What are the limits of Nightmare Forms?
"it could cause their abilities to realize any doable feat from their respective realm" is what Charlotte has to say about them but I feel that isn’t it.
In the Sans vs Bendy videos Sans gains a Nightmare Form aswell as Bendy however despite being very much on the ropes Sans never once utilised his ability to reset. Instead having to be saved by the bell with Bendy overheating himself.
And it got me thinking, what are the limits? What decides too much for a Nightmare Form to give? While it doesn’t allow you to save and restart it does allow you to interfere with save files as shown by Sans and more importantly Springtrap (because he isn’t from Undertale and he actually is the only one confirmed canon for the series)
But it has me wondering if characters like V1 or Zagreus will gain the powers of God or the Gods and Titans.
While I think the answer is ultimately whatever MORØ decides is cool so I’m not too fussed, but it would be cool to see what other people have to say.
