Why do people love Mewtwo so much?
I see people everywhere calling it an example of what a legendary should be like" and saying it's the most powerful legendary and even arceus considers him a god

There's a picture saying "remember when being legendary meant something?" with a large pictures of mewtwo in there
Mewtwo is a man-made pokemon whose existance is only known by the cinnabar scientists and there's no legend about him, how is he an example for other legendaries?

yes I'm upset
