yes, but not heatwave
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.
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.
Sorry you can't catch mew, once you advance in the game you can catch a legendary/special mewtwo (evolved mew).
no but shedninja can.
Eevee is a Pokemon which can evolve into many different Pokemon. It is capable of learning the move Shadowball.
Gengar learns shadowball at level 45 in fire red, in diamond at level 33
haunter learns it at level 34
You need to use the TM to teach it shadow ball.
I think he would be almost unstoppable if he had those four moves, because my mewtwo has shadowball physic poison jab and thunder and he never fainted
level 42i think
Mewtwo doesn't learn Psybeam.
No, Mewtwo cannot.
No, Mewtwo cannot learn Earthquake. It is a Psychic-type legendary Pokémon and Earthquake is a Ground-type move, which is not compatible with Mewtwo's movepool.
Train your mewtwo it will learn aura sphere at lv 90-100
At level 100
