I wanted to try as many Pokemon I've never tried before in Kanto, so I'm playing Pokemon Green, this is what Pokemon I'm going to have.
TENTACRUEL
ONIX
PERSIAN
RAPIDASH
MEWTWO
PINSIR
Until I get Mewtwo, I will have either:
ALAKAZAM
OR
GENGAR
I will have to cheat to get them, tough. Which one should I get?
