No, you don't. It has a full storyline in Platinum.
Diamond, pearl, and other platinum versions
Staravia will evolve into Staraptor at level 34. This is for Pokemon Diamond, Pearl , or Platinum Versions. The level may be different in other Pokemon versions.
Yes. It can trade with other soulsilver versions, heartgold, platinum, diamond and pearl.
I think you meant regigigas, to catch it you have to have the three golems, reiice reirock reisteel from the other versions.
UMM..... No way! The only way you can get other Pokemon on your ds is by migrating, or trading with someone else who has a Pokemon diamond, pearl,platinum,heartgold, or soulsilver versions.
Pokemon you can catch in Platinum that you can't catch in Pearl or Diamond are: Tangela Articuno Zapdos Moltres Tropius Regirock, Registeel, and Regice (You have to have a Lv. 100 Regigigas from the giveaway, not an AR one. Otherwise, there's no way to obtain the other three other than migration from Ruby, Sapphire, or Emerald.) There are many other pokemon that you can obtain in Platinum that you can only obtain in one of the two versions, such as Dialga and Palkia, Glameow and Murkrow, and so forth. Hope this helped.
Unfortunately, in Pokemon Black and White, you cannot interact, (trade, battle etc.), with the other versions, (Platinum, Silver, Emerald etc.). only with Black and White is where you can interact.
Manaphy is obtainable in Pokemon Diamond if you also have a copy of Pokemon Ranger. The game Pokemon Ranger is able to communicate with Pokemon versions; Diamond, Pearl, Platinum, HeartGold and SoulSilver to transfer a Manaphy Egg to them. This Egg can be hatched like any other Pokemon Egg.
You can never trade Pokemon from Black to Platinum, because Generation V Pokemon do not appear in Platinum or any other game before Black and White. However, you an transfer Pokemon from Platinum to Black after you beat the game.
These are Gibles Egg moves. DragonBreath Outrage Twister Scary Face Double-Edge Thrash Metal Claw Sand Tomb Body Slam Iron Head This is for Pokemon Diamond, Pearl, and Platinum Versions. The moves may be different in other Pokemon versions.
no but you can get from the other versions
It is possible to trade Pokemon platinum to diamond and pearl, but you cannot trade to any other game.
