Pokemon Red/Blue Discussion
(it's the second picture)
I've also found a way on the internet how you should be able to catch him..
GO TO THE SECRET DUNGEON WHERE YOU CAN CATCH MEWTWO, DON'T CATCH HIM BUT PLAY THE POKEFLUIT 33 thimes until the screen flashes... THEN FIGHT MEWTWO AND IT SHOULD TRANSFORM INTO MEWTHREE...
I haven't tried the code myself.. because I just started a new game so I don't have al the badges yet.. but I will try this code
I hope that you will let me know if it works
