Also, Unikitty is younger than most of the proper cast, leaving her slightly more..."unstable," for lack of better word. The biggest concept for this AU I have is turning GC from BC's brother, into his imaginary friend(essentially, his morals incarnate), and giving Business the opportunity to "erase" him from existance.
Oh! That is a good idea! Like Good is his conscience as an imaginary friend. That is good, I like that.
