Oh yes.

In the original Japanese version of the movie, Mewtwo is less of a “destroy the world” villain and Mew is less of of an innocent that shows up to save the day.

It’s not quite as big a flip as the person above is suggesting, but it is absolutely more gray.

Basically, Mewtwo is depicted as deeply confused and trying to justify its existence by proving that it and the other clones are superior. It’s not out to destroy anything, he just wants to prove he deserves to exist.

Meanwhile, Mew is actually kind of a purist, claiming the clones are just fakes and don’t deserve to exist. It definitely starts the movie as a vibing space cat, but once it encounters the clones, it instigates the battle as much as Mewtwo does.

I could get into it but this article does a good job summarizing it.
