A wide variety of different Pokemon that cover each others' weaknesses.
Unfortunately, you CAN'T go to the Hoenn region. You get a Hoenn starter by picking stones (red: Torchic blue: Mudkip green: Treecko) but the only two regions you can travel are Kanto and Johto.
Kanto, the games that have kanto are in the order of new to old: pokemon heartgold & saoulsilver pokemon leaf green & fire red pokemon crystal pokemon gold & silver pokemon yellow: special pickachu version pokemon red & blue
Get all gym badges of Johto and defeat the Pokemon league. Then you have access to the Kanto Region.
You can't go to Kanto, but if you have fire red or leaf green you can migrate your kanto Pokemon through the pal park. ^^^^^ YOUR F****NG WRONG!!! you can if you beat your rival 2000 times and have national-dex and beat Pokemon league!!!
Sorry, but you cant enter kanto from Pokemon platinum. Unfortunately, that is only possible in Heartgold and Soulsilver. Hope this helps.
what do you mean by old
Use different pokemon.
No u cant but u can go to Kanto , also get hoenn starters and kanto starters
after you beat red in Mt.silver
You can't.
in my heart
Yes, you do. The starters are Squrtile, Bulbasaur, and Charmander.
You can't. You'll need to trade for them.
only if you trade them from red, blue or yellow
use the time capsule upstairs in the Pokemon center
No. You will need to transfer them over from an older game.
not originally, but if you migrate them then yes.
