No.
Dialga. There's also Giratina, who is the mascot legendary Pokemon of Pokemon Platinum.
Giratina(Ghost & Dragon)
Well they are the same, but Rotom has 5 other forms and Giratina has his other form!
Only once. Ho-ho and the other Pokemon in the Whirl Island.
yes, the other forms of rotom and giratina's origin from
in Pokemon pearl you can get palkia, giratina, azelf, mesprit and uxie. plus any tht u can migrate from other Pokemon games
Darkrai is good and so is giratina but my opinion giritina is better he can learn shadow sneak and lots of other cool moves :O :D
Well, the Griseous Orb transforms Giratina into it's other forme in Platinum so, you can't actually get a Griseous Orb in Diamond. But if you trade Pokemon with someone who has platinum (and Giratina origin form) you can remove their griseous orb and give it to your giratina, it may change forms.
the main ones are palkia, heatran, giratina, azelf, uxie, mesprit, cresselia, darkrai, and regigigas, and the other regis
those Pokemon are shaymin, darkrai, and the best arceas.
the rerest Pokemon would be a cresselia or a giratina you will need an action replay to catch any other legendary Pokemon
