Okay I made my account JUST to get involved in this thread.
First, no shovel knight ever. All my reasons have already been posted (Western only/Fad/Way better options/it's pretty lame IMO Although I do like his design.)
Second, guys, give up on ice climbers. I love those lil' guys too, but it's too much work for too little. You have to see that..
Third, anyone who said waluigi (that's right I'm not even going to use a capital for his name) on purpose, immediately self destruct. Like now.
Fourth, I'm not at all against all veterans returning. Young Link, Wolf, Roy (meh.) Even if ice climbers we're just Wii U, that'd be cool, but I don't see it happening.
Fifth, does anyone ACTUALLY WANT TO play as K Rool? I don't disagree at all that he could be a great character, but I damn sure wouldn't use him. What would his movement even be? I can see him being a bowser clone minus the fire, that's about as imaginative as I can be with him.
Sixth, Bayonetta? No. Too sexualized. I honestly think the same goes for Krystal. I wouldn't mind either of them but I think it's a valid point.
Seventh, I LOVE the support for this game in general on this forum. You guys rock even if I hate some of your opinions.
Seventh, I know it's improbable, but my vote went to Geno from everyone's favorite Mario RPG, Super Mario RPG Legend of the Seven Stars. I understand the whole nintendo-square thing, but dat moveset. So many attacks, a great ORIGINAL character (HE'S LEGIT A F#&KING STAR FOR GODS SAKE) , great story, cult classic game, veered off the typical mario game and even had a final fantasy hidden boss complete with music and BOWSER IS ON YOUR TEAM. It's 2015. Can we get Geno on this damn game yet or not, because my life literally hangs in the balance.
TL;DR = No to everyone except Geno because of reasons.
