Nothing. Well at least not that I know of.
Team Raider is at the beach because Digletts dad, Dugtrio, was training at the shore and he was drowning so when Team Raider got there they saved Dugtrio.After that i don't know what happens, Sorry:(If anyone knows please post the answer to:"what do you do after Team Raider is at the beach?"
Cant
Ask why they appeared
nothing
No they just stay ther
If explorers of time and explorers of sky are the same, I think you can't fight team Raider.
after you have defeated darkrai team raider will be on the beach apparently having helped dugtrio out of the water Raider not raidiator or whatever you put

Sorry, but you can't. It turns out that they just stay there for some odd reason. I think it's because if you were to talk to wigglytuff after you finished the game, he says that you will be as successful as the incredible team raider. And if you were to talk to one of the members of team raider, then he'll introduce him and say that they're the best exploration team ever. just so that you get an idea of who exactly they are. >.
After you have beaten the game, go to the beach south of the Guild Hall, Where you first met your partner. You'll find Team Raider standing there.
on the beach after marine resort is unlocked
nothing just do missions recruit
