I'm sorry.... /[Batman/Bruce Wayne x Joker/Jack White]/

This is a story that goes like [Friends to Strangers to Enemies to Lovers (possibly)]

Characters:
Batman = Bruce Wayne
Joker = Jack Oswhald White (yes this is confirmed in the comics)
Harley Quinn= Harley Quinn
Alfred Pennyworth (probably won't appear so often)
Robin/ Kid Wonder= Dick Grayson
Other villains would be specified.
Diana White= Joker's/Jack's sister
Minor characters with appearance in 2-3 chapters
James Gordon= Gorham's sleep driven commissionaire
Barbara Gordon= Gordon's daughter

This from the Lego Batman Movie not from the games, Comics or the series.

It would be based on Joker's past (in my AU) and Bruce's past.
In this story Joker is taller, i know he was confirmed to be 6'5 but he will be taller (6'9).
Batman is to his original height (6'2).
Also i will combine some other fandoms in the making of this, especially for the lore.
