Which Villains The Flash And Supergirl Will Face During The Crossover Episode

TV shows based on comics are just plain fun, and rarely are they more fun than when they get to cross over with one another. The long-rumored crossover between The Flash and Supergirl will be something entirely new as CBS will import Barry Allen from The CW for an evening. Thanks to Flash star Grant Gustin, we already got a glimpse of Barry and Kara suited up together. Now, we know which villains the duo will face together: Livewire and Silver Banshee.

Judging by the images obtained by Coming Soon, Livewire and Silver Banshee will be the perfect pair to cause some serious mayhem for the good guys in National City. It's hard to pick which of the women looks creepier, but it's definitely safe to say that two are much scarier than one in this case. Barry may get the shock of his life - pun slightly intended - when he lays eyes on Livewire and Silver Banshee. We've already seen what the former is capable of as a solo act.


Livewire – also known as former radio DJ Leslie Willis – was played by Brit Morgan in the fourth episode of Supergirl. After a freak lightning strike, she gained the ability to manipulate electricity and decided to use her new skills to take down her former boss. She was ultimately defeated by Supergirl and locked away by the DEO. But apparently not for long enough.

Silver Banshee

Silver Banshee is currently known on Supergirl as Siobhan Smythe, the CatCo employee played by Italia Ricci. The only powers that Siobhan has displayed so far are super-effectiveness and super-competitiveness, but she’ll be channeling her screaming beast side sometime in the near future.

We may not have any details about how these evil ladies are going to join forces, but we can definitely be glad for Kara that she’ll have some super backup to battle them. Details also happen to be scarce about just how and why Barry makes a dash to National City for the crossover. There haven’t been any big hints dropped on the CBS side, but a recent Flash episode on The CW that saw Barry traveling to a parallel world featured a quick clip of Supergirl in flight. We may in fact learn that that Kara Danvers lives in an entirely different world than that of Barry Allen and all the other Earth 1 masks in The CW’s comic lineup. Separating their worlds would be a great way to let Barry and Kara meet without raising the question of why all of the CW heroes aren't wanting to call up Supergirl whenever things get too out of hand.

Barry Allen won’t be racing over to CBS to help Kara until March 28, so we still have a wait ahead of us until we see the Flash and Supergirl united against common enemies. Luckily, the next few weeks should see Siobhan getting a lot nastier, so there’s plenty to look forward to. Supergirl airs on Mondays at 8 p.m. ET on CBS.
