>>40733377>Cloning a godOh, it's worse than that in the games.
They managed to capture a live Mew, inseminate it with its own clone (Dolly the sheep style) or a "natural" child, then took the child/clone Mew and used it as their guinea pig for turning a genetic free check of a pokemon into a pure combat machine. The gene splicing and DNA editing experiments are explicitly said to be horrific and went on for years.
And unlike the contemplative anime Mewtwo, this mutant is supposed to be a savage that thinks of nothing but battle.
