(This question does not ask "which legendary is hardest to get.") I do not think that it is possible to say that anything that is legendary is more legendary than another something that is legendary. While some legendary things are more widely known than others, it does not mean that the first is more legendary than the latter. The point is, then, that there are no degrees of the word legendary.
Well the legendary Pokemon is Dialga but most of the other Pokemon are the same.
his name is actually Arceus, and he is the most legendary of legendary Pokemon in diamond. he is only obtainable through a Nintendo event with the azure flute
the legendary Pokemon in diamond and pearl are dialga and palkia.
