How would you guys react if this was the Assist Trophy line-up?
I would be almost completely satisfied.
Let me break it down.
Bowser Jr. - Arguably the only remaining main character from the Super Mario series (read: the platformers, not Kart, sports, Party, RPG, or other spinoffs) who hasn't been featured as more than a trophy yet. I could see him as possibly playable, or else definitely an assist.
Paper Mario - would be the first alternate version of a playable character to be an assist. Somehow that seems wrong to me. He'd be better off playable, or as the most complicated alt costume ever, complete with different moves, but that will never happen.
Waluigi - Hey, what gives? How come Dillon gets individual fingers? WAAAAA! Waluigi hates this game!
Cranky Kong - So much yes. If he isn't playable (which could totally happen, right? ...Right?), I totally want him to be an assist, sitting in his rocking chair, talking about the good old days, until someone attacks him, at which point he would jumps out of that chair and retaliate. Would love Rambi, too.
Fire Emblem ladies - makes me hope for someone more unique than Chrom to join Marth and Ike (I don't hate him, he just seems boring standing next to them). But I approve.
Metroid assists - I see you didn't add any new ones, which I think is realistic and okay, since those three are a great selection.
Zelda assists - those would probably be my top picks to represent the N64, GCN, and Wii eras of the series, but I wonder whether we couldn't have an older rep, as well. Some 8- or 16-bit enemy. Would also accept Groose if Ghirahim is a fighter or boss or something.
I approve of everyone after Tingle all the way up to Isaac, and would be pleased to see them and not too let down by any of them not being playable, but ...
Isaac is my most wanted newcomer, and I really hope to see him, possibly with his Dark Dawn design as a fighter, with Matthew taking his dad's place as assist. The only other character who I could possibly be more excited to see would be a Melee-intro sized, Brawl-styled, Super Metroid-inspired Ridley, who I sincerely doubt will make it in now thanks to that eye-scarring, pitiful excuse for a Ridley clone we saw in Other M. The only way I can prepare myself for that disappointment is to tell myself every time I think about it, that if Ridley is playable, he will be Roidley instead. Which is the only think worse than Roidley being a boss. There, I... I said it. /unnecessary rant
Ray - I also hope to see him playable, but won't be heartbroken if he's only an assist.
As for all the rest, I approve very much and would be excited to see so many retro reps, especially Muddy, who is awesome, and Sheriff. Though I would rather see Tails than emo-punk-LOOK I'M ANGSTY-Sonic-palette-swap. No offense to Shadow fans, I've just never liked him. At all.
Also, Proto Man and/or Zero would be cool.
Also also, Andy could be a cool fighter.
