Chrom's supposed to be a combo of Marth and Ike, Frederick is an attempt to make the Seth lightning strike twice, Vaike is a gangster, Ricken is shota, Henry is shota combined with white-haired-pretty-boy, and Lon'qu is a loner. So what kind of audience is Gaius supposed to appeal to? Because I don't think "likes candy" is a gimmick in Japan.
