Maxx is my Undertale OC. Except, I don't use her for the classic AU. I have my own AU called Dragontale, which is what I made her for. Maxx is a Nix Dragon. I do ship her and Fresh- (I know I'm weird, leave me alone-)

In her Lore, Nightmare owns her and her younger sister's soul. Her younger sister, Adelaide, is a lot more open to staying with Nightmare, unlike Maxx. As soon as Maxx got the chance, she bolted and never looked back. Due to that, Maxx's soul gets crushed and hurt every day. But she doesn't say anything.

This is Maxx when she worked for Nightmare and was treated like a pet to the Bad Sanses.
