After you beat the bosses of agiss cave, spacail rift, sory about spelling. Then creselia will ask if you want to go to dark crater. Say yes. You have to get through dark crater then save and go to deep dark crater.
Someone may edit this but you can finally beat darkrai after you beat the ENTIRE game, not JUST the story mode.
yes
when to beat darkri when you beat the whole game you battle darkri when you go to the wonder map what the heck that is not true. you have to do something before battling darkrai
Then you have to beat Darkrai.
You have Pokemon know the move discharge then take out the monster house Pokemon cause they are very weak! Then just go ALL OUT on Darkrai.

You have to beat the game to battle darkrai.
after you beat darkria and beat the final maze do whatever you want in the game.
To beat the game the 1st time, u have to beat Primal Dialga ( not in its normal form, in its Primal form.) To beat the game the 2nd time, u have 2 beat Darkrai and his underlings.
You can't actually beat the game, but the farthest you can go is defeating Darkrai. You can be considered beating it if you beat him.
You get Darkrai at Mystifying Forest 13F, Crevice Cave Deepest Part B2F, Miracle Sea B3F or Mt. Travail B17F
If you want to evolve regular Pokemon you need to get them to a certain level first. If their you starters you need to beat darkrai then have palkia join your team
