You can't, you'll can either trade from a friend who has one or catch it on Pokemon FireRed or LeafGreen and trade it to Ruby. The only other way is to cheat using Action Replay or GameShark.
the mew code for ruby is 71E09BD117FDFD02 and mewtwo is 30621E6F164FED85 these are the right once i think
Only if you have a code breaker and the master code for ruby plus the mew and mewtwo code
the most powerfull Pokemon is mewtwo but people think its areceus when its not on Pokemon explores of time it is darkrai on darkness it is mewtwo on platinum it is mewtwo on dimond it is mewtwo on pearl it is mewtwo on blue rescue team it is mewtwo on red rescue team it is mewtwo on chores black it is mewtwo on ruby it is once again mewtwo i could go on for ever but i am trieng to make my point :)
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.
Go to Cerulean Cave. To get there, you must get the ruby and the sapphire and get the national dex.
you don't get mewtow in ruby
Mewtwo, yes, if you have a FireRed or LeafGreen with Mewtwo.

im pretty sure you can find a mew on mirage island in ruby but im not sure about mewtwo
Unfortunatley, you cannot catch Mewtwo in Pokemon Ruby/Saphirre/Emerald. But you can trade it in from Firered/Leafgreen. Also, instead of asking on Answers for Pokemon questions, just go to Serebii.net
you can not get mewtwo in Pokemon ruby,sapphire,leafgreen or fire you can only get him on pearl ,dimond and platinum
You can't. You'd have to trade it from a Pokemon FireRed or LeafGreen game.

you can get mew or mewtwo by migrating it from Pokemon yellow or ruby or by an action replay code u cant obtain it in the actual game
you have to have beaten the elite four and you have to find the ruby and sapphire for the machine in the Pokemon center on one island. then you can enter cerulean cave and get mewtwo
you have to get the ruby and the sapphire in the seveii islands you get the sapphire in the dotted hole and you get the ruby in mount ember this can only be done if you have beaten the elite four and after you get the ruby and sapphire you can get mewtwo by going in the cerulan cave. hope this helps! :)
