yes
You just have to keep defeating it. It will offer to join if you are lucky.
Do they have to ask you to join or can you let them join by doing something
Arceus is not in Explorers of Time or Explorers of Darkness. There is an Arceus statue in Explorers of Sky, but there is no real Arceus that will join your team.
he has to join u then complete the game and change to be him
your leader has to beat them,then they will ask to join your team (in aegis cave)
you can't he disapears, taking dusknoir with him ;(
After when you have beated you have to talk with Cresselia. She wanna join then. hope it helped
To make Zapdos a recruit of yours in Ex of Darkness you go to the Amp Plains and on the 7th floor you will run into him.
Same way with blue, red, time, and sky. There's a specific chance that one will ask to join.
I can't remember at what point he joins your team, but if you keep playing the story line, he will eventually join, I think.
You can evolve after you beat darkai and get dialga and palkia on your team ( they join after you beat them the second time.)
you don't battle it you talk to it at sharpedo bluff after defeating darkrai in the dark crater and it will ask to join.
