1. Marx from Kirby. In his small, deceiving, cute form he could be like a slower, but more powerful and bulky version of Kirby, with his own moves and stuff.
His final smash could be his true form, that would be sick... Seriously, on the big screen with the graphics of the WiiU, they could make him look creepy as hell. Also, they could give him a cover of his theme to play over the stage music when his final smash is active.
Also, if Marx is over a certain percentage of damage before using his final smash, something like 150% - 200% maybe, he'll turn into Marx's soul, which will be an even more powerful and fast version.
Yes, I am a bit of a Kirby fanboy. Speaking of Kirby, and yes I'm about to ramble, Nintendo NEEDS to make a 3D (by that I mean non-side scroller), open world (not like TES, but you guys know what I mean) platformer Kirby game for the WiiU, and make it have varying difficulties, the last one being hard as fuck... Seriously, fans have been requesting a game like that forever now, and with the WiiU, that's FINALLY possible. It would be a huge success, and no one would undermind Kirby as a kids game anymore... Ugh, it just frustrates me. I'm an over dreamer about video games, I know...

2. Crono from Chrono Trigger. Need I say anymore? It's self explanitory, really. I want it, you want it, your uncle's cat wants it, I could go on but I think you get the picture.
There are so many possiblities for what moves he could have at his disposal, that being said, if they had the rights to do so it would be extremely easy to make him a really good competitive character, on top of the fact that he'll be a fan favorite already... Also, Chrono Trigger is on the SNES and DS, both Nintendo consoles, and is considered to be one if not the greatest game of all time, so why in the absolute FUCK would they not add him when the opportunity and want for him to be in it is RIGHT THERE IN FRONT OF THEM?!?!? Make it happen Nintendo, make it happen...

3. Commander Shepard. They made Mass Effect 3 for the WiiU, so why not? I think he would be a really cool character to play as, because the Mass Effect series is awesome. Sure, the end of the third one sucked, but even that was fucking epic and hauled ass up until the last 5 minutes... For those wondering about his appearance, they would just use the signature, default male one. Those of you who have played the game, you know that there are a lot of classes. His moves could be a combination of many different biotic and tech powers from different classes, and he could also have a gun, most likely the Avenger, as that would make the most sense. His 'A' attacks could be dual weilded Omni-Tool blades. It just seems like a good idea to me, as I said before, it came out on the WiiU upon its release, and Bioware would probably be all for the idea; they need to win back fans some how...

4. Doctor Phil, he could talk to people about there issues instead of fighting them.
I don't have any more at the moment, but I'm sure I'll think of some later. As I do, I'll post them here. It's nice to be able to see everyone's ideas and stuff. <
