In Gen I it was originally said Mew gave birth and Mew's child was experimented on and became Mewtwo, though since then that story was retcon to Mewtwo being cloned from Mew's DNA.I have an odd thought. My theory found within the hide.Mewtwo is a result of horrifying experiments involving gene splicing. It's possible for living creatures to have a body different than what its genes are, via surgery. What if the Mewtwo we know is just a surgically altered body? I would like to point to mega Mewtwo Y for why I thought of this. Out of the mega Mewtwos, Y is more "natural". The mega stat allocation and type are why I think this. Mega Mewtwo Y also looks like a horrific genetic abomination. When a Pokemon mega evolves, you draw out its true power, which in Mewtwo's Y mega's case, brings out a form closer to what its genes are.
To summarize, I theorize mega Mewtwo Y is the true genetic form of Mewtwo, and I think the base form is a surgically altered body. The base form DOES have an extra spinal column, after all.
As for the X mega, I have an entirely different theory about it.
