Adventure Mode?

[Locked Achievement]

I had an idea that some characters could end up in outer space, say, Olimar and Lucas could be in outer space fighting some impossible boss (that cannot die) before some other character like deoxys appears and you are then able to kick their ass.

Well, looking at the list of characters, some of them do have some relevence to outer space, so that could contribute to whatever happens along the adventure.

Also, does anyone have any ideas for Bosses?
