All information I use is from the official smash bros brawl site so give them credit and hope they don't sew me.
Mario
With his familiar red cap, blue overalls and bushy mustache, the world-famous "Mr. Video Game" is about to set foot on the Smash Bros. stage for the third time.
An easy-to-use character, Mario sets the standard for balance.
He overwhelms opponents with magnificent jumping action!
Bowser
The biggest and the heaviest of fighters, Bowser has a slightly different flavor this time around!
To be honest, there are a LOT of characters that offer a slightly different flavor this time around. If you think they’re all going to be the same as they have been, it’ll be rough for you.
Samus
Her name is Samus Aran. She joins us from the Metroid games.
Look at her Power Suit shine!
Her arm cannon is equipped with a variety of weapons.
Mastering all of them is the first step toward victory.
Yoshi
Yoshi’s back and bursting with personality! He can launch consecutive attacks and even smack around enemies below him mid-flight.
Among other things, he can now use his up special move, the Egg Toss, to increase the distance of his jump. That’s enough to earn him a hearty welcome, isn’t it?
Wario
Many fans clamored for Wario to join the fray, and so now he finally makes his appearance...in his WarioWare costume.
It’s rumored that this unpredictable character will give birth to a form of martial arts that other characters cannot even see
Link
The hero of The Legend of Zelda series.
The design of this particular Link comes from The Legend of Zelda: Twilight Princess.
Link wields the Master Sword and a diverse arsenal of equipment.
Use all of his weapons to adapt to the ebb and flow of battle
Fox
Fox is just one of many so-called speed characters. His costume has been completely updated, so he’s full of fighting spirit.
Run! Fly! Move boldly! For such moves are the essence of Fox!
Zelda
Just like Link, Zelda’s design has also changed.
She has a slightly more subdued color scheme.
Her movement capabilities are not that good, but her magic adds power to her physical attacks. There’s a reason why her hands and feet glow, after all.
Donkey Kong
It’s Donkey Kong, ruler of the jungle. The original giant powerhouse makes a triumphant return!
Looks like his giant punch is still the haymaker you remember. Don’t doubt his strength or you’ll end up with the ultimate headache!
Kirby
This is Kirby, Warp Star-riding citizen of Dream Land who can suck up anything. His copy abilities allow him to steal the powers of other characters!
Yeah... He’s the only character who really hasn’t changed much from his appearance in Super Smash Bros. Melee. He’s round, pink, and soft.
Pikachu
With perfectly round cheeks and a jagged tail,
this can only be that most familiar of Pokémon, Pikachu!
It may be small and agile, but its electricity gives it powerful attacks.
It’s what you would call an all-around character.
Ike
From Fire Emblem, Ike appears! The fact that he can wield a two-handed sword with a single hand is a testament to his magnificent strength.
He brings his special move "Aether" with him as he crashes the Brawl party. Try for a single-stroke finishing blow with his mighty blade
Pit
The protagonist in Kid Icarus. Pit's Sacred Bow of Palutena is actually two blades combined. He can separate them or unite them at will for use in battle.
The arrows Pit's bow unleashes shoot out like beams of light. Players can control the curves of their trajectories.
zero suit samus
When Samus destroys her Power Suit, she’s left with the Zero Suit. What she’s lost in power and weaponry, she makes up for in speed!
Once she turns that Paralyzer in her hand into a whip, she has quite a long reach as well! Not exactly the straightforward fight you thought it was, huh?
