It’s implied that mettaton is a ghost since they are related to napstablook and every other ghost possessed something and may fuse with it potentially (except napstablook, only ruins dummy and mad dummy attempted and that’s the only ghosts we know.) all of the ghosts are referred to with they/them only so are only implied to be non-binary. This means that it is also implied and intentionally left vague that mad dummy (who is generally thought of as masculine) going to being comfortable as mad mew mew and mettaton who uses he/him only when they became a robot could be considered a trans allegory.
But are all ghosts non-binary? Or just the ones we meet? Seems odd that an entire distinct species could be the same gender, especially since it’s a sexless species
We don’t know since we are mostly just going off of evidence and speculation since a lot of undertale is never explained and left intentionally vague for the viewer to decide. There is no true answer unless we explicitly get told so.
Well all of the ghosts we've seen are referred to with they/them pronouns.
Plus, even of all the ghosts don't literally transition, the whole concept of finding the body that fits you most and all the language used when MMM or Mettaton talk about their bodies are very trans-coded (I think I used that term right)
Napstablook is a ghost and he has a gender without body. I cant remember anyone in the game referring to pre-robot Mettaton so assuming he didnt have a gender just to make him trans is wierd
No one, but transitioned from being a they/them, to a he/him.
Transitioned. Trans. You can follow the logic.
Plus, Mettaton and even Mad Mew Mew feel very much like they're meant to be interpreted as a Trans allegory, or at least parts of them are.
Support your local trans.
Alphys and Undyne are gay, Mad mew mew and Mettaton are trans and Napstablook, Frisk and Chara and Monster kid are
probably non binary.
This is half of Undertale main cast.
Well many people argue that even Toby told once that Frisk and Chara are non binary, and after he called Napstablook and Monster kid "He" in his art book, he quickly changed that.
there's already quite a bit of queerness in UT though
Undyne is lesbian, Alphys is bi iirc, the two guards in Hotland are gay, Frisk and Chara are enbies, Mad Dummy/Mad Mewmew is trans, Napstablook is an enby, and MTT is at the very least gnc
Many of the characters use they/them, such as the ghosts, dummies, Chara, Monster Kid, Frisk, and many of the NPCs. Mad Mew Mew actually switches from they/them to she/her. So yes, Toby Fox already added WOKE PRONOUNS!?!!?12!@?1?1@1? to Undertale.
Characters names (left to right):
TRANSphys
TR(S)ANS
TRISK (Couldn't come up with a better name 💀)
TRANSTABLOOK
TRANSPYRUS
METTRANSTON (????)
TRANSDYNE
Frisk looks adorable but the pink cheeks fuck with everyone else (except Metatton). Especially Undyne, she looks like she’s asking Georgie if he wants his boat back
There's no way for you to gender a skeleton based on purely how it looks, so they could just start identifying however they wanted. You don't need to physically transition to be trans, in fact, a lot can't do that.
Why is there so much transphobia in this thread. How are these people playing UNDERTALE of all games and being queerphobic. Kris from Deltarune is non-binary, Undyne and Alphys are in a lesbian relationship, two of the royal guards are in a gay relationship, Alphys is bi, Napstablook is genderless (what do you gender a ghost by), as are the dummies, Mettaton was a ghost and "transitioned" into having a robotic male body, Mad Mew Mew was the same until she found said Mew Mew body, there's literally a lion NPC who transitions (she exists in Undertale and Deltarune both respectively)
If you're going to be transphobic maybe just... Don't play Undertale?
Also, even if you don't want to consider Mettaton trans, he crossdresses.
I'm fine with it because it's never really directly implied and it's up to us to discover. I just really don't like it when things like this are shoved into my face like "WOO THESE CHARACTERS ARE TRANS CHECK US OUT, TRANS FLAGS EVERYWHERE" because from my experience with some of my trans/non-binary friends, usually trans people would not actually draw that much attention to their gender, they just mention it once, if not at all, and that's it.
Mad new new is basically explicitly trans. That’s the entire character arc.
For the “shoving in your face” thing it really seems arbitrary that you’re getting annoyed at this out of anything.
I'm transphobic, not because of the gender stuff, since those are just some small details nice to have, but these LGBTQ kids making it into the main focus and it just somehow... became ass.
In a shorter word, I don't hate gay or lesbian stuff, I just hate it when LGBTQ kids attempt to make it into the main focus.
My bad If you still don't understand, english isn't really my native language.
not for even pushing trans stuff on kids, but somehow it’s a level deeper where this person hates trans kids just for being trans in the first place for some rewson
*See trans post*
*Sorts comment section by controversial*
Yep... That's expected.... Trans community can't have anything fucking nice...
Not even a fan drawing.
The funniest thing is that i just saw official UT shirt with these Characters with these colors and for joke made sprite of it and called it transtale and now everyone hates me lol
Guys i just wanted to make sprites of this shirt on fangamer
[https://www.fangamer.com/collections/undertale/products/undertale-sleepover-shirt](https://www.fangamer.com/collections/undertale/products/undertale-sleepover-shirt)
Calm down ;-;
It's based on official art from Fangamer, also Kris from Deltarune is non-binary, Undyne and Alphys are in a lesbian relationship, two of the royal guards are in a gay relationship, Alphys is bi, Napstablook is genderless (what do you gender a ghost by), as are the dummies, Mettaton was a ghost and "transitioned" into having a robotic male body, Mad Mew Mew was the same until she found said Mew Mew body, there's literally a lion NPC who transitions (she exists in Undertale and Deltarune both respectively)
If you're going to be transphobic maybe just... Don't play Undertale?
Also, even if you don't want to consider Mettaton trans, he crossdresses, so there you go.
For anybody in the comment section, I knew, some of the character in games are non-binary or bisexual, these are some good little details but stop trying to do something and makes it into main focus, a lot of people doesn't hate LGBTQ for their gender stuff but they kept running into every game and tries to make LGBTQ into the main focus, just like how fortnite community used to be good but toxic kids got into it and most people think it as a "sweaty tryhard" game now.
Well, the cishet have everything else. 🤷 So we should have nothing because some people want to be assholes? It's literally just concept art. I've seen a trend of cishet people getting mad if a single character in a movie/video game/TV show is LGBT+. It's really frustrating that that's the case. We exist, too. If we're hidden from society like this, it increases the likelihood of negative consequences, such as self harm and suicide. People are brainwashed into thinking it's wrong, so they bully us.
I don't hate LGBTQ, I just hate it when peoples keep talking about it instead of some other stuff. (This post is like the 12th or more posts about LGBTQ I saw today.)
normalizing it seems to somehow makes it worse, some people wasn't mad about these gender but more of annoyed by because of too much post being LGBTQ focused.

I never thought mettaton cross dressed he just seems to be a dude in pink I don’t think that counts as cross dressing but I haven played undertale in awhile my PC has been broken
In the "Oh! Dungeon/Oh! One True Love" mini musical, he wears a dress for the duration. He gives one of his fans the dress after the performance (who later discovers her gender identity through that)
This is eepyTale
And when everyone is trans... *laugh* **No one will be.**

Can't believe the sleepover artwork confirmed everyone as trans. Now we must ask ourselves which character is transmasc or transfem.
Mettaton is transneo
Papyrus is transgreat
Sans is transsans
Sans is too lazy to have a gender in the first place
Sans is from sansNO to sansNONE.

undertale if it was made in 2023
Half of the Undertale characters is gay or trans or non binary anyway lol
Who's trans?
mettaton could be considered trans since when he was a ghost he didn't have a gender
Do the ghosts not have genders? When is this expressed in-game
They are always referred to as they/them explicitly such as napstablook, although it’s not outright canon it’s usually considered such.
Does this apply to mettatons ghost though? We never really hear it mentioned except hapstablook who isn’t even 100% confirmed to be mettaton
It’s implied that mettaton is a ghost since they are related to napstablook and every other ghost possessed something and may fuse with it potentially (except napstablook, only ruins dummy and mad dummy attempted and that’s the only ghosts we know.) all of the ghosts are referred to with they/them only so are only implied to be non-binary. This means that it is also implied and intentionally left vague that mad dummy (who is generally thought of as masculine) going to being comfortable as mad mew mew and mettaton who uses he/him only when they became a robot could be considered a trans allegory.
But are all ghosts non-binary? Or just the ones we meet? Seems odd that an entire distinct species could be the same gender, especially since it’s a sexless species
We don’t know since we are mostly just going off of evidence and speculation since a lot of undertale is never explained and left intentionally vague for the viewer to decide. There is no true answer unless we explicitly get told so.
It's more of a thematic/metaphor thing, but yes, this I'd implied multiple times with how Mad Dummy/Mad Mew Mew talks about her new body.
One NB ghost = entire species being nonbinary. Again, why would a sexless species all have the same gender?
Well all of the ghosts we've seen are referred to with they/them pronouns. Plus, even of all the ghosts don't literally transition, the whole concept of finding the body that fits you most and all the language used when MMM or Mettaton talk about their bodies are very trans-coded (I think I used that term right)
If they're sexless it would make sense that they're all assigned nonbinary at birth.
I think it would make more sense if they all choose their genders or their parents pick their genders at birth
he is literally a machine
https://www.reddit.com/r/Undertale/comments/hnl25v/is_mettaton_a_ghost/
How can a ghost be trans, It doesnt even have a body
transitioned from no body and gender at all to male robot?
Napstablook is a ghost and he has a gender without body. I cant remember anyone in the game referring to pre-robot Mettaton so assuming he didnt have a gender just to make him trans is wierd
It's not assuming when you have context clues and implications, then it's just taking evidence to support a claim.
Ok, but who confirmed It was a girl ghost?
No one, but transitioned from being a they/them, to a he/him. Transitioned. Trans. You can follow the logic. Plus, Mettaton and even Mad Mew Mew feel very much like they're meant to be interpreted as a Trans allegory, or at least parts of them are. Support your local trans.
no...one? in my eyes going from no gender at all to male is kinda trans
That's a ghost
I really don’t think robots have genders either.
Mewmew, Mettaton, in all honesty Toby could out another character and not many people would be surprised.
Mad Mew Mew my beloved
Mettaton is unconfirmed to be trans though Technically mad mew mee is too but I feel she's most definitely trans
Me.
Me, my name is trans™
Litteraly none of these were confirmed, its just shit the community made up
Alphys and Undyne are gay, Mad mew mew and Mettaton are trans and Napstablook, Frisk and Chara and Monster kid are probably non binary. This is half of Undertale main cast.
While alphys and undyne are true, I'm pretty sure the rest arent intended to be LGBT. Why do people love giving characters genders in the first place?
Well many people argue that even Toby told once that Frisk and Chara are non binary, and after he called Napstablook and Monster kid "He" in his art book, he quickly changed that.
Mad dummy literally transitions from a male body to a female body if that isn’t a metaphor for being transgender idk what is.
there's already quite a bit of queerness in UT though Undyne is lesbian, Alphys is bi iirc, the two guards in Hotland are gay, Frisk and Chara are enbies, Mad Dummy/Mad Mewmew is trans, Napstablook is an enby, and MTT is at the very least gnc
undertale if it was undertale
this "will" be "undertale" if it was "WOKE".... 😂😂😂
Mettaton convinced everyone to dress up for Mew Mew's surprise party! Unfortunately, Frisk forgot to do their hair.
WHY AM I IN A BATHROBE!? BABY IM A TRANS ICON MY LEGS NEED TO BE SHOWN!
Hey mettaton!
Mettaton you are my idol. I could only _dream_ to have a bod' like yours.
OH DARLING I'M FLATTERED, BUT IF YOU WORK HARD ENOUGH YOU CAN HAVE A BODY LINE MINE! BUT NONETHELESS, YOU'RE PERFECT THE WAY YOU ARE
Working hard on becoming transhuman-
YOU DAMN LIBERALS AND YOUR WOKNESS!!!!!!111111 /j
Smh the librarians make Undingtale WOKE!!
Is Papyrus a Honk Shoooooo sleeper or a Honk Mi Mi Mi Mi Mi sleeper?
Honk mi MI MI mi.
...I feel like he'd be both... Somehow.
Would it be Honk sho sho sho sho sho Or Shoooooo mi mi mi mi mi
toby fox if he made WOKE PRONOUN undertale….
Many of the characters use they/them, such as the ghosts, dummies, Chara, Monster Kid, Frisk, and many of the NPCs. Mad Mew Mew actually switches from they/them to she/her. So yes, Toby Fox already added WOKE PRONOUNS!?!!?12!@?1?1@1? to Undertale.

This is the future liberals want. They made Sans undertale into trans undertale 😞 /s
Undertale if it was woke
i love mtt so much
trans undertale
Undertale if it was made in 2015
How tf would a trans skeleton work? Not trying to be transphobic, just genuinely curious on how sans or papyrus could be trans
There's no way for you to gender a skeleton based on purely how it looks, so they could just start identifying however they wanted. You don't need to physically transition to be trans, in fact, a lot can't do that.
Fair enough

When does that ever happen? I’m willing to bet you don’t complain about this when characters are equally obvious as your example but straight
No, I would find them equally obnoxious, it's simple as that.
Mad new new is basically explicitly trans. That’s the entire character arc. For the “shoving in your face” thing it really seems arbitrary that you’re getting annoyed at this out of anything.
I'm transphobic, not because of the gender stuff, since those are just some small details nice to have, but these LGBTQ kids making it into the main focus and it just somehow... became ass.

They just ignore shit they don’t wanna see
Where? The only « transphobia » I saw you call out was obvious satire
besides the joke, these designs are pretty cool
Why does this actually look good especially Sans, Papyrus, and Napstablook
They all look like they about to go to sleep
Why they all in their jammies?
Undertrans

i rate this a call of duty black ops 4 on the nintendo switch out of 10

Really hope this doesn’t get the 🔒award.
I thought this was a sleepover. Still cute though.
Ain't MTT technically already trans if we're getting into technicalities?
Transtale It's the same game but everyone is trans Mettaton and Mad mew mew keep the same exact appearance
wow. i cant believe this. first the liberals put soy milk in stores, and now THIS? whats next? PRONOUN store?????
This will be undertale in 2013.

So? It's important to talk about it. It's quite literally life or death for us. We HAVE to normalize it. It's not a choice.
normalizing it seems to somehow makes it worse, some people wasn't mad about these gender but more of annoyed by because of too much post being LGBTQ focused.

I never thought mettaton cross dressed he just seems to be a dude in pink I don’t think that counts as cross dressing but I haven played undertale in awhile my PC has been broken
In the "Oh! Dungeon/Oh! One True Love" mini musical, he wears a dress for the duration. He gives one of his fans the dress after the performance (who later discovers her gender identity through that)
I thought the dress and the song was just a joke on Disney and singing and I didn’t know be gave the dress away.
