This mod makes the Fire Emblem characters say "NANI?!" when they counter.
Note that Lucina has a strange feature where sometimes her counter makes no sound at all. This is not something that can easily be changed, nor do I know what game files cause a character to play or not play a sound clip.
Love the idea, but it doesn't really work... Ike didn't work at all, and Marth's "NANI?!" went over all his aerials and not his counter. Also, this would be better as a SFX pack imo since this kinda makes it hard to have voices over characters while also getting the "NANI?!" (most of my Marth, Lucina, and Ike costumes have custom voices)
