Hi everyone, I had read that Disney was originally going to make a sequel that features Gaston's younger brother, Avenant. Now, here are my suggestions on the sequel if the midquel have not been at all.
Turning the Prince back into the Beast
Avenant's motive was to harm the relationship between both Prince Adam and Belle by turning the former back into the beast! Belle will have to start from scratch by breaking the spell, and both tried stopping Avenant along the way.
He Kills Belle
I read this from a fan-fiction site many years ago and my suggestions is this, Avenant participates in a cult...
