Hi!!! I'm finally working for a ending to this series.After debating, these are the endings I'd like to see. If you have any ideas or suggestions about the endings, feel free to share them in the comments.
Deku ends up completely controlled by AFO. Together, they use her power-filled body to dominate the world, finally Deku becomes AFO's wife, having multiple children with him...
AFO takes all of Deku's powers by absorbing her and transforms into the biggest and strongest, villainess of all, defeating Deku and subjugating the entire world...
Deku confronts AFO, and defeats him, after that Deku uses her absorption power and absorbs everything around her, every living being, until she becomes larger than the planet itself, transforming into a universal goddess who will recreate the universe...
Thanks to her classmates, Deku is freed from mental control and the need to absorb others, and manages to split her body into multiple past versions of herself. Each version of Deku marries some hero...
AFO uses a special technique to remove all of Deku's excess power, returning him to normal, and takes all those powers for himself. But he can't handle it and explodes, causing all the girls that Deku had absorbed to return to normal, Deku apologizes for what happened and everyone is mad at him...
Also, this series was initially going to end in part 5 with a different ending. If anyone would like to see the drafts of that ending, let me know.
