NO The Pokewalker was made especially and only for SoulSilver and HeartGold, so the only way you could walk a Pokemon from your Platinum game is if you traded that Pokemon to SoulSilver\HeartGold and then transfer it onto the Pokewalker
You could find wild Growlithes in Route 48.
Diamond, Pearl, Platunum: You can only go to victory road. Heart Gold, Soul Silver: You could pick Victory Road, Kanto or Mount Silver(Kanto and Mt. Silver roads will be closed(Kanto Closed for time being and Mt. Silver needs Scary Strong Pokemon)
I don't think you can get Latios in Heartgold legitimately. I'm pretty sure you can only get Latios in Heartgold by using an action replay code, such as the Pokemon Modifier Code. You could also trade it over from Soulsilver, I think.
You can get a Munchlax by breeding it with Snorlax holding a Full Incense, or you could transfer it from the Poke Walker.
You could get the super rod in Olivine city (heart gold)
You can't. Whoever told you you could is messing with you
two, johto and kanto. you can go to kanto after you defeat the elite four in johto. Yeah. Wish I could catch Ho-Oh. un less you count singho ruins that is kind of part of the siniho region so you can go to three bacicly.
well if you beat Red you get one of the kanto starters so if you choose charmander you could evolve him into charmeleon then into charizard
You can't, I wish you could though. You might be able to by event, but nothing I ever heard of.
One is from the elder sage when you beat him at sprout tower or you could buy it from Goldenrod department store for 2000PD, if not, go to Celadon and buy it there(Celadon is in the Kanto region).
Actually, I think it's on the high side. In Pokemon Red, Blue, Yellow and Green, (JP) Johto Pokemon weren't yet invented. But in Pokemon FireRed and Leafgreen, you could find Johto Pokemon in the wild as well as trade Hoenn Pokemon from Ruby, Sapphire, Emerald, Colosseum, and XD later in the game. Since HeartGold and Soulsilver are remakes, much like FirRed and Leafgreen, their will probably be Johto and Kanto Pokemon like Gold, Silver and Crystal, along with Hoenn Pokemon later. Then again, FireRed and Leafgreen had Johto Pokemon only on the Sevii Islands. HeartGold and SoulSilver probably won't have the Sevii Islands, but will have Kanto. Since you could find Johto Pokemon in Kanto in Generation II games, you should be able to find Hoenn Pokemon in Kanto. Just another guess. Hope I helped. Thanks! Yes.There are a bunch of hoen Pokemon in HG ans SS. Including starter Pokemon (treecko, torchic, and mudkip) which are given to you by Steven Stone after you beat Red on Mt. Silver.
more than likely not but if you are able to go to other regions could you tell me how cause I have it and I havent yet
If your Starter is a Charmander, then Suicune will be roaming around the Kanto region just like Cresselia in Pearl and Diamond.
You cannot catch a charizard in heartgold,HOWEVER,once you beat the Champion/E4 you can go to Kanto,And go to Pallet town,you will eventually be able (After i geuss you could say,a mini-quest.) to pick a Kanto starter (Bulbasaur,Squirtle,Charmander),you can then level it up to the proper level and you will have obtained a Charizard. Hope i helped.
To get a Mew in Pokemon Heartgold, you could do it through a Nintendo Wi-Fi event.
Sorry but you can not get to Kanto in Emerald Maybe you're thinking of Pokemon Gold, Silver, and Crystal were you could go to Kanto. Just to clarify Kanto is the setting in Pokemon Red, Blue, Yellow, Fire Red, and Leaf Green.
