ꔠ > Roleplay Starter : The Fields

In a simulated universe, you are brought to a virtual landscape - specifically on a plain and lonely island in the middle of the vast ocean. Above are the vibrant blue skies adorned with fluffy white clouds. There in the tall grass stands a lone skeleton with strange discolored arms taking a stroll, their back turned. They were humming to themselves, mindless among the fields.

Hey Y'all! I'm making an Undertale AU RP! Everyone can claim an AU until it's full, then I'll share the discord server. If you want to be an AU that isn't on the list please let me know. Tell me which AU you want to be and I'll write your name next to it. You can only pick one.

RP Callout Post!

Howdy! I was just bored and wanting to see if anyone was down for an RP.

I consider myself at least semi-lit for the most part, and I hope that whoever wants to also is at least having their style kinda like how they would use quotations and describe actions. Not too big of a fan of stuff like this:

Oliver: *he puts his hand son his hips* Hey, what's the matter?

Honestly, if you do write like that, it's fine, I just need you be organized to where I can read it, and it doesn't look like a child wrote it.

I'm good with mainly romance and angst, although I can go pretty hard with angst and traumitzing characters. If you have an triggers, i'd like to know them. I myself don't have anyone, but I don't wanna make people uncomfy.

I mainly RP as my own OCs, since I have problems with getting out of character on some. I can do them on the side if need be, but I only really do canon characters mainly whenever I bring it up first.

I also would be down to RP Minecraft, Hazbin Hotel, Undertale, TSAMS, MHA(although only really, like, with characters outside of MHA), as well as Deltarune.

If you have any questions, just lemme know! Other, hmu if you are down!

RP Request/Info

Hello! I am currently looking to roleplay here, mainly in the Undertale and Undertale AU fandoms! Here's some information about my RP preferences & boundaries. Feel free to ask questions if there's anything else you want to know!

Preferences

Style: I prefer literate to semi-literate RP. I usually write in the 3rd person but don't mind if this isn't matched.

RP Types: Action & Romance RP. Also have a preference for OC x Canon RP but am fine with other kinds

Favorite AUs & Characters: Papyrus & his AUs, Horrortale, Dreamtale (+ AUs of Dreamtale), Xtale, any of the "Bad Sanses" including Error

Frequency: I try to reply as often as I can, but I don't mind if my rp partners can't/don't, don't stress yourself out about responding fast enough!

Boundaries

Nothing that would break tumblr guidelines (for obvious reasons)

No romance rp involving shipping minors, including minor x minor (I don't see anything wrong with minor x minor, it just feels uncomfortable to me as an adult to be playing a minor in a romantic way)

No one line/ one sentence rp replies, please

No RP involving nsfw if you are under 18. If you want to involve nsfw content in a rp please confirm beforehand that you are an adult

In general I would prefer to RP with people close to my age, especially in the younger direction. I am fine with doing rp with someone who is, say, 17, since I am 19, but not as much so younger than that. Upwards direction I don't care very much

No rp for ships that are incestuous (Ex: Dreammare, Fontcest, etc.)

Additional Information

I have college classes Monday-Thursday, so I may not be as available those days

Information on my main OC if you are interested: https://erischaracterinfo.straw.page

ABOUT: A swapfell Sans who's worked hard to get to the top, and with an ego to match. A real nasty human killer, this Sans has a notable superiority complex and has decided he's so baddie everybody needs to get on his level, but they can't. rarely does any work now because he figures he's to good for it, he doesn't have to. has a fellswap brother who goes by dog.

Boss' voice claim is like a Sans doing his best Angel Dust impression.

RULES UNDER THE CUT

Hi im Hebby, I'm in my 30s and I have a whole ass life so I'm not around as often. I've been writing on here since around 2015,and I've seen a lot of BS and drama.

RULES: DON'T BE A JERK, DON'T USE YOUR CHARACTER AS A MOUTHPIECE, DON'T BE CONTROLLING, DON'T START DRAMA, DON'T DRAG ME INTO DRAMA. This blog is proship in that I don't care what people ship, don't harass people over fiction. If I think it's gross, I'll block it. If you think I'M gross, block me. If you think harassing others over what they write is good, don't try to write with me. Grow the hell up, it ain't cute anymore.

THIS BLOG IS 18+ FOR CONTENT, BUT ALSO BECAUSE I'M NOT COMFORTABLE WRITING WITH MINORS. IF YOU'RE FOUND TO BE LYING ABOUT YOUR AGE JUST TO WRITE WITH ME, YOU'RE GETTING REPORTED.

DON'T GODMODE MY CHARACTER. THAT MEANS DON'T TAKE CONTROL OF THEM.

This blog is meant to be run IC by Boss, but will have some f2f (in person) interaction.

I'M MOBILE BOUND SO I CAN'T TRIM!!

Anyone would like to do a bad sanses rp?

I am mostly semi lit.

I can do double rp if at least one of the rp is one of my trope.

I do really love ship and i am very open about them

I am searching for a 20+ years old partner, i do not wish to befriend a child and sorry but 18 years old are still children to me.

[poet-shimmer]

* rp rules.

fandom:

undertale + alternate universes (only)

requirements:

please be capable of proper grammar, punctuation, and multiple paragraphs (15+ lines). my ideal preferred length, for reference, is a message that reaches the sign limit of a discord message.

provide an rp example of yours so i can get an idea of your writing style. really, enjoying my partner's style matters more to me than the length. when i can really tell you're an eloquent, passionate writer.

be 18+. because of my own age, preference for a mature partner and dark themes. don't lie about that. please.

i have a bit of a 'funny' rule regarding ocs. i will only accept other canon characters (more about that below) *unless* you have an oc you'd like to pair up with swap!sans. even then, i won't accept just about any oc. thanks for understanding.

third person only.

be open to canon-divergence/headcanons. i very much enjoy hcs, and i tend to twist canon facts in favor of an interesting storyline.

*be active*. be capable of multiple answers a week at least.

communicate. i am very patient and forgiving with my partners, but if i constantly have to second guess if you're busy or bored with what's going on i might just cut ties for my own sake.

please, please, please don't let me carry the plot. someone who knows what they want in a plot and brings ideas would be so great.

tell me your triggers.

ooc chatter isn't a must per se, but it means a lot to me. it usually raises the fun and activity! dry ooc talk really affects my mood honestly.

playlists, moodboards and rambles/hcs based on the characters/plot? umm, yes please?? again, not a must, but *so* appreciated.

about the user:

call me rose!

they/them

above 18

CET timezone

10+ years of experience

can mirror replies with little effort

needs a plot

highly prefers discord as a platform

discomforts/pet peeves:

venting without permission

people who easily lose interest

triggers will be disclosed in private

yes men. please don't just say "i don't know" or "you choose" or "whatever you want!" all the time.

character information:

✅ will do:

favs

✒ ink

main!

lots of experience, lots of hcs

☀�� dream

secondary main

a bit of experience, a good bunch of hcs

🌊 swap

NOT blueberry

OC ship friendly! (only him)

🌑 nightmare

zero experience so far, but very familiar with the character and willing to try!

🗨 classic

☠ reaper

others

anybody who isn't on my 'won't do' list, really! especially if they're from classic undertale. toriel, alphys, undyne, papyrus... you name em!

❌ won't do:

any rps involving characters from...

underlust

underfell

glitchtale

x-tale

(+ any alternate universes of them. the story of underverse is not at all canon to my ideas. it's totally fine to like any of those! i just don't.)

ship information:

✅ will do:

any crack- or rareship you can think about. i'm serious. whether it's romantic or platonic (and always legal ya sickos). i wanna bring characters together most people wouldn't, discover fun dynamics!!

examples:

ink and classic

nightmare and reaper

swap and swap!napstablook

(those are still kinda tame, but you get the idea!)

popular ships are fine too! they just don't tickle my fancy as much.

❌ won't do:

romantic ships involving fresh, frisk, chara, asriel or monster kid

incest

important notes:

if you read and understood all of those, then please include this smiley [🫖] somewhere in your comment/pm.

do not comment on this post! i have a pinned message for you to interact with if interested. like it or comment and i'll contact you. (or just go ahead and contact me-)

(current) cravings:

i would give anything for a good drink (ink x dream) rp. really. so if you're an enthusiastic dream rper hmu as soon as possible, i b e g-

aside from that, i look forward to playing ink, dream or classic sans against any other possible character the most currently!

Hello! 20 year old female looking for more partners to have random fun and adventures and even OC x CC (maybe OC x OC. It’s good fun for both of us!)

I’m a pretty open minded person so I don’t mind angst (No crazy amount though please!) and Sfw/NSFW is completely fine! I love fluff, adventure, action, and I love doing random scenarios based on my multi fandom AU, Unitytale! (Check out my blogs for more info: https://at.tumblr.com/pokegalla/g8ihpgpqnjx3 and DM me for any questions. It’s ok to ask questions even during a scenario!)

Fandoms including…..

Undertale AUs

Gravity Falls

Hazbin Hotel/Helluva Boss

Deltarune

Pokémon (mostly most recent games)

Check out both my blogs to get a general idea of my writing and kind of characters I can write for including a bunch of my own characters too! My character that I usually use is a self insert so you’ll see her often. Let’s see what stories we’ll create! Let the chaos commence!!!

Undertale Multiverse RP Group Interest Check ™️

A lengthy explanation of what it would be, subject to change if there's enough interest and I encounter snags when (if) I start actually putting shit together,

18+. Adults only, both OOC and IC. - Listen, I don't care what your fictional interests may be, they're yours. But I'm the one that's going to be moderating the Discord and junk, and I'm pretty sure lolisho is against Discord ToS - it's also no bueno in my country. I don't want to deal with (the potential of) it. - I'm not going to enforce some sort of ID check but if people start suspecting you're a kid trying to infiltrate an explicitly-stated adult space, there may be exceptions. If it's found out that you're a minor with zero doubts on the matter you'll just be kicked, blocked, and warned about without preamble. - IC your character can be as much of a blubbery dramatic insufferable manchild as you want them to be, they can be immature, whiny, annoying, whatever. OOC, no. Be a mature human being. That isn't to say you can't be silly, I'm a goofy goober myself, but don't start unneeded drama, don't try to start witch hunts over stupid nothingburgers, etc, etc, yadda, yadda. On that note...

Proship-aligned persons only. Antis will not have a fun time.

The OOC portion would be on a private Discord server whilst the IC portion would be on Wire to allow for a greater separation of IC and OOC. - It would allow the socially anxious or Just Not Up For It Right Now individuals to simply not log into their IC Wire accounts if they don't want to play, without having to tell anyone trying to interact with them "not today sorry." - It would allow for a more 'immersive' experience (or such was my experience with MSN groups ran this way). - Discord would be for ooc chatter, headcanons, character info, squeeing about the blorbos, planning player-driven events or encounters or incidents that need such planning, etc. I'm thinking a channel for introductions where you can state your limits (what you're okay being approached with, what you aren't okay being approached with, etc) and the like. It would allow people who aren't into it that day to join in on IC / OOC game nights, movie nights, or whatever else someone may wish to try dragging others into.

The Wire profile(s) would largely function as your character(s) phone(s). The baseline idea is some idiot has uploaded a self-sustaining form of malware that infects phones through casual browsing and adds each infected phone to each other's friends lists with no care for where they may be in the multiverse and no way to un-add those friends. Sure, your character could just get a new phone or something, but for the sake of the group thing it just keeps happening. - IC Face-to-Face interactions can be planned over these messages or your character can just pop in on those they know or whatever. The separation should be obvious considering the next point, a - IC texting absolutely does not have to adhere to grammar, capitalization, spelling, whatever. Your character can be as shitty a typist as you want them to be / as shitty a typist as they are ICly. IC Face-to-Face, however, should be structured like the typical roleplay fare ("Hey," blorbo said, "Catch me outside, how about that."). - Mysteriously finding strangers in their phone contacts will give your character an easy way to approach characters they don't know by simply asking "who dis" or some variant thereof.

Things will happen whether your character is online or not, and these things may or may not effect your character down the line. The idea is for the roleplay portion to be a Persistent World-type of thing. One day OOC is one day IC with exceptions for AUs where time functions differently. - Things your character does may have player-driven consequences (ie. your character making an enemy of another character might make you an enemy of their friends, too; attacking them may end up with their friends coming after your character; etc).

I'm thinking initially people will be allowed three characters. - Wire allows you to use multiple accounts at one time. You can also just log into whomever you're feeling that day. - Non-established AU characters are most certainly allowed, as are OCs made for the Undertale setting. - There will only be one instance of established/popular AU characters (ie. one Fell Sans, one Ink, one bluh bluh bluh) allowed in the group roster. If it's taken, it's taken. Variants (ie. Ink Sans, Pale Ink Sans) are obviously treated as separate characters. I'll have to make a list of characters whom are taken (as well as requested) that will be available on Tumblr and whatever other sites I might utilize to advertise the group. - Wires and Discords would not, however, be publicized! If accepted you'd be invited into the Discord, and there'd be a channel where people can drop their Wires.

I won't be accepting people with blank Tumblrs in effort to avoid antis and kids trying to sneak in using throw-away accounts. If something looks sussy I may also err on the side of caution. If you don't have an age or generalized category (ie. "I'm an adult") in your bio you'll be turned away. Sorry not sorry. - The only exception will be if you have someone who can vouch for you.

Proposal to the UTMV Community to Revitalize the Fandom: On February 12, 2016, Muffet's Love Ball RP was hosted. This was a huge step for the UTMV Community. In modern times, the amount of UTMV content has started to slow down. I believe that if we do a similar event, we can create a surge in the UTMV community and bring back a lot of activity. That's why I'm proposing that we create another Love Ball-type roleplay event on February 12, 2026, the 10th anniversary of Love Ball. I don't have any of the specifics thought out or planned, but I'm willing to put in the effort to create such an experience if y'all are willing to help out and participate in it. The name is subject to change, but I'll call it "The Violet Banquet" for now. If this ends up coming to fruition, I was thinking of using a Discord Server to host, unless any of you have any better ideas. Thank you for your time. Sincerely, NegativePositive (NegPos)

Hi everyone

I would like to advertise an Undertale AU roleplay server I have created

It is a 16+ server, with organized channels for characters and character related talk, roleplay, as well as a general place to talk! While it is a roleplay focused server, you are welcome to come in and just talk and share things about your favorite characters & even your OC's if you wish.

It is welcome to OCs, and also allows more than one person to play a character- as long as they are not both playing that character within the same roleplay (unless there is good reason for more than 1 of the same character to be there), so you don't have to worry about your favorite characters being taken before you get a chance. There is also a dedicated place to find & ask for people to roleplay in DMs if you prefer.

There are dedicated channels to ask questions, get help, share ideas for changes or additions to the server, and share concerns with the moderators!

Moderator applications are also open if that is something you are interested in.

Feel free to ask questions if you have any, and I hope anyone interested enjoys the server!
