Things don't always go as planned.

Frisk wakes up on the cold floor of the Ruins with no idea of where he was or how he ended up there. Luckily a white-furred monster child finds and rescues him. But little does he know that he wasn't meant to be here and that the child he stole this timeline from watches on, silently plotting his revenge. AU in which Frisk takes Chara place (much to the latter's displeasure).

(A fic covering the life and trials of W D Gaster, on his path from quiet country doctor to royal inventor. Contains liberal headcanons)

This is a sequel to UNDERTALE v0,5! The Barrier is broken, and Frisk has Saved everyone she could. But that doesn't mean life is going to be perfect. There's still going to be problems here and there that they have to get through. And what on Earth is a Reset?
