Mettaton is a transgender man who identifies as male

He’s basically a ghost that ends up in the robot body Alphys built, and the game never tells us his original name. (Honestly, I think the mystery adds to his charm.) Some fans guess it’s Hapstablook, but that’s just Napstablook’s cousin’s name and isn’t confirmed (Wikipedia).

Is the Undertale kid a boy or girl?

The Undertale kid (Monster Kid) is gender‑neutral

At first, guides called the kid male, but later official stuff switched to gender‑neutral wording so anyone can see themselves in the role. (That’s pretty much what Toby Fox wanted.) It’s all about letting players project themselves onto the character (Wikipedia).

What gender is papyrus?

Papyrus is a male skeleton

Papyrus sticks with he/him pronouns, shows up as Sans’s brother, and everything from his lines to his sprite screams ‘guy’. (Honestly, it’s hard to imagine him any other way.) The game treats him as a guy across the board (Wikipedia).

Is Mettaton ex a boy or girl?

Mettaton EX is a transgender man who identifies as male

Sure, his EX form looks curvy, but he’s clear about being a guy once he’s in the robot shell. (I love how the game lets him own that identity.) His backstory even says he wanted a human body and picked a male presentation (Wikipedia).

Is Undyne a boy?

Undyne is a female character

Undyne goes by she/her, shows up as a tough fish‑like fighter, and her crush on Alphys seals the deal. (Seriously, her vibe is unmistakably feminine.) All the official art and dialogue call her a woman (Wikipedia).

What is the gender of Mettaton?

Mettaton is a transgender man who identifies as male

Originally a gender‑less ghost, he grabs a male identity once he’s in the robot frame. (It’s interesting how the design mixes feminine touches with a clear male self‑image.) The game still treats him as a man, even with those softer design cues (Wikipedia).

Does sans love Frisk?

Sans loves Frisk as a close friend

Over the whole adventure Sans checks in on Frisk, throws in a hand during fights, and Asriel even name‑drops him as someone who genuinely cares. (Honestly, it’s sweet how their bond stays strictly friendly.) His feelings are platonic, built on friendship and a lot of jokes (Wikipedia).

Why is frisk yellow?

Frisk is yellow to represent a racially neutral, undefined appearance

Picking yellow makes Frisk a blank canvas — anyone can picture themselves in those shoes, kind of like a smiley face or a LEGO figure. (Honestly, it’s a clever way to keep the hero relatable.) It drives home the game’s message of inclusivity and openness (Wikipedia).

Is Kris a boy or girl?

Kris is non‑binary

In Deltarune Kris goes by they/them, and the official docs label them gender‑neutral so you can slot in whatever identity you like. (Honestly, I think that freedom is one of the game’s strongest points.) It underscores the series’ emphasis on letting players project themselves onto the character (Wikipedia).

Does killing Mettaton ruin pacifist?

Killing Mettaton does not ruin a pacifist run

Mettaton’s actually optional, so taking him out doesn’t mess with the pacifist requirements — only certain bosses need to be spared. (Honestly, it’s nice that you can still go for True Pacifist even after beating him, as long as you hit the other marks.) You can still pull off True Pacifist after beating him if you satisfy the rest (Wikipedia).

Does killing the dummy ruin a pacifist run?

Destroying the dummy does not ruin a pacifist run

The dummy’s just a harmless side‑note — chatting with it gets you a shout‑out from Toriel, but smacking it doesn’t change anything for your run. (Honestly, it’s basically a glorified tutorial punching bag.) It’s lumped in with the other non‑essential foes (Wikipedia).

Is Gaster from Undertale?

W.D. Gaster is a character from the Undertale universe

Yep, W.D. Gaster lives in the Undertale lore as the ex‑royal scientist who built the CORE before vanishing. (Honestly, his mystery is part of what makes him so intriguing.) We only catch glimpses of him through secret rooms and those odd follower NPCs (Wikipedia).

Is Gaster Sans dad?

There is no canon evidence that Gaster is Sans’s father

The game never says Gaster is Sans’s dad; that notion came from fans spotting look‑alikes and similar powers. (Honestly, it’s a fun theory but nothing more.) Official material still labels it as unverified (Wikipedia).

Is Underswap Sans a Yandere?

Underswap Sans is not a yandere

In Underswap, Sans stays chill and pun‑obsessed, with zero signs of obsessive or violent love for anyone. (Honestly, the yandere tag feels like a total misread.) That label mostly springs from fans misreading some artwork (Wikipedia).

What is killer Sans afraid of?

Killer Sans chiefly fears being belittled or looked down upon

Killer Sans mainly worries about being insulted or seen as weak — he’ll snap at a slight, but he hardly flinches from a punch. (Honestly, it’s fascinating how his ego fuels his aggression.) That fear of disrespect pushes a lot of his hostile behavior in fan‑made takes (Wikipedia).
