After beating a pokemon, he or she will ask to join your team and you can either say YES or NO. Hope it Helped.
NO!
If you mean Explorers of Time/Darkness, go to Temporal Tower, beat Dialga. Then go back and fight it again. Beat it. And tell it to join you. Well yeah pretty much what he said but I would just like to add one thing: No matter what-even if you have the worst luck ever-Dialga will join your team since it is one of those Pokemon that have a 100% recruit rate Have Fun! ;P
It makes it easyer to recruit Pokemon but does not effect Pokemon on the never join list.
arceus isn't in Pokemon mystery dungeon 2. he is maybe in Pokemon mystery dungeon 3.
evolve your main characters and try to "join 'em all"
