Supergirl Characters Who Should Go To Other Arrowverse Shows

We learned from a joint announcement by The CW, Warner Bros. TV, and Berlanti Productions that Supergirl will end in 2021 after its sixth season. While the early announcement (and confirmation of an elongated final season) means Supergirl's creative team has ample time to craft a suitable farewell for Kara Danvers (Melissa Benoist), there's no reason to assume we'll never hear from the rest of these wonderful characters ever again.

There are an awful lot of other DC superhero shows in The CW right now, with at least one more on the way. So, here's what we're going to do: We're going to pick one Supergirl character for each show that we think could use a little more of that good Supergirl energy.

Three things: We're not including Black Lightning because, other than a very brief appearance in "Crisis on Infinite Earths," Jefferson Pierce (Cress Williams) and his series are still very separate from the rest of the Arrowverse shows. We're also going to leave out Green Arrow & the Canaries for the moment, because The CW has yet to confirm whether or not that spin-off will actually happen. And Stargirl feels like it's in another time and space entirely so we're keeping it off the books for now, as well.

With that out of the way, let's go show-by-show and talk about which Supergirl characters should go where.

To get it out of the way, we are assuming that Lex Luthor (Jon Cryer) will already be a part of the new Superman & Lois series that's coming to the CW in 2021. Luthor has always been Superman's chief nemesis, so we think it's safe to leave him off this list — he's too obvious.

That being said, if there's one hero who makes the most sense to join Superman and Lois Lane, it's got to be J'onn J'onzz, aka the Martian Manhunter (David Harewood). Just like Kal-El, J'onn is a bit of a refugee from another world. It makes a lot of sense for Superman and Martian Manhunter to protect both Earth and Mars. Plus, it's always important to have someone who can take out Superman should he ever go rogue. and frankly, Martian Manhunter is one of the few heroes who could get that done. Martian Manhunter is more than just super strong, and he can do more than fly — with psychic abilities and the power to pass through objects, J'onn J'onzz has a leg up on Superman in a few key ways.

Let's also be really honest: Superman and Martian Manhunter teaming up is a chance to bring more Justice League Unlimited vibes to the live-action world. If ever there were a DC adaptation from which Superman & Lois could pull to make fans go absolutely wild, it's Justice League Unlimited.

It's hard to say for sure how Supergirl's story will end, but if the goal is to make it so, in universe, it makes sense that we won't see Kara Danvers anymore, there's a solid chance she'll be leaving Earth. Heck, she may even be traveling to the future to be with Mon-El! The point is, without her super sister around, Alex Danvers (Chyler Leigh) is going to be super bummed!

While we can all appreciate that Alex has a supportive, loving partner in Kelly Olsen (Azie Tesfai), it would make sense that Alex would still need to work out the frustration of not having her sister around. How could Alex have a bit of an extended lost weekend without Kelly feeling like she'd been ditched? Well, time travel could help with that problem. You know who has a time machine and could therefore drop Alex off moments after she left no matter how much time had actually past? The crew of the Waverider on DC's Legends of Tomorrow.

You might be thinking to yourself, "Didn't Alex have a surprising tryst with captain of the Waverider Sara Lance (Caity Lotz)?" She did! The strength of Legends of Tomorrow, however, is that all its best humor and drama comes out of how awkward its crew is all the time. If the Waverider can endure shapeshifters looking like lost loves and love triangles involving alternate universe versions of deceased characters, then Alex Danvers can handle traveling around with Sara Lance.

Alex Danvers is a bit of a control freak. If anyone can cure her of that and get her out of a funk, it's the misfits of DC's Legends of Tomorrow.

When the DEO lost Winn Schott (Jeremy Jordan), Brainy (Jesse Rath) was there to take up the mantle of the resident computer wizard. On The Flash, there are sometimes conversations as to whether or not Cisco Ramon (Carlos Valdes) will keep on being a regular part of the show.

Similarly, Caitlin Snow actress Danielle Panabaker (much like Melissa Benoist) had some of her filming schedule impacted by a pregnancy. While she's confirmed she'll return for The Flash's seventh season, it certainly wouldn't be unfair if Panabaker decided to renegotiate the number of episodes in which she'll appear during the first year of her child's life.

We also know that Ralph Dibny (Harley Sawyer) won't be back in any major way for the foreseeable future. Dibny was often a source of comedy, and Ramon and Snow are the brainy types — Brainy is both a source of comedy and his name is literally Brainy. We're calling it: The Flash needs Brainy.

Brainy needs The Flash, too. Brainy is an entity out of time who sometimes has to deal with alternate sides of himself. Barry Allen (Grant Gustin) sometimes travels in time and understands the emotional whiplash of that experience. Also, Caitlin Snow is sometimes Killer Frost and so there's some real camaraderie for Brainy there as well.

Could you imagine how much fun Cisco and Brainy would have together coming up with super villain names? It's a no-brainer!

Batwoman, as a show, is about to have a major shakeup. With Ruby Rose out as Kate Kane and a new Batwoman taking her place in the form of Ryan Wilder (Javicia Leslie), it's hard to guess just where the series may take its audience.

Finding the courage to put on a mask and protect a city of people is hard. Being a queer, Black woman a lot of those same people might not want to protect in return makes the responsibility that much harder. While Ryan Wilder will likely find some support from Luke Fox (Camrus Johnson), Sophie Moore (Meagan Tandy), and Mary Hamilton (Nicole Kang), she won't have anyone else in her immediate corner that knows what it's like to be a vigilante hero.

You know who has a lot of experience being a masked hero that protects a lot of people who wouldn't do the same in return? Nia Nal, aka Dreamer (Nicole Maines). As the first transgender superhero, Dreamer has to cope with similar struggles and code switching in order to navigate the world day-to-day. Knowing how to do that while also being a superhero means Nia could offer a real helping hand to Ryan Wilder.

While we'd love to see Dreamer on her own show, just imagine how cool it would be for her precognitive visions to be translated through the gothic world of Gotham City. We've been so used to seeing Dreamer's dreams through the lens of Supergirl's more blue-skied filter, so it would be thrilling to see the darker tones of those visions through the inky darkness of Gotham's often-nightmarish hues.
