Reborn of balance

The idea was originally found in A_Bored_Reader Undertale ideas for stories that hit me like the brick called Reborn! I asked permission to use it. Read the original if you're interested, but it contains quite a few spoilers for this story.

Fate got tired of game that own and decided to start a new one.
This battle was bloodier and more serious than ever and the Bad Sans were at a loss.
Nightmare sacrificed himself so the rest of Bad Sans can escape. Error was the only one, who stubbornly refused this and fight whit him to the very end, in the hope that both of them would be able to leave alive.
It's been a while since then. Ink and Dream got together and had a child Palette Roller. And the thing is, Nightmare was reborn as Palette. Fate laughs at him. The new fun no doubt has begun!
How does Nightmare handle the new situation? What about the other Bad Sans? Error? What will happen to the world? The balance? Will Nightmare be left alone? Or will there be those, who stand by him in his fight with Fate?
