BadTrioTale

This is a Undertale AU that changed after a major event that happened a few years before Frisk fell down. The underground has some "new" monsters. This AU has all the characters from 3 different AUs team up on every boss battle and make things even more difficult for the human. Those AUs are UnderSwap and StoryShift. 
== Characters ==
UnderTale characters
StoryShift Characters
UnderSwap Characters
(i will put the information here one day but not right now because it would be very time consuming)
== Information ==
YOU ARE ALLOWED TO MAKE AUS BASED OFF THIS AS LONG AS YOU GIVE CREDIT
=== The Monsters all were teleported to the classic underground and these are the main trios ===
Flowey- UnderSwap Temmie- StoryShift Boogie
Toriel- UnderSwap Asgore- StoryShift Papyrus
Papyrus- UnderSwap Sans- StoryShift Asriel (yes i know about the bad time trio Fan game)
Undyne- UnderSwap Alphys- StoryShift Toriel
Alphys- UnderSwap Undyne- StoryShift Asgore
Mettaton- UnderSwap Napstaton- StoryShift Alphabot
Sans- UnderSwap Papyrus- StoryShift Chara (yes i know about the bad time trio Fan game)
(Potential ideas below)
This could become a game if i am able to find a team to help program.
There could be a multiplayer mode because the humans might also be in a trio or duo
There could be difficulties for how many of each trio is in a battle
== biggest changes ==
The trio of Alphys- UnderSwap Undyne- StoryShift Asgore now has a boss battle in the Genocide route of the game.
You will also battle Asgore, UnderSwap Toriel and StoryShift Sans in every route (pacifist, neutral and genocide).
If you do the Genocide run one member of each trio will survive their battle and band together to defeat you before you meet Chara, UnderSwap Frisk and StoryShift Mettaton and destroy their world. The entire flowey trio will be there too, seeing as there is no previous battle against them. (The one survivor is chosen by random)
When the other monsters came through the portals so did their 6 souls and now the barrier requires 21 souls to be broken permanently.
Depending on the survivors the final battle in the Genocide run will be different and there will be lots of outcomes for the battle.
During the neutral route, the survivors (if you killed a trio) will battle you in vengeance.
All 3 of the flowey trio monsters have an omega form that you will fight at different times. They also didnt team up so you will enter a random battle agaisnt one of them around every 20-60 minutes and there difficulty is scaled by how far you have gone. 
The save points dont heal anymore.
Also in the Papyrus- UnderSwap Sans- StoryShift Asriel fight there is a very small chance for one of them to go disbelief and when one does the others can’t this time the survivor isn’t random and the one who died to save one from the Papyrus- UnderSwap Sans StoryShift Asriel trio from the Sans-UnderSwap Papyrus- StoryShift Chara trio is random and they will be replaced by who they saved.
(some of the information is if this becomes a game and you guys/ girls are allowed to make fangames based off this and if I’m able to make this into a game I might use a few fangames but i will program most of it with other people when I learn how to mainly but if someone makes something that is almost how I want it to be then I will use it but not for everything)
The trios battles from the bad time trio fan game will have attack changes and the attacks will be random
== Story of what happened ==
5 years before Frisk fell portals opened up and versions of boss monsters and other main characters came out of some portals. After a few months of getting used to the new monsters the original monsters accepted what happened and they decided to team up to escape the underground. The humans of each AU all tripped and they all fell into the underground and they decided one of them should take on each battle. There are no links to other websites because this AU is only on this wiki.
