If you beat Dialga and Dialga faints, you can no longer catch it.
He only unblocks you when you either catch Giratina/Dialga/Palkia for Platinum Diamond and Pearl respectively, or beat them in a battle. He won't let you cross until you do so.
You can't.You can only get to it on Pokemon explorers of time/darkness.But you can still get Dialga on MT.Coronet,by getting its orb and going to the peak of the cliff.You do the same with Palkia.
yes he will be standing in the same place not in firered, leafgreen, emrald, sapphire or ruby just platinum diamond or pearl...............find out yourself
Yes you can catch the three Legendary birds in Platinum but you'll have to beat the game first and to minor side activites before hand
as long as you haven't beat it yet and you have the azure flute, you can.
If you play Pokemon get a life if your dont then get a job still Oh yeah yes if you want viruses in your comp
Yes
Yes. Its basically the same game but with a different format. Like the gyms and the background in battles and also the cities (although they still have the same name.)
I don't know who started the rumor, but you don't need any member of the trio to catch Palkia or Dialga in Diamond or Pearl. (I know because I caught Palkia yesterday, and I didn't even have the DEX visual log for them). Sad for you though...but Uxie or Azelf are better than Mesprit for battling in several situations. Find someone on WiFi willing to trade if you really want one.
it is not if you use a net ball twiceResponse from creator: I tried every single kind of pokeball there is in Pokemon Platinum at least five times except a master ball. Which means i tried the net ball at least five times, i still didn't catch him therefore, until there is an answer that actually works, i still think Heatran is impossible to catch and i still ask why. WHY!?
yes by trading. the event is over already ---- It's still possible in platinum. You can catch the three Regis then bring them over to the ice temple in snowpoint. - MeritBadgeHelp
it holds dialga still so team galactic could have dialga's power
