You can't catch Palkia in Diamond. You'll have to trade it from Pearl, Platinum, Black2 or OmegaRuby. You can also trade it from HeartGold/SoulSilver, Black, X/Y or AlphaSapphire, if you've visited an event.
no you can't get manaphi on diamond or pearl but if you have a smoochum you can get one, y got a manaphi from Lv.100
You can't catch Charizard in Diamond. You'll have to migrate or trade Charizard to get it in Diamond. You can have a Charizard in FireRed/LeafGreen and HeartGold/SoulSilver and X/Y, if you evolve Charmeleon. To get Charmeleon, you need to evolve Charmander or in X/Y you can find it at the Friend Safari. In FireRed/LeafGreen Charmander is a Starter from prof. Oak and in HeartGold/SoulSilver you can get it as reward from prof. Oak for defeating Red.
If you mean with the 3 legendaries, the legendary bird pokémon Articuno, Zapdos and Moltres: you can't catch them in Diamond. You can migrate or trade them, since they will be roaming Sinnoh in Platinum. You can also find them in FireRed/LeafGreen, HeartGold/SoulSilver and X/Y.
You can't unlock Mewtwo in Diamond, because Mewtow can't be found in Diamond. The only way to get it in Diamond is to trade or migrate it. You can migrate it from FireRed/LeafGreen and then catch it in the Field area in Pal Park. You can also trade it from someone else or from HeartGold/SoulSilver and X/Y.
i cant figure it out
omg y cant i find this answer
In Pokémon X and Y, you may find a horde of Mareep around Route 12.
You can't find a Zapdos on Pearl/Diamond. If you want a Zapdos on Peal/Diamond, you need to catch it in a different game and then trade or migrate it to your game. Zapdos can be found in the Kanto Power Plant in FireRed/LeafGreen, on route 10 in HeartGold/SoulSilver and in the Sea Spirit's Den in X/Y.

I don't think so but check victory road. Y do you need them anyway? you cant catch trainers Pokemon unless you have an action replay
