Question: Could Big Mom make Kuma normal again?
Define normal. Do you mean take his soul from his body and give him some remnant of his original personality, but still be under her control as opposed to under the control of his programming?
Like he was before Vegapunk made him a full Pacifista.
Well, I had an interesting idea about Kuma (this is pure speculation, and not necessarily true).
I was thinking that what Vegapunk was actually trying to do with Kuma was somehow remove his devil fruit. This is something that has never been done in the series, and isn't even considered possible at this point in the series.
I don't know why Kuma would want his devil fruit removed, but I can't think of any other reason why Kuma would be turned into a full robot.
If Kuma's original body that contains his soul was disposed of, then no, cuz his soul is had rotten along with his old body and is now in the afterlife.
If at least his brain was preserved, then it's possible to restore his original self again, though whether he'll came back right or wrong is another question.
I don't think so. At this point, Kuma is full on robot, no flesh remaining. Robots don't have souls, presumably. On the other hand, seeing as how Kuma is inanimate, maybe she could put some other soul/personality in him. But his? And normal? Methinks not.
What do you think?
