Multiverse(horror)

So this is a multiverse horror story. This is just an idea of a roleplay game I made with my sister and I thought it was fun. Soooo..... You and a lot of other characters from different universes are stuck in a mansion full of monsters, demons, or anything you can think of that'll try to kill you and everyone else. (The characters and what universe they're from): Murder Drones: Uzi, N, V, J, Doll, Thad, Lizzy, and Tessa. Hazbin Hotel(I'm sorry if I spelled that wrong): Charlie, Vaggie, Angel Dust, Husker, Alastor, Lucifer, Nifty, Adam, Lute, Vox, Valentino, and Velvett. Helleva Boss: Blitzø, Moxxie, Millie, Loona, Stolas, and Octavia. Countryhumans: America, Russia, Mexico, Canada, France, Germany, UK, Ukraine, South Korea, North Korea, Romania, and China. Kpop Demon Hunters: Rumi, Zoey, Mira, Jinu, Abby, Romance, Mystery, and Baby. My Little Pony(for my sister's sake😑): Twilight, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy, and Rarity. Sprunki: Oren, Randy, Clukr, Fun bot, Owakck, Vineria, Wenda, Pinki, Jevin, Black, and Gray. Call of Duty: Price, Ghost, Gaz, Soap, and Makarov. That's it.... Add whoever and whatever universe you want. Also let me know who I forgot to put in.
