If you mean the griseous, adamant, and lustrous orbs, it's because if you were to migrate Dialga, Palkia, or Giratina, you cannot transfer any Pokemon holding items, so they give you the orbs to change Giratina to origin form, and boost Palkia and Dialga's attacks. That's really all ^=^!
if you get enough dream orbs the proffesor will tell you
Pokemon Black only takes place in the Unova Region.
Hi there :D i have a eevee and a pikachu is easy to beat a legendary Pokemon all you need is many sleep seed, stun seed, X-eye seed because orbs don't work on legendary Pokemon but dialga will still get sleep status and stun and blind if you throw seed on him :D
you need orbs.
He's a mysterious character and his motivations aren't always clear. The game's just giving you Palkia, Dialga and Giratina's hold items, and using an in-character way to give them to you.
you don't have to to anything with the orbs. They only give you the orbs so if you transfer those legendary Pokemon to Pokemon black or white you can give those legendary Pokemon the orbs.
In black and white, if you ever get the legendary Pokemon Palkia, Dialga, and Giratina, you can give them the orbs, and they'll be stronger.
if you get enough dream orbs the proffesor will tell you
You don't need them for the storyline, you get them so your pokemon can hold them and raise their stats.
Because you can't trade items from the GenIV games, they needed other ways to get certain items into GenV. Since you can migrate Dialga, Palkia and Giratina across, it's only fair that they can still somehow get their orbs in Black and White.
Ghosts can be small white blobs (orbs) Mist (ectoplasm) or in the shape of a person (shadow ghost) Orbs are white but ectoplasms and shadow ghosts can be black or grey
Pokemon Black only takes place in the Unova Region.
So you can give them to Dialga, Palkia, and Giratina
Ghosts can be small white blobs (orbs), just a randomly shaped mist (ectoplasm) or they can be the shape of a person (shadow ghost) Shadow ghosts and ectoplasms can be grey or black, orbs are always white
you cant the orbs are exclusive to certain games
you cant because they gave you the orbs so if you got the pokemon on diamond or pearl you would transfer it to this game and then you give them the orb
