Well, I thought I'd never see Rover look so irritated and annoyed. he looks kinda off when he's in a negative mood. I'm so used to him putting out a big smile ear to ear, literally.
Also I'm surprised that Shulk or Face Raiders didn't make it in. Sure, Xenoblade didn't really get popular until Smash came along and nobody uses Face Raiders on their 3DS and all..
There is a list of characters that I regret not including. Shulk is on that list. I also considered Zael from The Last Story and Aeron from Pandora's Tower.
