Krazy Kat

I'm skeptical of listing Krazy Kat. Krazy Kat's creator described Krazy Kat thus: "something like a sprite, an elf. They have no sex. So that Kat can't be a he or a she. The Kat's a spirit—a pixie—free to butt into anything". To me, being sexless is different than being non-binary or agender. You could easily argue that Big Bird is sexless or any number of ambiguous cartoon animal characters. (Yes I know that Big Bird is canonically male, but still.) This is another reason why I think our inclusion criteria should include some mention of the character having a human-like experience of gender, but I suppose that's a bigger discussion. What do folks think about the inclusion of Krazy Kat specifically? Nosferattus (talk) 02:17, 11 July 2024 (UTC)

Hmm. You make a good point. I'd be ok with removing it. The inclusion criteria should surely be updated. I'd be willing to revisit that again and propose possible changes (I know previous discussions were not very fruitful, but I'd be willing to try again). Historyday01 (talk) 17:11, 24 July 2024 (UTC)

I think "sexless" could mean agender, asexual, or both. The author's words "can't be a he or a she" sound like a nonbinary, agender character to me.

Perhaps our inclusion criteria should allow for any characters that are sapient/sentient, regardless of species or corporeal nature. MichaelReed481 (talk) 18:41, 24 July 2025 (UTC)

Recent edits

@User:Nosferattus, while I appreciate your edits, generally, I have to disagree with your recent removal of the words "with sub-pages for characters in anime and animation" as related to lists of lesbian and bisexual characters, specifically the following pages: List of lesbian characters in animation and List of bisexual characters in animation. I have proposed a possible compromise with my recent edit (I would also be ok if these two pages were moved to the "See also" section). Otherwise, you claimed in an edit that "the bit about Yivo using neopronouns in the show is essentially just a joke making fun of neopronouns" and that Yivo belongs to "genderless species or class of being". I have reversed that edit. I request that you provide sources to back up these assertions, especially the first assertion and would further reason the onus is on you to prove these assertions since you made these claims. Otherwise, if reliable sources are not provided, I would not support the removal of Yivo from the page. Historyday01 (talk) 19:31, 30 July 2024 (UTC)

I just removed them because there are several other sub-lists for List of fictional lesbian characters and List of fictional bisexual characters. Why are we only mentioning the animation sub-lists? And if we list all of them, the sentence becomes an unreadable nightmare. Nosferattus (talk) 19:41, 30 July 2024 (UTC)

Honestly, they were only listed that way because that's how I originally constructed the page (and I realized that I hadn't even updated it since I merged the anime characters into the animation pages, oops). You have to remember that when I created this page I did so on my own without any assistance, so I kind of only did what I felt was right at the time... Anyway, I'd be fine with moving them to the "See also" section, as long as all those lists are moved there. Historyday01 (talk) 20:52, 30 July 2024 (UTC)

It doesn't matter much to me, as long as it's consistent. Nosferattus (talk) 23:33, 30 July 2024 (UTC)

I can agree with that. Historyday01 (talk) 02:27, 31 July 2024 (UTC)

Yivo

Yivo is a planet-sized alien whose reproductive organs are millions of tentacles. The show makes a joke about Yivo using neopronouns since it doesn't have a gender. Yivo clearly fails our inclusion criteria as it belongs to a genderless species or class of beings. Nosferattus (talk) 19:37, 30 July 2024 (UTC)

In my view, the sources speak for themselves. Regardless, I do think we need evidence that the show is making a joke about Yivo using neopronouns. Like, if there is director's commentary or something, since the DVD reportedly includes a "Meet Yivo!" featurette with David Cross (the person who voiced Yivo). As it so happens, I got a recent copy of the film (and bought all of the Futurama episodes apart from the newest season), but I'm hoping there is something else somewhere, because the Futurama: The Beast with a Billion Backs page is of no help here: the only main mention of Yivo on that page is the plot section which, like most plot sections on this site, has... no sources. The discussion topic Should we use "Schle" when refering to Yivo? is not much help either... And I don't think Infosphere is reliable source either... Historyday01 (talk) 20:59, 30 July 2024 (UTC)

If you've seen the episode, it is obviously a joke. This is especially evident from the neo-pronouns given, which are not neo-pronouns used by non-binary people, but suspiciously close to a shm-reduplication. "Schle" was close enough for the comedic effect, but not blatantly derisive like "schme" would have been. Regardless, we don't need a source explaining the joke, as the inclusion criteria is clear. The whole reason we have those inclusion criteria is to keep this list at least somewhat focused on the LGBT concept of non-binary gender identity rather than being a list of talking toasters, cars, robots, and aliens. Nosferattus (talk) 23:31, 30 July 2024 (UTC)

I understand what you are saying, but with the existing reliable sources, we are going to need a source to prove otherwise. If not, I'd fear we are going into WP:OR territory on this. I didn't find anything useful on the badly sourced Religion in Futurama page, but this SYFY review (of the fourth part of the film) doesn't include anything about Yivo's gender being anything other than male (and uses he/him/his pronouns for Yivo), while another SYFY review of the third part of the film adds: "Yivo extrudes shlimself (shlee is without gender, though shlee sounds distinctly male, so for narrative purposes we'll stick with "him" from now on)." The same is stated on page 40 of M. J. Buckman's book "Bent Is Not Broken" (it's by an indie publisher). I found some other mentions of Yivo in books here and here, but NO mention of gender in either page, while Pop Matters uses he/him/his pronouns for Yivo in a review of the film. The same is the case in the review by Common Sense Media. Due to these difference in sourcing, I don't think its enough to say it should be removed, which was why I was mentioning getting something from the movie staff (or those from the show more broadly) on Yivo, if at all possible. And since we both have different viewpoints on this, I don't think there is a consensus at this point for removal. Historyday01 (talk) 02:50, 31 July 2024 (UTC)

Adding Venture and Clove

As the title says. Never edited Wikipedia myself, but I wanted to suggest the addition of Venture / Sloane Cameron from Overwatch 2 as well as Clove from Valorant due to them both being introduced as each of the game's first NB characters. Froyodoyo (talk) 00:12, 20 August 2024 (UTC)

Why was the Pyro removed from this list?

I added the Pyro to this a while ago (on an account I dont have access to currently) and I was wondering what the reason for their removal was. Babzai (talk) 00:29, 27 February 2026 (UTC)

Probably because the entry didn't have reliable sources. I try to keep a tab on that when it comes to this page, just to make sure the best possible sources are used because some people tend to add characters and either add no sources, or very weak sources.

Please add Rag Doll (Peter Merkel Jr.) from DC

Rag Doll is implied to be non-binary; he once took on a role and costume similar to Robin within the Secret Six, calling himself the "Boy/Girl Wonder". In post-Rebirth continuity, the character is explicitly identified as non-binary, with Bane referring to them with they/them pronouns. ~2026-22349-78 (talk) 23:41, 10 April 2026 (UTC)

That sounds great. You note that the character is "explicitly identified as non-binary." Can you provide a reliable source for that? If there is one, then it can have an entry. Historyday01 (talk) 00:21, 11 April 2026 (UTC)

Keeping Mizuki

@Burstfoot I understand that she/her and they/them are used in the English localisation, and I agree that is confusing, but I believe there is only one instance where Kanade, who didn't know Mizuki's secret at the time, refers to Mizuki with she/her in an early area conversation, whereas Rui, Mizuki's close friend and someone who knows Mizuki's secret, has consistently only referred to Mizuki with they/them throughout the game whenever pronouns are used. He uses it in Ena5 episode 4, which is a significant decision for the localisation team to make when the episode is about the aftermath of Mizuki's outing. Additionally, someone from SEGA staff officially posted a statement on Discord saying that Mizuki's pronouns are officially they/them. As someone who speaks Japanese, I can also confirm that all pronouns are avoided in the original Japanese, but I want to point out that that is definitely very intentional. In Ena5 episode 4, again, Rui mentions Tsukasa (implied), and refers to him with 彼 (kare) in Japanese (timestamp 19:45), which just means he. Rui uses 彼 (kare, meaning he) and 彼女 (kanojo, meaning she) to refer to other people all the time (timestamp 9:35), and yet always avoids using any pronouns for Mizuki, clearly indicating that is an intentional choice. Mizuki's themes are also very genderqueer, since their whole theme is just "I just want to be myself", and their use of ボク (boku) in katakana which makes it stand out, and they never identify with any specific gender in neither English nor Japanese. Though genderqueer themes does not make a character canonically confirmed to be genderqueer, I think it strengthens the point about their transfemininity, and also means that genderqueer and NB interpretations are very much on the table, whereas cis ones are not. I agree that Mizuki's gender is not confirmed, but given all the evidence it is very clear they are transfem and use they/them pronouns (in English, and in Japanese they don't use pronouns which is not due to it being Japanese but rather due to it being Mizuki). To be clear, I don't mean to say that Mizuki cannot be a trans women, because to me it appears that they are canonically transfem and use they/them pronouns, and trans women can be included under that umbrella. Because of this, I think they deserve to remain on this list, just as much as a character like Kris Dreemurr does, though at best I can understand a change from 'genderqueer' to 'unstated'. Thank you. ~2026-34264-60 (talk) 04:31, 11 June 2026 (UTC)

Bare minimum, genderqueer needs to be removed, there is no basis for Mizuki specifically and canonically identifying as genderqueer besides personal interpretation - I can understand the reading but don’t believe it merits being on this page.

The problem with having Mizuki on this list is that all the characters, who don’t know about Mizuki being assigned male at birth (besides Rui, as you mentioned) refer to Mizuki as they/them in the English translation upon sight, despite the fact that Mizuki is completely closed off about the fact they were assigned male at birth, to the point that they completely break down when Ena finds out about it in Mizu5. To believe that because Mizuki is referred to with they/them by other people (Including Nightcord, who are also completely and canonically unaware of them being assigned male at birth) would require to believe that Mizuki is openly and proudly off-screen mentioned being non-binary and has informed everyone of their preferred pronouns, but simultaneously repulsed by the idea that someone knows they were assigned male at birth. In Mizu5, Ena is suprised by the revelation that Mizuki was assigned male at birth and their secret was related to their gender identity, indicating by all methods that they were acting as if they were a cis girl to the rest of Nightcord (something that fits in line with Mizuki’s presentation being completely feminine all the time besides their usage of Boku, which could just be keeping a habit from before they transitioned or just a small example of gender nonconformity). It seems unlikely to believe that Mizuki is openly non-binary while never wanting anyone to know their assigned sex, as people around her would guess that they have to have been assigned either male or female at birth.

The discord screenshot is 4 years old at this point and before Mizu5 which made the fact that Mizuki hides their assigned sex at birth undeniably clear, and can equally be explained as a style guide (Officially, Mizuki’s pronouns are they/them, not ‘Mizuki Identifies with They/them’) - it seems more likely to me this was a guideline that was a way to match the Japanese text’s use of no gendered pronouns at all for stuff like promotional material that needs to refer to Mizuki (“their banner is about to release”, etc.) Mizuki’s gender identity was a hook that the game purposefully kept ambiguous leading up to Mizu5 and Ena5 to sow intrigue about Mizuki’s character, and it’s just staying in line with a lack of pronouns being used to continue that in the Japanese text.

Rui’s usage of no gendered pronouns for Mizuki does not confirm that they identify as non-binary, (though it does indicate they probably don’t identify as a boy) It, just like the rest of a lack of gendered pronouns for Mizuki indicates that Mizuki’s preferred gender identity has been purposefully left ambiguous on the part of the writers.

I do personally interpret Mizuki’s story as a trans woman who’s identity has been closed off by degendering and censorship in an effort to avoid controversy among both the JP and EN playerbase. She uses the same body type as the girls in the game, the files refer to her as JK (joshikousei) when shes in middle school despite presenting much more masculine than she does in the present, and her demeanor is unabashedly feminine and cutesy constantly. I understand that non-binary people can act as masculine or feminine as they choose, but given Mizuki’s closed-offedness about her sex at birth (non-binary people can be uncomfortable with their sex at birth but can’t be stealth by virtue of being non-binary, none of Mizuki’s closest friends in Nightcord were aware at all there was anything unique with her gender identity) it seems to indicate she was presenting female online with her friends in Nightcord, and indicates she wants them to treat her the same after knowing.

However, I think my personal reading is a moot point - Mizuki never says ‘I am non-binary’ or ‘I am a trans woman’ or anything that indicates her actual personal relationship to gender, and the only mention that is definitive is a non-public discord post from the translation team, rather than the text itself or any of the games original writers. I wouldn’t put her on a Wikipedia page for trans female characters either - I simply don’t think she meets the standards of this page.

There simply isn’t enough solid evidence to specifically identify her as non-binary - if she was, I think someone on the JP staff or in-universe would have said it by now, after “Mizuki is Mizuki”. Burstfoot (talk) 16:03, 12 June 2026 (UTC)

I totally agree with you on this. The sources raised are weak and not reliable enough to add Mizuki to this page, the List of fictional transgender characters page, or the List of video games with LGBTQ characters page. People can certainly interpret characters like Mizuki as trans or genderqueer, but this page is only for entries where it is verified that characters are non-binary. Just because someone has a queer headcanon, does not mean it should be added to this page. In solidarity - Historyday01 (talk) 18:52, 12 June 2026 (UTC)

I agree that Mizuki's gender is ambiguous, that they are not canonically confirmed to be nonbinary or a trans woman. I agree that the decision to gender Mizuki with they/them by characters who shouldn't know their gender in the English localisation is questionable because they would have no reason to use they/them pronouns, however this is likely due to not wanting to misgender Mizuki, and also due to not wanting to confuse fans of the game. It's worth considering though that the vast majority of the time, pronouns aren't used for Mizuki.

Sorry I don't have a screenshot I can link for this Discord message, but if you have the ability to join the official EN Discord of Colorful stage you can search and find it. The same person I mentioned before, Saccharin, said this "I feel like fans should respect Mizuki's current storyline and be more understanding about why certain pronouns are being used. Officially they/them though can confirm." This is similar to the sentiment of the other statement, but putting the two together it seems to suggest to me that fans were getting confused about pronouns and despite the story making more sense if characters outside of Rui (as in, characters who don't know Mizuki's gender) used she/her since Mizuki appears to be a girl, they decided against that. Given pronouns are avoided most of the time, I think this makes sense.

But anyway I do think that part of the argument is subjective, doesn't really prove anything, and is therefore a moot point. But I don't think we can dismiss that statement of Mizuki's official pronouns as just being an old guideline when it is something that has held true up until the current moment of the game. As I mentioned before Rui, who notably does know Mizukis gender, refers to them with they/them in Ena5, a much more recent event. Furthermore, Mizuki is always referred to with they/them pronouns in their promotional posts. (I should have mentioned this before, It's much more definitive proof but I forgot to mention it - sorry about that). They use of they/them pronouns is clearly intentional, purposeful, and not a mistake.

Let me emphasise that the use of they/them pronouns matches the gendering of Mizuki in the Japanese. The Japanese avoids gendered pronouns for Mizuki, but that isn't purely because the Japanese allows for that grammatically, it's an intentional choice. Apart from the in-game avoidance of pronouns from Rui which I already mentioned (the 彼 kare and 彼女 kanojo stuff), this also holds true in interviews with the illustrators and developers too. You might know of how Nightcord is referred to with 彼女たち (kanojotachi, coming from 彼女 (girl/she) + たち which makes it plural, meaning they but usually used for groups of women) in the Ena5 Illustrator interview. It is false that this means Mizuki is a girl because it's not true that 彼女たち is only used to refer to girls, it's just not conventional to do so. There are multiple of these sorts of interviews, and Nightcord is only ever referred to with 彼女たち. The use of only 彼女たち is a deliberate choice, because for mixed groups such as Vivid Bad Squad, both 彼女たち and 彼ら (karera, meaning they but the male equivalent, coming from 彼 (he) + ら which also makes it plural, but also conventionally used for mixed groups) are used interchangeably. The developers are actively challenging gender norms by doing this, because conventionally only 彼ら is used for mixed gender groups. However notably, in the Ena5, Ena and Kanade are also individually referred to as 彼女 (as in she), but Mizuki is not referred to with any pronouns individually.

Addressing your personal interpretation of Mizuki as a trans woman, I know of all of those points, and I think trans woman interpretations are valid. To add to that even, Mizuki's middle-school middle, even when they presented masculine, is labelled in a similar way, grouped with the girls with the name JC (女子中学生 joshichuugakusei). This is the only instance though where Mizuki is individually gendered as a woman - in the code, when the gender binary cannot be avoided. Other times when they must be put into the gender binary, they are grouped with the girls (like how they share outfits with the other girls), but they are almost never individually categorised as a woman. And yet despite this, we know they are canonically of the male sex as confirmed in Mizu5 (timestamp 1:02:00) - but they are never categorised with the men, which I think leaves out cis interpretations. Furthermore, Mizuki being grouped with the girls, along with the fact the developers are actively challenging gender roles as stated above, and the fact that the game has multiple songs with trans themes, such as Villain and Telecaster B Boy, highly suggests to me that this deliberate choice to not gender Mizuki is not due to censorship, as the developers are clearly supportive of trans people. It also wouldn't make sense for them to censor themselves due to fear or being banned because there would be little to no risk of being banned in Japan, and external censorship isn't an issue either as there are many other canonically confirmed trans characters in Japanese media.

But the only important part is that Mizuki's pronouns are canonically they/them, they are canonically of the male biological sex, and their gender is unknown. Like I said previously, I understand removing the genderqueer label because that can possible suggest that Mizuki's gender is defined, or canonically confirmed, when it is not. However, I do not think it would be fair to remove them from this list because there are many other characters on this list who have unconfirmed or unknown genders but are included anyway, like Kris Dreemurr, Hange Zoe, and Crona. All of these characters including Mizuki are referred to gender neutrally in their source material or by they/them in English, and have unconfirmed genders. Take Hange, the author stated the translation team should avoid gendered pronouns, that Hange's gender should be unconfirmed, and left open to interpretation. The only difference between these characters and Mizuki is the fact that Mizuki presents feminine, whereas the others present androgynously. I do not think these characters should be removed, removing them would be a great disservice to non-binary and trans representation. If Mizuki was cis or had the potential to be cis then their gender wouldn't be unknown - that is why Kris and the others are and should be included after all. I think that Mizuki's label at the very least should be changed to unknown/ambiguous/unstated, and they should remain on this list. They have that right just as much as Kris does. ~2026-34264-60 (talk) 10:55, 13 June 2026 (UTC)

I agree that officially, Mizuki’s gender is unconfirmed, as we both agree on. I think overall, the usage of they/them to refer to Mizuki is an example of degendering, wherein gender neutral pronouns are used or pronouns are avoided not to refer to a non-binary identity, but to suppress a controversial or unwanted gender identity (in this case, Mizuki being a trans woman). Because of this practice, which is frequently used to censor the identities of trans people, I think Mizuki very likely falls under being affected by it, given how her story makes the most sense if she was a trans woman who was hiding her sex at birth, given her horror at her sex at birth being discovered by Ena in Mizu5. (again, non-binary people cannot logically be stealth or hide that they have transitioned in the way Mizuki is shown to have from Ena.)

Even if it wouldn’t get the game banned, there are plenty of reasons to hide Mizuki’s gender identity, especially in a gacha game which relies on people being attached to characters and avoiding controversy to make money. It’s very clear that ambiguously gendered characters are far more common in Japanese media than explicit transgender characters, and hiding Mizuki’s identity falls in line with dozens of cross-dressing, gender ambiguous characters in anime, manga and Japanese video games. SEGA’s lack of comment on Mizuki’s identity and usage of gender neutral language could very simply be more degendering.

Either way, I really don’t think that we can point to other characters on the list to justify Mizuki being on it. I agree that those characters you provided are non-binary, but them being on the list despite no clear confirmation of their gender identity violates one of the guidelines of the page: “Characters are considered non-binary when either a reliable source identifies them as such, or it is confirmed explicitly by the character's creator(s)”. I’m not familiar with those characters enough to make an argument for if a reliable source has identified them as non-binary, but in Mizuki’s case a discord screenshot/chat-log that requires an account to view confirming the usage of they/them pronouns only on the localization does not qualify as a reliable source, in my opinion. I think this page should only serve for characters that are confirmed to identify as non-binary, and if Kris and others don’t meet those guidelines, they shouldn’t be include either. Burstfoot (talk) 15:39, 13 June 2026 (UTC)

(In response to other discussion on the talk page, I want to clarify that my own belief that Mizuki’s story makes the most sense if they identify as a trans woman is completely irrelevant to the fact that they don’t belong on this page, I only bring up my reasons for believing it and the context for why the game and creators may avoid stating it outright to show that there is ambiguity between it and Mizuki identifying as a non-binary person. The important factor is that no canonical source has stated the usage of they/them is to refer to non-binary identify rather than ambiguous gendering; and that I believe characters with ambiguous gendering shouldn’t belong on this page, including the examples listed above by the previous editor) Burstfoot (talk) 16:00, 13 June 2026 (UTC)

I understand this and appreciate your desire to remain neutral. I just want to point out that Mizuki, in this case, is a prime example of how vague or implied genderqueerness is asserted as fact without sufficient authoritative sources simply because the character isn't explicitly stated as cis. The fact that a character's gender is intentionally hidden or intentionally stated as unknown doesn't make them outright genderqueer, as androgyny and non-adherence to gender norms/stereotypes don't necessarily imply a specific identity. Especially in Japanese media in 2026. At least when it doesn't turn into cases like Hibari-kun, where the Western localization rejects part of the original author's intentions for a variety of reasons. So if you were asking me, I would remove all of those numerous examples from the article where a character's gender is simply hidden or ambiguous without objectively developing the theme within the queergender theme.

Note: I posted about this discussion on WP:LGBTQ+, WikiProject Video games' Sega Task Force, WP:PRIDE, WT:CHAR, WP:WPLIST, and WT:VGCHAR this morning. Also of interest may be a discussion at Talk:Hatsune Miku: Colorful Stage!#Mizuki's gender. It would be deeply appreciated that the users who commented in that discussion, particularly @Solaire the knight and @Jalen Barks, share their views here, as I am at a bit of a loss at what do here without further discussion.In solidarity - Historyday01 (talk) 14:44, 13 June 2026 (UTC)

I'm here via the notice at WT:LGBTQ+. I am not personally familiar with this series but in reading the discussion above, the assertion that Mizuki is non-binary or genderqueer is WP:OR and WP:SYNTH. There is a lack of independent, reliable secondary sources consistently using either term for the character and official statements are vague or inconsistent. This doesn't mean the interpretation is incorrect or unreasonable, but I'm not seeing enough support to include Mizuki on this list. —Myceteae‍🌈 (talk) 14:57, 13 June 2026 (UTC)

Yeah. This is largely based on fan headcanons that stubbornly ignore the original status quo in their desire to assign a character to one label or another, even when the authors almost directly imply that the character's identity is intentionally hidden or blurred for the sake of narrative. In extreme cases, this is even promoted by people who are openly aware that the character has no canonical identity, as you can see in the discussions about it on DVNDB. Solaire the knight (talk) 15:46, 13 June 2026 (UTC)

Yeah that was my thinking too. And unlike some other pages, this one has some specific requirements for inclusion / inclusion criteria which says (bolding is my emphasis):

Characters can be added to their list if either the work they appear in is notable (per WP:GNG), the character themselves is notable, or if the character's gender has been covered by multiple reliable sources. If none of these criteria apply, a character should be excluded from the list....Characters are considered non-binary when either a reliable source identifies them as such, or it is confirmed explicitly by the character's creator(s)...A character is eligible for this list if the character or work they appear in is notable, specifically if the character is a main or recurring character.

In solidarity - Historyday01 (talk) 16:44, 13 June 2026 (UTC)

Well there you have it. Per WP:SELCRIT, each standalone list can define its own inclusion criteria. Obviously, a list's criteria cannot otherwise violate Wikipedia's policies and guidelines, so Mizuki is problematic either way, but it's clear that local consensus has also defined criteria that Mizuki does not meet. —Myceteae‍🌈 (talk) 17:22, 13 June 2026 (UTC)

As far as I remember, the main problem is that the character was never explicitly stated as non-binary or having an implied non-binary identity. Their identity is simply intentionally kept vague and hidden to reflect the complexity of their current status. This, of course, doesn't make them canonically trans women according to the very persistently promoted fan theory just because one of the events depicts them as biological males who have adopted (external) female representation, but still. That is, as you can see, we are talking more about an intentionally unknown identity, rather than a full-fledged canonical or implied nonbinary identity.
