you get a gba game game boy advance Pokemon game that has mewtwo in it and beat him and catch him then you got to beat diamond and go to pal park and but that game in the lower slot and catch him in one shot from yours truly
You cannot get a Mewtwo in Platinum.
no
without cheats you would have to migrate
No it is not possible.
Mewtwo isn't avalible in platinum (not without cheats anyway) and there is no such Pokemon. I haven't a clue how you've heard of Cyber Mewtwo. Sorry.
you do need cheats
you MUST have a gba slot and migrate mewtwo from the older games it is impossible without cheating or hacking to catch mewtwo in D/P.
there are none
You can't without cheats.
