Colonel Kane (Photo: DC Comics) It's no secret that the Arrowverse's shows have family at their core, with the parents and siblings of main characters usually playing some sort of large role. With that in mind, it's pretty easy to see Colonel Jacob Kane being one of Kate's closest allies. Colonel Kane - and his various military exploits - has played a major role in his daughter's life, especially once she takes on the mantle of Batwoman. To an extent, Colonel Kane becomes Kate's "guy in the chair", helping remotely lead her on all of her different missions. Having Colonel Kane fill his comics-accurate role as Kate's command center, while simultaneously playing against the Arrowverse's existing tropes about that job, would be a pretty interesting set up. Plus, it'd be delightful to see Colonel Kane give characters like Cisco Ramon and Felicity Smoak a bit of a run for their money. prevnext

Red Alice (Photo: DC Comics) Another way that Batwoman could take the Arrowverse's family tropes into a new direction would be the arrival of Kate's twin sister, Elizabeth "Red Alice" Kane. Early on in Kate's life, Elizabeth and her mother are presumed dead after a terrorist kidnapping gone wrong. Years later, as Kate is working as Batwoman, she crosses paths with Elizabeth, who has since become one of the criminal leaders within Gotham City. Elizabeth, now mentally broken after the trauma of her youth, molds herself after Alice from Alice in Wonderland, and ends up being a pretty formidable foe for Kate. Not only would Elizabeth be one of the most stylistically-interesting Arrowverse Big Bads yet, but the longform storytelling of television would allow her and Kate's conflict to be taken into some interesting places. prevnext

Flamebird (Photo: DC Comics) Bette Kane, a.k.a. Flamebird, rounds out the Kane family members that we'd love to see on a Batwoman TV show. In the comics, Bette is an overachieving tennis star, who adopts the mantle of Flamebird as a way to meet Dick Grayson/Robin. While Bette's attempts at connecting with the sidekick are unrequited, she eventually realizes that she has a knack and a love for superheroics. Bette eventually joins the West Coast Titans, helping them quite a bit before returning to her normal life. Having Bette be involved with Batwoman would provide a nice connection to the BatFam and the Teen Titans, without having to introduce more prominent DC Comics characters. At the moment, though, it's unclear if and when Flamebird could make her way to Batwoman, as a character with that same mantle is expected to appear on the second season of Krypton. prevnext

Whisper A'daire (Photo: DC Comics) There certainly is no shortage of Gotham-set characters that Batwoman could draw inspiration from, but we think Whisper A'daire is one of the most interesting possibilities. Whisper was once an agent of Ra's al Ghul, who gave her immortality and the ability to shapeshift. She uses these powers to create a small legion of shapeshifting men, and to ultimately become a major ally of Intergang. Whisper has a skillset and M.O. that would fit the longform storytelling of a typical The CW season, while also giving the show a unique and intimidating female villain. prevnext

Bruno Mannheim (Photo: DC Comics) Of course, you can't have Intergang factor into the world of Batwoman without Bruno Mannheim playing some sort of role. In the comics, Bruno is one of the most well-known leaders of Intergang, helping give the group access to various forms of alien technology. Besides that, Bruno is just a pretty darn ruthless crime boss, who crosses paths with Batwoman in a weird (but particularly spoilery) way. Intergang has had a weird sort of tenure in the Arrowverse thus far, getting a fleeting mention on last season of Arrow, while still not appearing within Supergirl's Earth-38. Regardless of where Batwoman ends up being set, this certainly leaves a lot of potential for Bruno and his group to make their grand entrance. prevnext

Mad Hatter (Photo: DC Comics) As we've already mentioned, it's pretty safe to assume that Alice will factor into Batwoman at some point. And come on, Alice has to have a Mad Hatter. Jervis Tetch is a scientist with various mind-controlling abilities, whose aesthetic and persona draws inspiration from Alice in Wonderland's "Mad Hatter". As fans have seen within Gotham, Mad Hatter's M.O. can get pretty creepy at times, while also working within the storytelling confines of television. But since a version of the character has yet to debut in the Arrowverse, we can't help but wonder how he would factor into Batwoman. prevnext

Lucius Fox (Photo: DC Comics) One of the biggest burning questions surrounding Batwoman's Arrowverse arrival has been how the show will reference the rest of the BatFam, and what other existing characters will be in Kate's orbit. Granted, it's way too early to tell the answer to that question, but Lucius Fox seems like an interesting possibility. Lucius is easily one of Bruce Wayne's most trusted allies, playing a major financial role with the dealings of Wayne Enterprises. Lucius grows to play a unique role in Bruce's sort of double life, something that (to an extent) extends to the rest of the BatFam. Even if Bruce Wayne doesn't physically make an appearance to Batwoman, Lucius Fox would be an easy way for the series to bridge those two worlds, and possibly create an entirely new iteration of the character than what's been seen in the Dark Knight trilogy. prevnext
