Frans fankids in the big 2025🙄

Made my frans fankids! ...I think... I have an unhealthy obsession with creating fankids (first two like even more like oc's bcs adopted but.... here we are)

About them:

━━━━━━━━━━━━━━━━━━━━━

OBRI

Species: Monster

Age : 16-18

About her: That one girl :"did you know that ya' boyfriend is cheating on u?!!" Usually just a cool chill girl, but if you fuck her up, she can kick you with her heels. loves fashionable clothes and take selfies on Instagram or smth else like that

Hobbies: doing that one aesthetic selfies with girly quotes in stories and she also likes fashion? Maybe

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CURI (who the fuck wrote this text)

Species: Human

soul: integrity

Age: 11-13

About her: A dumb nerd. she constantly corrects everyone in conversations and for this she gets beaten behind garages. She thinks she's a Megamind and the future Einstein. It's hard for her to make friends because of her nerdness sometimes

Hobbies: being a member of a thousand clubs like "Fraction fans " in which she is the only member, Also plays weird tabletop games

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CARBEL

Species : ??? (Lab victim😍)

Age : 5-6

About him: He's a weird dude, but so far ppl attribute this to his age. He always appears out of nowhere at random moment of time, does some shit, and leaves. He's a funny guy, but his sisters a little bit scared of him.

Hobbies: God knows. likes hanging out with some monsters/humans in the kindergarten/school. The only one who agrees to play In weird tabletop games with Curie

So I've been doing some redraws of drawings I've done and never finished or just want to redraw lately so here's one ^^. I also plan to redesign my ship kids and update their backstories from when they are kids to adults or however old they get.

Original sketch down here ⬇️⬇️

Onyx- Me

Candy- @dreamys-mess

Momo- @asher-guaxinim

my main UT fankids growing up ✨ this layout might make their main designs (oldest ages) seem older than they really are, but they're actually all under 10 years old and still Very Baby™

these were just supposed to be simple doodles but I realised I currently don't have any descriptions of these three up anywhere, so until I make their proper references I'll put some basic info about them under the cut!

Summer (she/they)

not quite as fierce as Undyne or as nerd-rambly as Alphys, but definitely inherited both their mothers' enthusiasm levels. can be a little bossy sometimes, but they're great at encouraging others.

loves being active in any form, be it sports, dancing or fighting.

always grossed out by her mothers' public displays of affection, but otherwise loves outdoor activities with Mumdyne and playing video games with Mamalphys.

can summon electric spears and use orange attacks, both of which they use to keep people moving with them.

was accidentally given a spear to chew on as a baby by a sleep-deprived Mumdyne a whole One time, and from then on somehow always managed to keep finding more spears to chew.

Autumn (he/him)

seems like a clumsy bookworm but he can easily keep up with his sibling's activities, even if the way he tries to read while jogging has mixed results.

particularly loves reading fairytale and fantasy stories, as well as learning about monster history and the Underground.

thinks it's cute that his mothers are so in love like the couples in his favourite storybooks, and enjoys anime with his family despite preferring to read manga.

can use green soul mode and electric magic, though he mostly uses the latter to light up the dark rather than for attacks.

was very shy as a baby/toddler, being nervous around strangers and happiest being cuddled to sleep by family.

Neue (she/her)

named after and speaks in the font Comic Neue, which has been described by some articles as "Comic Sans' child":

Sans' parenting resulted in her taking after Papyrus more than either of her parents, but Toriel's influence at least lowered the volume. kind and shares her parents' awful sense of humour, but can be prone to causing harmless mischief.

adores Halloween and spooky aesthetics, and can make herself look creepy just as easily as her dad.

wears a headband with fake horns until her real horns grow in, which has been part of her design since 2017 but the coincidence of Kris doing the exact same thing in Deltarune made me very happy 💜

the skeleton onesie she wore as a baby was Toriel's idea :'>

UT Fankidtember Day 1: First meeting

https://archiveofourown.org/works/41408973

Rating: General

The Dreemurr children visit their mom in the hospital, worried that something terrible is going to happen to her.

Instead, they meet someone very special for the first time.

-+-

This is just a small oneshot about my Soriel kid and the first time kids meet her. Not sure if I’ll do every day, but I’ll try!

I wrote this for @atdffpetra‘s challenge, go take a look for yourself!

Also, I have a sideblog dedicated to all the kids that’ll eventually pop up, @askutfankids. Make sure to send in an ask if you’re curious! I don’t think I’ll have time to draw anything for it besides refs for new kids but I will answer any and all asks!

List/Description of UT au fankids I have.

(And need to draw hchdhf)

-------

Bud(Helvetica)

(STORY PURPOSES ONLY I DO N O T SHIP THIS) Parents-underfell sans and Underfell papyrus

Age-18

Male

Was heavily abused and basicly just treated like a slave/errand boy. Wears long clothing usually to hide all the bone scars and cracks. He was rescued from his world by nebula and buds now boyfreind, pendulum. He goes by Bud because his real name reminds him too much of his old life. Acts tough and feisty but behind doors he's actually very gentle and panicky. He worries about becoming like his parents and constantly needs reassuring from nebula and pendy

Daydream

Parents-Underswap Sans and nightmare

Age-12

Male

Daydream was an accident thanks to blue spending time trapped in nightmare. Blue was helping dream chase nightmare off when nightmare caught him and captured him. Eventually dream freed him and nightmare left underswap. Weeks later blue started coughing and throwing up a black goop. After ten minutes it stopped and just when blue and his brother started to try and clean up, they heard a soft baby crying. Clearing away a small pile, the brothers found a half skeleton half goop baby bones. Blue insisted on keeping the baby and dotted on them, naming them daydream. Daydream nowadays is a depressed lonely child as many of the other monster children bully him. He wears a poncho and abandons to cover his goop parts (was helped with his birth story by @jumpybox )

Atlantica

Parents-Classic Alphys and Classic Undyne.

Age-24

Came to the sanctuary with her mothers on accident afteran invention accident. She stayed on as the sanctuary's handywoman. She has an affinity for wrenches and is very temperamental and strong. Also is very smart bls don't mess with this dinofish woman she will murder you

Marble

Parents-ink x fresh

Age-13

Male

Marble is an orphan that found his way to the sanctuary after his parents were killed by an odd being. He deeply misses his family and has a little sister he was separated from. To hide his sorrow, he acts like an odd combo of his fathers. He can summon balls of ink that can harden. He has a rainbow cat plush that's his sister's stuffed under his bed.

(More to come!)
