That's a matter of opinion(myne is Giratina)
arceus
a lot of legendary Pokemon
That would have to be Dialga.
there is no best spot
Either moltres or infernape
Pokemon mysery dungeon 2 and Pokemon pearl-diamond
try serebii.net its got a lotta Pokemon stuff
a red tent
I would have to say spiritomb because nothing is super effective on it. p.s spritomb is not a legendary,but some people say he is
there are many legendary Pokemon in Pokemon heartgold, but the best is HO-OH
The best Legendary Pokemon with the best stats is none other than Mewtwo.
Whats youropinion? Id say Diamond because of the upgraded graphics.
