Answer 2

Mewtwo in cerulean cave

Before you attempt to catch mewtwo bring lots of dusk balls and a Pokemon that knows surf (and lots of max repels if you hate weak Pokemon)Then go in the cave and once youre in the water,surf all the way to the end of the path (WARNING:do not go up any of the stairs you got off the route to mewtwo).Go onto the land again,go up the steps and, head right ,than up,than go down the steps,head right than up another set of steps,and go up the ladder(easy eh?not really it took me hours too get it straight).

You'll now be on B1,Which is like an crystal maze (is not rock so bont use rock smash).Head left until you come across a fork path ,than go down,right,down,right,down,and right.Than go all the way up until you cant go any farther and finally,go all the way to the left and down the ladders.

Go down the set of ladders below you and you will be on B2.From here, follow the straight forward path all the way toward Mewtwo, who is on the island at the very end.

Mewtwo is an level 70 so you need youre strongest Pokemon Mewtwo knows the moves psychic ,Mist, Future Sight, and Psych Up.

-POKEFREAK O.O
First you have to defeat the elite four.Next you have to have the national pokedex.Then go to celio and he'll tell you where to get the ruby and saphiere. Once you do that go to the crulean cave....then your on your own finding him in the cave.
