I don't know how I feel about Chrom... I would rather have a more varied character from the franchise, like Micaiah or Sothe. At the same time, I wouldn't want too many characters to be from the same continent... Honestly, I think if I really had to sit down and think about which Fire Emblem character to include (if I could pick just one and Roy counted as a veteran) for the most variety in style, visual appeal, and franchise representation, I would probably pick Ephraim from Sacred Stones.His hair has enough green in it to differentiate him from the other Lords, he's using lances instead of swords which gives him a different kind of style, and he represents Magvel, a continent that doesn't have any reps in the Smash games yet.
I guess he was also one of the Awakening DLC characters, so +10 relevancy points.
