Jawbreaker

From designer

Jawbreaker is the daughter of Pinkie Pie and Discord, and is a chaotic entity who loves to have fun- even if that means that somepony else doesn't. Her idea of entertainment is wild and chaotic, and in the past she has enjoyed watching ponies struggle in the chaos she creates. She's the guest of honor at all of her parties, and she makes sure that one of her 'guests' ever forget that. She's not necessarily malicious or hateful- she just doesn't care enough about other creatures to sacrifice her fun for their wellbeing. 

From owner

Jawbreaker is just like what the designer says!!The things I add are:

She suffers from Bpd(don't worry I have it ill do my best to write it good)and derealization!!Thanks to her derealization she is very apathetic due to not being able to connect to other ponies.

Jawbreakers parents weren't the best,in the au she comes from Pinkie Pie is an alicorn of fun who had a child with discord.She never really had them around as they were always busy either causing chaos or partying. This caused her to have abandonment issues and her bpd.She was a wild child trying to get her parents attention but never got it.

They didn't even seem to notice when she left their dimension.
