You need to beat all the bosses except for Darkrai.
No,but in explorers of the sky you can recuit him through a special evet.
Yes 'cause I have both Dialga an Palkia!
You get Palkia in a dungeon called spacial rift.
45
its on the deep part 9f
get ready because soon you have to fight Palkia & Darkrai
Palkia can be found in the Spacial Rift when you get taken by him.
go to surounded sea 3f with a mystery part or secret slab
i have beaten dialga but he should be the same as palkia it took me a while but if you have smokescreen then its easy just trust your partner to attack
i have the time version and i saw that Pokemon in dark crater its the place were you battle darkrai. hope this helped.p.s. i got a recuit when i first defeated typlosion
Palkia is level 48
