I seem to be part of the minority when i say, i dont want them to add 3rd party characters. It just shows that they've run out of ideas... well, running low on the initial premise of smashbros. I want it to be a celebration of Nintendo... nobody else is invited.

But i think Birdo could work (NOT a clone of yoshi), She could do the weird ballarina spin for Down B. And of course shoot eggs (maybe that should be B... or side . And some sort of leap for her Up B, she'd be a slower runner than Yoshi, but heavier set, and would also have flutter jump, im pretty sure i've seen her use it in Mario Tennis and what not.

I'd also like to see Ridley, ... ummm.."it" has become a full beloved character and although not as beloved as Bowser, cmon... add ridley. If mario gets his boss, why not samus. Ridley uses lots of attacks in Metroid games, you wouldn't need to make any up.

Also i can see some Mariokart characters easily being Smashbros fighters (NOT Queen Bee). Drybones, Lakitu, King Boo/Petey Piranha. But we have many Mario characters. Some Zelda characters would be nice, along with a Ganon that isnt a clone of someone. (i'm fine with link having a clone, but thats because in LoZ, Link is strong and fast, you cant have a perfect fighter so you divide their characteristics).
Even the masked kid from Majora's mask ... can't remember his name.. Kid something. or something kid....

Shyguy, being more of a Yoshi's island character than a mario character, may work... may not.

And everyone wants the famous mario RPG character... ummmm, darn i forget his name too. he's magical and his name starts wiiiiiith....... D?

Im not sure if this is owned by Nintendo but Custom Robo... pretty sure it was made by Nintendo. Anyway the main model of custom robo... that'd be a welcome inclusion. Basically any relevant... and a few irrelevant , characters Nintendo created... except QueenBee.

Running out of ideas? Not even close its more fans like those characters to and having them to would make the game even better. Birdo is such a lame character compared to so many other 3rd party characters and those "mariokart" characters are in almost every Mario game work on your arguement

Victini, Roxas, Sora, and Zoroark.

Perfect list for me to

I'm with you on that one. I'm heavily against 3rd-Party characters myself. They've done nothing but ruin the party in my eyes.

Sonic and Snake fit right in whats everyone crying about

I dont see anything wrong with 3rd party i think it helps but whatevas..
i'd like to see
Sora
Roxas (clone of Sora)
Goku
Mickey (epic mickey) or keyblade mickey from KH
Vaati
Cloud
i'd like to see roy, pit, and wolf return.
Crystal (Star fox) would be a nice addition
I'm pretty sure that's it
