I know that there are 2 super rare ultra powerful Pokemon in the whole entire Pokemon world.Those Pokemon are Raquaza and Arceus, but what i know is that RAQUAZA is by far the most and i mean the most powerful ultra legendary in the entire Pokemon world.
Lugia Mewtwo Mew Deoxys On Diamond, Pearl and Platinum Arceus is the most powerful. You can only get it by using action replay.
You have to find and catch most of them by going through caves, grass whereever, evolving pokemon and trading for them
Go to most caves and you can find a Zubat or Golbat which usually have that ability.
It is not possible to find Walmart in Pokémon Platinum because the store is not featured in the game. You can find Pokemarts in most of the major cities.
in Pokemon diamond ,pearl ,and platinum you find them underground other Pokemon games you are most likely to find them on the ground in small poke balls
The strongest Pokemon in Platinum is probably Arceus, to get Arceus, you need a mystery event, but that event is finished now. :( The second strongest Pokemon would probably have to be Giratina, or probably dialga or palkia.
Golden Arceus
Jasmine gives it to you after you defeat Volkner, to find her go to the northern most part of the city on the ground.
