The Multiverse Prison

An alternate Undertale multiverse where all the 'bad guys' of the multiverse are thrown into a high security prison, to keep the peace of the multiverse.

Some of the more infamous inmates are:
-Nightmare Sans
-Killer Sans
-Dust Sans
-Horror Sans
-Error Sans

There are many more criminals who fly under the radar, wanting to just serve their sentence with as little issues as possible.

Then there are the two who are kept in the heaviest confinement and permanent solitary. The other prisoners and all civilians have no idea the true extent of their power or crimes... only the ones who detained them truly know.

And then there's you. Y/n, the fifth human to ever be detained in the famous prison. Nobody knows what you were detained for, but there certainly were plenty of whispers and rumors going around when you were led to your cell. A higher security one, you and everyone else noticed.

You're going to escape, of course. You just need to find fellows with the right specialties to assist you.
