-Samus- Metroid fan since the 80's!
-Peach- Loved loved LOVED "Princess Toadstool" since Super Mario Bros 2
-Bowser- C'mon, he's awesome! Fan of King Koopa since Super Mario Bros 3
-Diddy Kong- Donkey Kong Country was the most graphically mindblowing game at the time for me, and Diddy kicked butt!
-Pit- KID ICARUS!!!!! Oooomg, such FOND memories of that cozy black background and the soft soft glow of the whites, blues, reds, and yellows coming off of my small 12" color tv in my room late at night before bedtime with the lights off. (same with Metroid)
-Kirby- Kirby Super Star is by far my favorite Kirby game, and one of my top Nintendo choices.
-MetaKnight- Because of Kirby Super Star.
-King Dedede- ...ditto
-Link- Again, a fan since day ONE in the 80s! Twilight Princess freaking rocks!!
-Zelda- This *IS* Zelda's legend, afterall!
-Red- Whether you chose "Red" or "Ash" as one of the default names when you first booted up Pokemon Red ("Blue" or "Gary" if you bought Pokemon Blue), or if you edited your own custom name, Pokemon Red/Blue was the game that started it all, and playing your three starters got my little fanboy heart fluttering...
-Pikachu- After playing the game and noticing the first episodes aired on TV, I noticed Pikachu, and I ended up like him in the cartoon.
As for Mario and Luigi, yeah, they're cool, but they just seem to be so "default" to me, like Ryu and Ken. I don't really gravitate towards them. They're cool, and I'll play as them once in a while, but they've never been my mains.
If TOAD gets in, you bet your face that I'll be all over that shroom!
If MEGA MAN gets in, I'll be charge-shooting my mega-buster all day long!
If GENO gets in, i'd probably die...

That's what so amazing about Brawl, the roster and the fact that they're reworking them from the ground up (to promote more balance? i guess?). It allows people to adopt MORE character to main.
Melee, i only used Samus, Zelda, Sheik, and Doc (occasionally Pikachu, Link, Ness, and Link). The other characters were too nerfed or useless for me to care enough to play them.
Brawl has characters that are ACTUALLY playable...I'm gonna have such an big list of Mains now!
