Every... FE7... Character... *squee*
Well, more like 10 characters from FE7. To be more specific: Eliwood, Hector, Lyn, Matthew, Serra, Florina, Nino, Jaffar, Karel and Nergal. They all can be enemies for skirmishes, sell items or even join the player's party (Yes, even Nergal).
I guess these spotpass characters don't have support conversations ? Would have loved to do some pairing (like Serra with anyone, Lucius and Frederick... What ? I ship whoever I want >.>).
Gee, I need this game. Badly.
Yeah, no supports you can play around with the Hubba Tester, but that's it. They can class change freely though to make up for their lack of supports, generally have great growths and every single one starts already knowing one skill from outside of their own class.
Like say, Jaffar has Galeforce, which allows him to move again after killing an enemy. That's usually a Dark Flier-exclusive skill and takes a lot of grinding to give to male characters through breeding, but Jaffar just starts with it in addition to the Assassin's skill set. The lack of supports gives them a disadvantage compared to the main cast, and generally well prepared 2nd generation characters will be better than them, but I think they're close enough to the first gen.
