ANSWER 1:Mewtwo appears only in Fire Red and Leaf Green. You can catch him in either of those games and then trade him to Pokemon Ruby.sorry mate its impossible only way is to trade like this guy said (: (: (: (: (: (: (:ANSWER 2:I regret to tell you that you cannot catch Mewtwo in Ruby. You can only catch Mewtwo in FireRed or LeafGreen. (You can use cheats to get it but it wouldn't be as fun).Mewtwo is at Level 70 in LeafGreen and FireRed so use an Ultra Ball/Timer Ball/Master Ball.If you need/want a Mewtwo you can trade Mewtwo into your Ruby/Sapphire/Emerald Game.
You can capture Mewtwo in Cerulean Cave B1, Zapdos in the Power Plant, Articuno in Seafoam Islands B4, and Moltres at Mt. Ember Peak in FireRed.
Migrate from FireRed. It's easier to get Paras in THAT game.
To catch Mewtwo in LeafGreen or FireRed no. To migrate Mewtwo from LeafGreen or FireRed to Diamond/Pearl/Platinum yes you have to have it in Diamond/Pearl/Platinum.
