>>31729204>>31729344>You cannot keep it in a Pokeball. Anything too powerful would ignore your commands and flee, and the dangerous aspects of it also apply.One of Mewtwo's character traits is a complete lack of empathy, so befriending it and teaching it kindness is impossible. Only the Anime makes it "misunderstood." It's extreme power combined with the fact that it won't care about you means it will most definitely leave you. It might kill you on the way out/cause mass destruction on the world.
Nihilego comes from a different dimension and would take a long time to properly acclimate to our world. Combined with the fact that it's a parasite, so preventing it from bonding with a host is probably unhealthy for it. It's also very powerful and may not listen/escape and turn someone crazy. Hell, since you're around it most often I'd say there's a good chance that you'll get possessed and go crazy.

Assuming Pokemon in this scenario can still evolve, Haunter/Gengar become active predators on living beings. Very dangerous for you or others around you.
Ninetales would probably straight up die in a desert environment. If it has it's Hidden Ability constant hail while it's around would get real fuckin' old.
Silvally would be hard to attain as it needs a strong bond, and even then the game doesn't say for sure whether or not Gladion's Silvally is still in total control of it's power. If it loses it's shit on you or someone else there is no healing magic in the real world.
Stufful would be dangerous as fuck. If it evolves, all you got to do is get Bewear excited and it accidentally kills you. Bad choice.
