Spiky-Eared Pikachu, in my opinion. You need to have a pikachu from an event to unlock it
arceus can olny be found by buying it honestly who told u that the rarest pokemon are at night misdravios in morning arbork sunkern jigglypuff igglypuff and the rarest twellow
The rarest Pokemon is Dialga
there is no rarest Pokemon you have to train and train and including shinies there is no real rarest Pokemon at all.
mew2 is the rarest
hm....it would have to be.....Spikey-Eared Pichu cause you can't get in platinum diamond or pearl, plus you need another pichu to activate it
There is no best Pokemon on Pokemon HeartGold.
No, you do not need cheats to get the rarest Pokemon. The only way to get the rarest Pokemon without cheating is to go to a Nintendo Event, held every few years or so, and download the rarest Pokemon there. Otherwise, you would need cheats to get the rarest Pokemon.
there is no Pokemon Mansion in Heartgold.
Pikman or Pokemon The Rarest is mewtwo
The rarest is stantler.
They are not in Pokemon HeartGold
