apparently you get it in the cerulean cave. i spent hours in there. nothin. so confusing. this kid i know said so. he has mewtwo... i want mew, though you have to admit. mew is better. mewtwo is just a cloning experiment gone wrong. its a freakish mutant. to get to cerulean cave, go to cerulean city. first beat all the gyms. go up the golden bridge. take a left. go down. see the pond? surf it. south south South south left...left....little more..okay. go in the cave. ta-dah.
In a cave?
cerulean cave
Mewtwo may only learn Shadow Ball by using a TM
well first you go to mewtwo's lair this is very dificult click over and over in the top right hand corner of the mewtwo lair screen once you find him teach him toxic and doubleedge go to trainer battle and type"482301" you will battle a guy with 6 shiny blisseys use toxic then use double edge twice then send out another Pokemon and it will die atomatically because blissey will use flamethrower. repeat this until the blissey dies when you do that your mewtwo will be at level 78.
To get mewtwo in soulsilver, you must first beat the elite four, possibly some other things, then go t cerulean city. Go over the bridge, (the gold one, north of the city) then go to the left. surf on the water. (down, left, down, left, so on,) until you get to a cave. You will need rock smash. Enter the cave, and explore. After a while of exploring, you will end up in the basement, (after going to the second floor) and the surf, mewtwo is somewhere down there.
Mewtwo is in cerulean cave, and you can only get Mew through an event.
Pokemon in Cerulean Cave:Mewtwo (average/only level 70)Primape (average level 55)Ditto (average level 55)Kadabra (average level 58)Parasect (average level 56)Machoke (average level 46)Slobro (average level 50)Slopoke (average level 36)Golbat (average level 48)Magneton (average level 50)Wobbafet (average level 58)Note:Don't use a master ball to catch Mewtwo use a ton of ultra balls because you will want to save the master ball to catch another legendary pokemon. You will find it randomly in a pacth of grass. As soon as you attack, it will try to flee so either have a Wobbafet (I don't know how to reall spell the name) or just use a master ball right of the bat.It is in the house directly below the Game Corner. Talk to the guy in the back.
