My new Undertale AU concept! (PvP + Story)
Heya! I’ve been working on a new Undertale AU concept that mixes original storytelling and competitive PvP gameplay, and I’d love to share it with the fandom
You’re not the vessel — you’re the soul.
Your vessel (human or monster) has no mind, only you control it.
Choose your soul color (each type changes your attacks), and build your story.
You can optionally choose to have a nemesis — a rival you might love, hate… or kill.
Mainline mode = branching endings, depending on your choices.
Arena/Ranked = use your vessel, or AU characters like Ink, Error, etc.
AU fighters don’t have full stories, but they were summoned by Gaster to join this eternal tournament.
Different soul types = passive bonuses & gameplay variety.
Here’s a sketch of my concept layout
Let me know your thoughts!
