>>106110610Chucky has been made incredibly more dangerous as time has gone on. By the time you get to Cult of Chucky from 2017, he has an entire army of himself in multiple forms. I'm not sure he can actually die anymore.
In Child's Play 2, his original Doll Body was refurbished by the Toy manufacturers to prove he wasn't a killer. So we learned that providing his body is repaired, he can come back.
In Child's Play 3, we see his original body almost completely melted, but some of his blood gets into the new plastic for the relaunch of dolls. This was enough to have him return, possessing the body of the first newly made Good Guy Doll.
In Bride of Chucky, Tiffany stitched together his Part 3 body which we established is enough to bring him back.
In Seed of Chucky, shit gets wild because Glen/da manages to resurrect Chucky and Tiffany in new dolls that had no biological contact with the two that were destroyed in Bride. So I guess now all it takes is for someone to recite the possession spell onto likenesses of the Chucky/Tiffany dolls. This film also finally shows us the Dolls transferring their souls into a human. Glen/da is even able to split itself into both male and female babies for each of its personalities.
In Curse, we see that Chucky was once again sticthed together by the now Human Tiffany, at the end of the film, Chucky now transfers his soul into a little girl. Hints at multiple Chucks.
In Cult, we get confirmation of multiple Chucks. Chucky can now divide his soul into any Good Guy doll, he can also transfer his soul into any human, even curing them of physical disabilities in the process. By the end of the film, Chucky is is the body of an adult female, with at least 4 Doll Chucky's roaming around. There's also human Tiffany, who split her soul back into her old 'Seed of' Doll as well as the human Glen and Glenda.
So long as a Chucky survives, he just needs to chant his way into another body.
