Well, i was bored and since we're closer to the release date i think character predictions are easier.
So let's get started.
Mario Series
Mario
Mr. Video Game is back to kick third party ***.
What's there to say about Mario inclusion in Brawl? Nothing, he's Mario.
Luigi
Luigi will be back.
Come on.... he's Mario's brother.
Peach
Our Favorite princess is back, with a sexy attitude. The only changes i can see for peach is to nerf her down smash, seriously... she has down smashed my whole family.
Yoshi
Winged Dino chickens... in Brawl? welcome to smash kid. The little dino/dragon thing is back, with a third jump? maybe it's just me, but did yoshi really need a third jump?
Wario
Wahahaha!.
While Wario is not my favorite Mario character(the prize goes to Mario of course) i can tottaly see myself maining him, just for the fun factor. Seriously... you can kill Ganondorf with a Nuclear waft?
That has win written all over it.
Bowser Jr.
Bowser Jr.... it seriously takes some brains to use a paint brush as a weapon. He would be unique and i guess a little fun to play with. Good chances? Well... he's Bowser's son, a main villain in a REAL game and has a small fanbase.
Bowser.
Bowser crawls back from the lower tiers... with a gigantic vengeance.
When i played Melee for the first time, the first character i used was Bowser, and i was very... very dissapointed to see the big bad koopa king be such a weakling. Of course, it seems Sakurai noticed this, Bowser is back, and more angry than ever.
Pokemon.
Pikachu
Awwwwwwwwwww isn't he cute? think again. The electric rat is known worldwide, and is back with a vengeace.
Jiggs
To all those Lucario fans thinking that Jiggs whont be back... it whon't happen, Jigg's IS part of the smash world now, seriously i still remember when i beated Classic mode for the first time in the 64, only to find myself unlocking Jiggs, and again on Melee. And will happen again in Brawl.
Mewtwo
"Wich of you will opose me first?"
Mewtwo is the only single pokemon made of pure win and Ownage, the first super powerfull pokemon and still, one of the most powerfull pokemons, i can easily see him back, why? he had an original moveset, has a fanbase, is popular(come on... he is known worldwide) and bonus point:
"He was in Melee"
There's no reason to cut him, "lol he was too weak" So was bowser.
Red(Pokemon Trainer)
"No way! The Pokémon Trainer has finally arrived."-Sakurai
I almost had a heart attack when i saw the update, was it just me? of course not, who saw it coming!? this was the biggest surprise Sakurai could have though of.
Pokemon Trainer... i bet he is going to be a very popular choice.
Lucario
I despise all pokemons that doesn't belong to the first/second generation, but Lucario is the less pathetic one. Hadooken throwing dog? whatever. At least has a chance of getting in with Deoxis and Munchlax deconfirmed.
The Legend of Zelda
an amazing franchise requires a big pic isn't it?
Link
When you wear a bright green outfit yet are considered badass... you know you have succeded at being a video game hero.
Zelda
With Peach becoming a Sex symbol, Zelda could just stay behind, and unlike peach, Zelda has win all over her, wich adds flavor.
Ganondorf.
I've always sayd it... Ganondorf's is Nintendo's best villain ever, i can tottaly see him returning to brawl, with a revamped moveset, maybe even a sword?
I eagerly expect to see his update in the Dojo, with his new appareance.
Midna on Wolf Link.
Lvl. 40 dude. I can't really see a 4th Zelda rep that isn't midna, why? well i don't even know who this Vaati is and the other choice is skull kid... wich is lame, and Zant? pft. Zant has no chance of being a char in Brawl, of course... never say never, but i doubt it.
Besides, Midna would be pretty original.
