Guesses on Batman's fateHe's only been stated to be "missing", which could mean a lot of things. So, let's speculate on what happened to him.
- Option 1: He's dead. It could be that they Never Found the Body, and Batman has died before in the comics (i.e., Superman: Red Son, Final Crisis).
- If this is the case, perhaps Alfred and Robin (whoever it was at the time in the Arrowverse) died alongside him.
- Option 2: Batman went away for training with the League of Shadows, feeling he went out of shape; said training took much longer than he expected. It would make him leaving without telling anyone not be a mistake on Bruce's part.
- Since this would be the Earth-1 League of Assassins, they could of abducted him to convert him into an unwilling successor to Ra's al Ghul.
- Option 3: This Batman finally retired.
- Option 4: This Batman is a much more active member of the Justice League.
- Option 5: He went insane after the death of yet another loved one, like Jason Todd or even Alfred.
- Option 6: His back was broken by Bane. He was subsequently shuffled away to one of the best hospitals in the world.
- Option 7: Batman was brainwashed to become Owlman by either the Court of Owls or the world-hopping Injustice League.
- Option 8: In light of what little we learned in Elseworlds, some of these options just would make sense, since Bruce is said to have left... with no one he knows having any idea as to where, so he likely didn't just abandon Gotham because he wanted to do it. He was driven out, or coerced to leave by someone very, very dangerous. Said threat forced him to not let anyone know where he is, hence why Kate is just as lost as anyone else.
Other members of the Bat Family that will show upAnd since we're guessing what Batman's fate will be, let's also speculate about the rest of the Batfamily. While Robin would probably be off the table as well if Batman's death is due to him being Exiled from Continuity due to the DCEU using his role, perhaps they'll use other members
- Oracle and Spoiler: Assuming that Batgirl is Exiled from Continuity due to the Batgirl movie the DCEU supposedly has in the works, that would mean that both characters would still be available (especially since I doubt they'd have Stephanie Brown be the first person shown on-screen adapting the identity of Robin).
- Azrael (Jean-Paul Valley): Could be used as an Anti-Hero Substitute for Batman, assuming he's dead.
- Batman Beyond: It's only been stated that they can't use Batman. However, Terry isn't Bruce Wayne, and considering the Arrowverse has had crossovers between dimensions, time travel wouldn't be too out of the ordinary. Perhaps they'll reveal that the "Batman" that is missing is in fact, the Michael Keaton one (the present day one having retired simply because of how old he is), and he's been training Terry.
- Tim Drake: At least one Robin is confirmed to exist in this continuity. Odds are that Batman's career is far enough along for Dick to have already become Nightwing and Jason Todd to die and become Red Hood. Assuming that Jason's demise isn't what drove Bruce out of Gotham, then he likely had begun training Tim Drake by the time he left. If so it remains to be seen if he also gave up on being Robin for some reason, or if he left for the same reason Bruce did.
The show will be set on Earth-38Let's face it, Earth-1 is getting really, really crowded. Besides, Kara needs prominent hero besides her cousin she can regularly team-up with without the need to cross to Earth-1, plus she and Kate can regularly team-up like Superman and Batman do since the Arrowverse obviously can't use those two. And also, Kara and Kate's crossovers can highlight their different approach in heroics the more classic DC way (only Gender Flipped).
- Seemingly Jossed by the first hour of Elseworlds, which sets up Batwoman as existing in the Gotham City of Earth-1.
Earth-1 Maggie Sawyer will appear, played by a new actressWe already know that different versions of the same person can be in the different universes, so its possible that we could see the Earth-1 Maggie Sawyer, played by an actress who more closely resembles the comic Maggie Sawyer.
- That would explain why it's on Earth-1 instead of Earth-38 considering that Earth-38's Maggie Swayer's actress wasn't interested in committing to the show. Hopefully they will keep the race lift though.
- There's two issues with this idea; the Arrowverse shows tend to drop characters entirely after the actor leaves or they introduce another character who can fill the same role and they like to have the alternate versions of characters still be played by their primary actor (major exceptions tend to be for wanting cameos from actors with ties to other adaptations of the source material). Throw in that it'd be kind of confusing for a general audience who isn't familiar with the comics' Maggie, they may just stick to using some different love interests for Kate.
- A bit of evidence supporting this is that Kate and Maggie have the same jacket.
- Maggie will be played by the same actress, now that Supergirl's universe merged with the Arrowverse.
Kate was classmates with Lucy Lane.The Earth-38 version of Lucy attended West Point, so if she exists on Earth-1 at all, this is a possibility.
Mary will turn out to be a Canon Character All AlongBut, in a twist, she may not be a counterpart to Bette Kane, but to another, more obscure character, with elements of other characters.
The Penguin is closer to the version from Batman Returns than anything elseThis will justify why he's in Arkham Asylum; he's bitten people and lead clowns who lived in a sewer!
Kate and Sophie will fight each other, possibly in a flashback as cadets.Instagram videos show both Ruby Rose and Meagan Tandy going through boxing drills; while that could be just general warmups or similar, both Kate and Sophie were boxers at West Point in the comics and have sparred on-panel.
Catherine will recruit some of the Crows to eliminate Batwoman, without Jacob's knowledge or permission.According to her character breakdown, Catherine is unaware that Kate is Batwoman, and also considers Batwoman bad for business. And since Jacob probably is aware of who Batwoman is, he won't agree to using the Crows against her.
Chuck Dodgson is a mole within the Crows, working for the Wonderland Gang.Chuck is short for Charles. Charles Dodgson is the real name of Lewis Carroll.
- Basically confirmed in the first trailer.
Any scenes in the pilot taking place at West Point will be filmed on location.Though not confirmed officially or unofficially as one of the filming locations, a few pieces of evidence suggest this is the case:
- The pilot's shooting schedule overlaps with West Point's spring break.
- During the week that this filming would occur, both Ruby Rose and Meagan Tandy (the only members of the main cast needed for such scenes) were unaccounted for in any detail on social media; by contrast, most of the others (Camrus Johnson, Nicole Kang, and Rachel Skarsten) were all definitely still in Vancouver.
- Rendered a bit moot, since the real Academy has been changed to a Fictional Counterpart, Point Rock Academy.
Other heroes and supporting characters who may appear or be referenced
- Vesper Fairchild, since she's was confirmed to exist in Elseworlds.
- Confirmed...sort of. She's been confirmed to be a cast member as The Voice, portrayed by Rachel Maddow.
- Harper Row/Bluebird
- Julie Madison
- Lucius Fox
- Jason Todd/Red Hood
- Vicki Vale
- Helena Wayne
- Chief O'Hara
- Dr. Chase Meridian
- Philip Wayne/Kane
- Tim Drake/Robin/Red Robin/Drake
- Stephanie Brown/Batgirl/Spoiler
- Julia Pennyworth
- Jack Ryder/The Creeper
Kate owned or owns a dog.As Kate, Ruby Rose's real-life tattoo of one of her dogs on her left hand has not been altered, so perhaps that will be a trait shared with the character. This could also lead to Ace the Bathound's introduction.
Bruce left the Batcave and everything in it to Kate in the event he was unable to be Batman anymore...... but she only discovered it recently. The trailer seems to indicate she already knew Bruce was Batman somehow, and it makes a decent amount of sense for her to inherit it: she's family and of a similar age, she's local, and she has at least some level of relevant skills. Since she also runs what's left of Wayne Enterprises as of Elseworlds, perhaps the two are a package deal of sorts.
- Jossed. Kate only discovers that Bruce Wayne is Batman in the premiere episode, and has to strong-arm Luke Fox into letting/helping her use Batman's equipment for her own ends.
Batman has been kidnapped by one of his arch foesIt will later be revealed that Batman is being held captive by either Ras Al Ghul or Bane in a foreign country. It'll be up to Batwoman to rescue him.
Luke will only start to become Batwing in Season 2The whole "flying armored suit" effect may overshadow Kate as Batwoman, so they'll hold off on introducing that element for at least a while.
There will be a Written-In Infirmity regarding Kate.Sometime between the pilot and the production of early first-season episodes, Ruby Rose had emergency surgery to correct herniated discs in her neck, leaving her with a noticeable scar on her throat. This scar could easily be explained in-universe.
- Perhaps as a new tattoo gone horribly wrong "Never using that tattoo artist again." as Kate is obviously into body art. Or perhaps the tattoo excuse would just be for those unaware of her secret identity to explain a scar from Alice getting lucky with her knife in a fight early in the season.
There are multiple batcaves in GothamKate only found one of them. Notice you don't see any of the batmobiles. Plus the cave in the show is a bit small compare to the ones we see in other media. The one true batcave is under Wayne Manor.
Jacob will become the Two-Face for this universe.Alice refers to him as a "white knight", similar to Harvey Dent in the Nolanverse.
Tyler is gay.He and Sophie married as a way to mutually defuse suspicion about themselves.
- Jossed, as seen in "Down, Down, Down", Sophie never even told him about Kate.
Calendar Man will be a future Big BadDue to being very smart and manipulative, this will force Kate to develop her detective skills, which could make for an interesting arc for her character. It also gives them an excuse for episodes set on holidays, which rarely aren't a treat for the audience.
Damian Wayne exists.He'll either already be Robin or take the mantle on when he arrives in Gotham. He'll be trying to solve where Bruce is.
- Alternatively, Bruce left to raise Damian on his own, rather than risk him being targeted by enemies in Gotham.
Alfred is deadIt wouldn't necessarily be the cause of Batman's vanishing, but it probably didn't help.
If Catwoman appears, she won't be Selina KyleInstead, the role will be given to Holly Robinson or Eiko Hasigawa. Kate could have Foe Yay with them, which could lead to jokes about how she's really getting a hang of taking up Batman's role in the city, and, more seriously, a love interest other than the married Sophie.
The real mystery is...Catherine wanted to kill Jacob's wife, because she was in love with Jacob and thinks his wife "stole" him from Catherine. So she made sure Jacob's wife has gotten a poorly-designed car and hired the Joker to kill her. But she probably didn't count on her taking her daughters. She found out Beth survived but had to plant false evidence of her death to prevent anyone from learning of her scheme. As for Batman, he's been trying to discover the truth about what happened that day, and suspect that the Joker is connected. In his mission to apprehend the Joker to get him to talk, his partner, Jason Todd, got killed as a result. This has taken a toll on Batman, and led him to leave Gotham.
Beth/Alice was mentored by one of Batman's villainsWhile there's a chance that she fell into this persona all on her own, the fact that she never surfaced in the time between her accident and the present might hint that something more happened to her, most likely in the house she stumbled into in the flashback from episode 3 (unless it exists solely in her dream). The options:
- The Joker. It'd be an easy parallel to him and Batman, with Alice and Batwoman being each other's greatest foes. Also, Joker has dealt with face removal before/
- Professor Pyg: Just as mad as the Joker, and just as likely to have someone's face in a sink in a house in the woods.
- The Mad Hatter, for obvious reasons.
- The Riddler: Alice's penchant for riddles and references to Alice in Wonderland may've been inspired by Nygma. The fact that he's not only referenced in episode 3 but is mentioned to have figured out Batman's true identity may also hint that he's playing a larger role.
- The Cluemaster. Another riddle-heavy villain, but here he's raised Beth as a replacement for his own daughter, who has already become the Spoiler and foiled him too many times. Plus it throws another log on the fathers-daughters-and-sisters themes that the show has going on.
- Alternatively, Beth was found and molded into what she is now by The Religion of Crime, a cult she was a member of in the comics. The membership of the group will receive an upgrade to churn out multiple foes for the future and take the place the League of Assassins may have played if they hadn't been so heavily used in Arrow.
The Joker is deadAfter the Clown Prince of Crime caused so much harm, including the results of the school bus attack and possibly shooting Barbara Gordon, Batman killed the Joker in a rage during a confrontation. This Batman had a "no killing" code, and it shook him enough to partially contribute to why he left Gotham. Harley Quinn went after Batman for revenge, but was captured by ARGUS.
Mary isn't Bette Kane's adaptationThey've instead gone the Decomposite Character route.
Season 2 will see the rise of the "We Are Robin" CollectiveNot only is Batman gone, but whatever Robin(s) he had at his side are gone as well. As Kate navigates her way towards becoming the new face of justice in Gotham, a group of disaffected teens will either come to her aid or challenge her position. This will pave the way for Duke Thomas' introduction and he'll either join Kate as her own Robin, or assume his comics identity of The Signal.
Bat-Mite will appearAt first he'll decry Kate as an inferior replacement for Bruce, who he was expecting to meet when he came here from his home dimension. But as he follows her along on a days work he'll come to respect her. By the end he'll give a Take That, Critics! speech similar to the he gave in Batman: The Brave and the Bold.
- To keep the grim-and-gritty realism, Bat-Mite will be just in Kate's head. Everyone will think she's crazy, seeing her talking to nobody. Near the end of the episode, Kate will still wonder whether or not he was real. He will look like a chubby Manchild fanboy wearing a costume resembling the Adam West Batman.
Post-Crisis, some of Batman's Rogues Gallery will be played by their Gotham counterpartsWhile there's been nothing said about Gotham characters appearing in Crisis itself, there's not much stopping them from showing up after if their Earth is one of the ones fused with Earth-1. They don't necessarily need to be huge characters, but audiences would probably appreciate appearances from the more well-received characters like Riddler or Penguin.
Luke's subplot, and potential path to becoming Batwing, will involve him trying to find his father's real killer.
Mouse's father is deadMouse and Alice murdered him.
- His last words will be how he truly finds his son repulsing.
- Jossed. Cartwright is alive, using flesh masks to hide his true identity.
Alice will have a redemption arc and sacrifice herself to save someoneAlice/Beth will die by the end of season 1 (or season 2), but not before redeeming herself and forgiving Jacob and Kate. She will sacrifice herself to kill Mouse. Alice will die with a smile knowing her family have forgiven her for her crimes.
Tyler will pull a FaceHeel Turn.He hasn't gotten over Sophie keeping her lesbian past a secret from him and knows she still has feelings for her. This, and other circumstances, will put him in a path to villainy. In a Took a Level in Jerkass moment, he will tell Sophie's mother about her sexuality.
- Probably jossed, as he decided they should separate.
Possibly related to the theory above, Tyler will turn out to be a Canon Character All Along.
There will be an episode solely focused on Kate's training before she became Batwoman.
Catherine really did provide weapons to criminals, and the Joker used some of them during the rampage that resulted in the car crash that killed Gabi Kane.
At some point, Mary will seek out her biological father
Bruce Wayne will appear in season 2Similar to how Superman showed up in season 2 of Supergirl (2015). He won't wear the suit, but he will play a supporting role. Similar to his appearance on Titans (2018).
Mary will either become a super hero or an anti-villainEpisode 8 feels like an origin story for Mary. Having your step-sister "favor" her murderous biological sister over you and your mom being murdered by that same sister could drive a person insane. She could develop a deep hatred for Alice and try to hunt her down.
- Jossed. Sophie has basically taken over, or at least isn't being hindered by anyone in such a way.
Sophie will have a Character Arc similar to Renee Montoya's in the comics.Which involves her being outed, her mother finds out and disowns her, leading her to a drunken mess before coming back up. She'll quit the Crows and become a Vigilante Woman.
How the merge into Earth-Prime affected Gotham
- Bruce knew Clark, like on Earth-38, but still disappeared. The fact that Superman's efforts to find Batman were unsuccessful contributed to the belief that he abandoned Gotham.
- Alice gained powers of some kind, making her even more of a threat.
- The Sange, the white power gang from Freeland, have a "chapter" in Gotham. A member, or even the leader of this faction, is the one who killed Lucius Fox.
Reagan will reappear.
- Seeing that she's proved pretty popular with fans despite a small, rather ancillary role, she will make a reappearance. Either she and Kate will rekindle their relationship (seeing that Kate's not making any progress with Sophie so far) or she'll undergo a FaceHeel Turn and become a supervillain (perhaps with mind powers).
The Alice who appeared in Kate's office is the one from Earth-99
Luke will be all in on killing Alice following Beth's death
Alice will, in an ironic twist, end up killing Dr. Cartwright as Dr. Campbell
- Even more ironic is that he'll be surprised because he thought he killed her, when he actually killed her counterpart from another Earth.
Mouse will become Hush.The only hint to this is when his dad said "Hush now, son."
Alice now wants Gotham to burn because Kate chose Beth over her.
- Jossed, but she probably does for real, as payback for Kate's betrayal in "Through the Looking Glass".
August Cartwright was directly responsible for the "accident" that scarred his son's faceWe don't actually know how or why Mouse's face looks like that, only that it happened in some unspecified "accident". We've seen what an utter monster his father is, and how he ultimately used the facial disguise technology to assume the life of Dr. Ethan Campbell for prestige that he felt he deserved. I feel like—and it's possible that even Jonathan himself does not know this—that August deliberately burned his son's face, either as an impulsive act of abuse or as part of a Long Game to try and justify to others why he needed to make the masks to begin with; to claim that it was to heal his son's face, but really for himself to take over any life he pleases, demonstrating that he in fact is the real Jane Doe of the Arrowverse, not Mouse.
