More Smash Bros. Speculation

Hello, my friends of the internet.  I am the BlackCarrot, and I am here with my own speculations on Super Smash Bros. for Wii U and 3DS.  Please remember, these are just my assumptions, and I can be totally wrong on these things, but only time will tell.

Costume Changes

As some of you may know, there are outfit changes for more characters, other than Wario's Biker and Plumber outfit, revealed.  These include:

Little Mac's Wire-Frame and Pink Sweatshirt
Link's Skyward Sword Outfit (b4 his adventure begins)

That makes me think of even more ideas for costume changes here and there.  I have a list here.

-Mario as Dr. Mario (duh)
-Luigi as Mr. L (Super Paper Mario)
-Zelda as Skyloft Dress
-Zelda as from Hyrule Warriors
-Toon Link in his Crawfish Shirt or Hero's New Clothes (Wind Waker)
-King Dedede as Masked King Dedede (Kirby Super Star Ultra / Kirby: Triple Deluxe )
-King Dedede as Shadow Dedede (Kirby 3D)
-Ike as from SSB Brawl

That's all I have on that.  If you have any other ideas, tell me.

Boss Characters

The only one that has been completely confirmed beyond a shadow of a doubt is Yellow Devil.  I want to see more soon, and a list of them on the Smash Bros. home page.  Here's what I'm hoping:

Rayquaza (Pokemon)
Petey Piranha (Super Mario)
Dyna Blade (Kirby)
Heavy Lobster (Kirby)
Eggman Robo (Sonic the Hedgehog)
King Hippo (Punch-Out!!!)
Porky (Earthbound)
Hewdraw (Kid Icarus)
Cragalanche (Kid Icarus: Uprising)
Tiki Tong (Donkey Kong Country Returns)
(A Boss from the Pac-Man series)
(A Boss from the Legend of Zelda series)
(A Boss from the Star Fox series)

Why these characters?  Have an opinion of your own?  Come and tell me.

And you have any thoughts on who should come in as playable, be sure to tell me as well.  I'm always open for a good discussion.  Peace.
