Licensed Killer Suggestion
I think it would be pretty cool to have Charles Lee Ray (Chucky) as a licensed Killer in DBD. I would imagine walking around as Charles Lee Ray in human form while carrying a good Guy doll in one had by hair of the doll or something and a Knife in the other hand. His powers would be transferring his soul into the Good Guy doll and you would take control of the doll for a period of time then would return to the human body. Not sure but to me it sounds cool, just not sure if the doll alone could work in the DBD world as he is short and could be too OP in certain situations. Just ideas that could be possible to make him work in this world and more iconic killers the better I would think. Im sure you guys could think of something but Charles Lee Ray aka Chucky would be a great addition and possibily the mother Karen or the detective as a survivor.
