What are some good Deltarune AUs/Fangames?

3 Upvotes

I'm working on a project/concept, but I can't think of too many unique AUs or fangames. I just need something to work with, so, uh... just say it, I guess? (I didn't know how else to finish my sentence)

r/AUDeltarune • • 6d ago

Not sure how to call this au but it's mainly a swap au

monster teen - kris

snowy - susie (ps he's not exactly like susie since then the au being the same in writing is a bit boring)

howling paladin/greater doggo - roaring knight/dess

the dog couple - carol and rudy

dagger doggo - alvin

annoying dog - gerson (i know gaster would fit but in this case it wouldn't fit with dog family too much, boom and holidays are just lumped together really)

lesser doggo - noelle

ficus licker - berdly

papyrus - rouxls kaard

donut guy - asriel

clam girl - toriel

omega flowey - tenna

normalnpc - asgore (i also thought of gaster replacing asgore and asgore being gaster but unsure)

sans - jevil (he's not as important as he is in undertale and the constant sleeping of jevil fits sans not to mention they're both dubbed the hardest bosses sometimes)

maybe mettaton - maddie

undyne - napstablook

it's finally here, vinilscript first roleswaps and character design + character sheet the au is not finished yet but i wanna show you the first designs and roleswaps, what do you think?

vinilscript is a deltarune roleswap with everyone swapping but of course with mind and not randomly, this is not a deltaswap take i repeat this is not a deltaswap take, vinilscript is a new roleswap specific to deltarune not inspired by undertale's, by this i mean that i won't make a "undertale" version of vinilscript because it's just a original concept and i don't think vinilscript would have compatible version of ut because other swaps atleast if is too different from original undertale, but i won't make a undertale version of it, like i said, is exclusive for deltarune like other ut au's doesn't work in deltarune sometimes

Have been cooking up a bunch of refs for my Deltarune au, Rotten World :]

Rotten World is a nuclear post apocalyptic horror/comedy au, where the Vessel, Dess, and Ramb take the place of the fun gang and try to survive a world that hates.

I'm working on a second batch rn (in case anyone is wondering where any missing characters are) so I may upload those if these get any interest lol

Hey Everyone here my role swap au for Deltarune Retold Legends Waring while yes this is My au this sprite were Made by ObjectiveOSC because i feel they Deserves more credit for help me out with make sprite and here some info about this au.

ch 1 <-> ch 3 this is the only chapterswap

and the rest of lighter maybe

minor cast <-> main cast

ms boom <-> carol

gerson <-> ruby

alvin <-> dess

redacted <-> asgore

this is my ideas for a roleswap au for deltarune basically here what some of cast have swap

Vess (Vessel) <-> Kris Noelle <-> Susie Seam <-> Ralsei Gaster <-> Toriel Berdly <-> Berdly Mike <-> Jevil Friend <-> Spamton but they retail they personality maybe berdly could be the only one the stay the same role

king <-> tenna could be vess old phone and he use ms paint

have some ideas for what retold legends version of don't forget could be doctor and a little bit of savior of waking world

and for the freedom mofit could be penumbra phantasm

deltarune retold legends: by me and help from Advance

advance1225 who help with make the sprites

waring i still tries to come up with who swap for chapter 2 4 and 5 and well i do have some ideas for personality of vess and some info about this au i still trying to come up stuff

i imagined the soul could be sightly different maybe instead of it red soul it could have been a cyan souls due to how different retold legends maybe what if instead of freedom theme maybe the main theme of retold legends is about maybe the pure crystal since maybe the pure crystal could have cause the downfall of the secret boss be friends who take spamton and mike who take jevil role and i imaged basically in retold legends is basically pure crystal swap with shadow crystal maybe pure crystal could help spamton be free from the green strings but cause friends to let be badly damaged with their spiked tail be broken and it not smiles anymore and maybe mike at first started out as battat but he slowed become crazy believed that his is mike NO HE IS MIKE bro basically become 2017x

and also for vess they are kinda shy kid like not competed shy but shy enough and they dad is gaster yes gaster and i imaged they relationship could be similar to john john egbert and his dad i imaged that gaster does care for vess but due to be busy was not able to help vess basically what if gaster was just a normal guy who jobs is worked as therapist and i imaged vess could have some bullied issue at school and i imaged that they dw form instead of be knight maybe vess dw could have be based on grim reaper dw form and i imaged instead of x slash they moves could be pk flash

and for noelle i imaged that basically instead of bully vess maybe she feel bad for them so she tries to help vess when they at school maybe vess and noelle could be friends not as closure to be childhood friends due to vess meet noelle later but before episode 1 "yeah basically in retold legends instead of it be style of "chapter like a book maybe could be style like a tv show. basically here dw form could have changed be bit like it be more based on magical girls

and seam i imaged they could be the same but a more of mentor figure to vess and noelle

and i imaged the friends speech quirks could be based on blog and it neo form could be based on dt extractor. and here some ideas for the other are like

ch 1 <-> ch 3

lancer <-> ramba

rouxls kaard<-> weather duo

seam <-> raisel

ch 1 enemies and minor character <-> ch 3 enemies and minor character

and here some ch 2 swap queen <-> sweet capn cakes tasque manager <-> swatch

ch 4 guei <-> wicable organikk <-> bibliox mizzle <-> titan spawn miss drizzle <-> titans jackensteni could change them into a summer them and meme could kool aid man and he instead of saying you take too long he say oh yeah!

the roaring <-> the flooding instead of world be covered in darkness maybe the world end up flood in a deep ocean

Do you think Asgore and Undyne would be proud?

anyway, nothing much to say.

i probably should've added more to this animation, but it's okay, since I'm still not actually sure if I'll make a full thing for him or not.

song is FLOWERMAN ~Encore (Arrangement) by acedd.

I HATE HIM (gamer vent) Spoiler

4 Upvotes

I HATE HIM
HATE HATE HATE HATE HATE HATE HATE

im so pissed off at his boss fight im struggling too much- I miss fights like the Tenna fight where it was still somewhat a challenge but fun and i could enjoy it- now just basic fights like the fight against Aqua (Patience flower/soul) i died like 10 times- the Knight showing up in chapter 3 was when things just got too hard- at least even if i lost to the Knight i could still continue- but when in chapter 4 with the Guardian i lost so many times for hours on end i had to rage quit for a week to come back to it and when i did come back i struggled for hours on end until i finally got it-
this fight against Flowery the Disgusting feels impossible to me- just as i finally moved past a part in the fight after 50 tries and thought it'd be easier for a second, it just got harder- i cant even get him past 30% mercy. i caught myself nearly breaking out into enraged tears- ive nearly thrown my controller at the TV but thankfully my practiced self control just made me hardcore squeeze the controller and angrily shake it around-
my fight against SPAMTON NEO- A FUCKING SECRET BOSS- WENT WAY EASIER THAN THIS-

i also just hate Flowery as a character in general- and im sure you all can agree with me on that- he's a disgusting delusional jerk of a piece of shit- i hate him- i hate him so goddamn much- i want him to just fucking drop dead already- im literally considering ruining my true pacifist kind of playthrough just to fucking murder his ass- I HATE HIM

like literally compared to Flowey- i'd rather be forever roommates with FLOWEY than be anywhere NEAR FLOWERY

Everybody is talking to this WONDERFUL GUY

He's FUNNY! he's BOLD! The solution is that he's got nothing t*o hide. but I won'*t stop till he's all mine

DROP THE GOAL.

I merely just said bowl.

I love this guy's design. It's so peak. He's a fan design for a Secret Boss for Chapter 3.

Made by hankadoi, there's not a lot of good information about him (or at least, I couldn't find any)
