Is there a chance? Yes, in the sense that there isn't "not" a chance.There's still a chance that it is it's own pokemon.
I actually liked the idea of combining pokemon BUT it seems to leak far to much into digimon.Has anybody thought that maybe Genesect in the movie (also an artificially created Pokémon) is too powerful and Mewtwo has to combine itself with Mew using DNA Splicers? Let's say it stabilizes Mewtwo's DNA while keeping the enhancements from Team Rocket or something. 1+2=3, after all.
