The pokemon Mewtwo is so rare because, well, for one, he's a
legendary pokemon, so there is only one. He is the most qwell-
known legendary and has had the most hype about him, so everyone
wants to catch him but there is supposedly only one, which makes
him all the more rare.
Well,if you have the poke radar then you should use it here and
there in a patch of grass and in some patches a rare Pokemon will
apear.(I got 3 rare Pokemon so far using it).For more info please
discuss this with me.
which three did you catch?
