>>39470951Mewtwo likely contains some of Ambers DNA which explains his apperance (or Fuji's which would explain his personality). Regardless its likely he has human DNA in his make up, the rest of his DNA contains all the information for every other pokemon....
To wit.... Mewtwo probably could have a human child though unfortunately not by copulation, more genetic splicing on the DNA of the second parent, put into a egg, electrically stimulated to divide then gestated in a vat or surrogate womb... or the mothers womb if the second non-mewtwo parent is female.
