First, you defeat Dialga so you can prevent the planet's paralysis.
Second, whenever you have free time, go back to Temporal tower and Dialga will say something like "I know why you came here: so you can challenge ME!" then you defeat it again and it will join your team. I hope this helped a little!
well...I still can't find how to get to Temporal Tower again!!!! >:(
yes
crevice cave and blizzard island, after you beat dialga
You can't get Dialga in the start of the game! You can recruit Dialga after the 20 capters in the 2nd story.
No. Primal Dialga becomes normal dialga when you defeat him, so its impossible to get Primal Dialga unless you cheat somehow(if you can).
you have to defeat him again after graduating from the guild and he will join you
No. None of the future pokemon disappear except for Primal Dialga, who is replaced with a good Dialga.
If you mean the dungeon where Dialga is, between 10 and 13.
NO, Unless you have Dialga Lv 56 and Palkia Lv 85
First you have to defeat primal dialga to save the world and to continue the story. later after the credits roll, if you want to recruit dialga, you can battle him.
You can't, n00b.
Primal Dialga is the evil form of Dialga, and can only be seen in Pokemon Explorers of Time or Pokemon Explorers of Darkness. Primal Dialga looks just a little different than the original Dialga. Don't forget he can be found in Pokemon Explorers of Sky as well. He turns evil when time appears to stop. But after you defeat him, he will just fall on the floor (wtf?) but that will give you enough time to fix time, then he will become regular dialga. You can visit him again later to catch him, but i forget how. Also, there is no way to change dialga into primal dialga after you catch him.
I have sky and I beat dialga when my partner used shadow ball and he was defeated also bring lots of reviver seeds
