Happy Day!!
I was never convinced for a second that ICs would be cut. They are too unique, it would be a shame if they didn't make it back. I loved using them.
I wouldn't mind some tweaking, though. Maybe if Nana is a little better at staying nearby, or if some moves, like the down b, were a little more useful, they could be even better!
I wouldn't be surprised if their FS is a blizzard that freezes enemies. That would be appropriate. It would be so cute if it left little bits of snow that linger on the stage after its over!! awww! Those ICs are too adorable!
Also, are Nana and Popo sister and brother, or are they Gf-Bf/ wife-husband? Is it officially stated anywhere? Let me know.
