Chucky
I know the topic has been brought up before and I have two suggestions on how it could work. If behavior acquires the license and uses the "Cult of Chucky" movie as the base they could go two routes.
Route 1: Use the twins and make chucky a legendary skin. This can have variants which they can sell examples are Charles with good guy doll Chucky, Nora with stitched up chucky and tiffany with a tiffany doll.
Route 2: full chapter
Power: They can run the power like the twins except with 2 dolls like the movie. The dolls will have a feral frenzy type ability and be able to switch between each other faster than twins. Even add the power for the dolls to do a mini mori a survivor on final hook to possess them deactivating the doll that doll.
Mori: Have the 2 dolls be auto summoned back and the 3 consecutively stab survivor and end mori with the 3 laughing over body
Survivor: Andy
Map: Either the insane asylum from cult of chucky or the good guy doll factory. Preferably the factory because it would be a more unique map.
Just some ideas because its always fun just to think about new stuff for the game

Don Mancini would be so on board with adding Chucky the tv show Is so good
I think better would be to do it as human Tiffany with a doll for Chucky. Yea, I know that the game mechanic is that you can only control one character at a time, but still think that Tiffany and Chucky together would be far cooler than them able to swap back and forth their own souls.
