Darkai sabotages temporal tower where dialga lives and time loses control and so does dialga.
So technically, Darkrai!
You cannot get Primal Dialga in Pokemon Diamond, only in Pokemon Mystery Dungeon: Explorers of Time/Darkness.
You can't get them on any games. Primal Dialga becomes normal Dialga in the Mystery Dungeon Series.
I do have the mystery dungeon 2 and you have to beat the game (beat Dialga) to recruit any legendaries. Or, you can beat the game, beat Dialga to get Dialga, then the same for Palkia, but you never get to actually recruite them, I tried.
No Dialga is in pokemon mystery dungeon explorers of time & darkness
after you have beaten dialga. you and your partner can evlove after you have foiled darkrai's plot and rectuited dialga and palkia
Some legendary Pokemon found in Pokemon Mystery Dungeon: Explorers of Time include Dialga, Regigigas, Azelf, Mesprit, and Uxie.
It depends who your pokemon are. I found him very hard.
As a starter Pokemon you can not be a cranidos in Pokemon mystery dungeon. The only way you can be a cranidos is if you recruit on and make it your leader when you assemble your team at chimecho's assembly after beating dialga
NO
get a fire type partner and a ground type as hero
You can't get Dialga in the start of the game! You can recruit Dialga after the 20 capters in the 2nd story.
no one knows the answer cause no one knows what mystery dungeon 2 is
