, the bad guys on this show tend to be fairly one-note, with goals that are generally straightforward and often not all that interesting. Steal Barry’s speed! Murder Iris! Take over the world with a weirdo brain helmet! Yawn.

The Flash Season 6 has worked diligently to reverse this trend, first with Ramsey Rosso’s Bloodwork, a villain driven by a fear of death and his own mortality rather than a lust for power and now in Eva McCulloch, a woman trapped in an alternate dimension for six years, who just wants to get back the life she left behind.
