Nintendo has yet to put a minor character from any game in. That's why. Let's take a look at all the characters released in any smash game so far. Every single one of them was major in some way. Sorry guys, but a character who played a tiny part in a small game isn't going to have much of a chance of getting in.
Bowser - One of Mario's main enemies. Appears in nearly every Mario game.Duh
Captain Falcon - One of the first unlockables in F-Zero games, main character of TV show. He was one of the original 4 racers.
Diddy Kong - Star character in many DK games. Plays a big part in storylines. I'll give you that...
Donkey Kong - Main character of DK games. OK...
Dr. Mario - Dr. Mario series of games, this character was a last-minute clone.Meh
Falco - Consistent character in Star Fox games, this character was a last-minute clone.Sakurai remarked on how he liked having Falco in Melee. He's more than consistent, he's Fox's Luigi, and one that doesn't get thrown aside that much. Sure, he leaves the team a lot, but still....
Fox - Main character of the Star Fox games. Yeah...
Ganondorf - Main enemy of Link in Zelda games, this character was a last-minute clone.Was intended as a full character at a stage of development, though.
Ice Climbers - Star characters of classic "Ice Climber" Nintendo games. More like, Nintendo GAME.
Ike - Star character (I think) in Fire Emblem games. Only appears in 2 out of 10, you can't just say "Fire Emblem games" and get away with it. At LEAST go to wikipedia, you nimwit.
Jigglypuff - Nintendo uses Jigglypuff a lot (popular character in Pokemon series). Second to Pika in Japan, yeah.
King Dedede - One of Kirby's main enemies. I'll give you that.
Kirby - Main character of "Kirby's Dreamland" series. OK...
Link - Main character of "Legend of Zelda" series. Uh huh...
Lucas - Main character in newer "Earthbound" games. He only starred in Mother 3...
Luigi - Main character in many Mario games. Yeah...
Mario - No **** sherlock For real, Watson.
Marth - Lead character in Fire Emblem Games (I think). Fire Emblem 1 and 3. If you're gonna make a thread like this at least look it up so you don't use things like "I think" and etc, which make you seem like you're full of it.
Meta Knight - Another one of Kirby's main enemies, appears in most Kirby games. Yeah.
Mewtwo - Hardest pokemon to get in early games, lead villain in many movies/TV show. Master Ball FTW. He was just there... only really a villain in the anime.
Mr. Game & Watch - Classic nintendo character, star of the "Game and Watch arcade" series. He wasn't named until Melee, but I'll be nice.
Ness - Star of early "Earthbound" games. Only Mother 2.
Peach - Consistent lead character in "Mario" series. Yeah, the girl in the other castle.
Pichu - Cute little guy, this pokemon was a last minute clone that took 10 seconds to make. Eh, it took like one third of the time of a character to make, not exactly 10 seconds, but I'll just think you were doing a hyperbole.
Pikachu - One of the main characters on the TV show, in Pokemon yellow version. Yeah.
Pit - Main character of whatever series it is he's in. Things like this make me go "idiot... *rolleyes*" You could at least go to ****ing wikipedia to check it up, let alone other thousands of videogames sites, but NO, you just HAVE to be an ignorant ****.
Pokémon Trainer - Main character in every pokemon game. Not every. This Trainer has been in R/B/Y/G/S/C/FR/LG but, yeah...
Roy - See Marth Only a main character of FE 6.
Samus - Main character of Metroid series. Yeah.
Sheik - Goes along with "Zelda" character. Ok... though we don't know if she's in Brawl yet.
Snake - Main character of "Metal Gear Solid" series. Yeah.
Sonic - Main character of "Sonic the Hedgehog" series. Uh huh...
Wario - Main character of "Wario" series. I'll give you that.
Yoshi - Consistent character in Mario games. Yeah, and the Yoshi series too.
Young Link - Cute little guy, this boy was a last minute clone that took 10 seconds to make. *sigh* I'll give you this one.
Zelda - Important character in almost every "Legend of Zelda" game. Yeah.
Zero Suit Samus - See shiek, goes along with "Samus" character. ...ok...
Now let's look at some requests.
Midna (Twilight Princess) - played a medium role in ONE "Zelda" game. Not a very good chance of getting in. Not any better than any other medium zelda character (The Wind Fish, for example) MEDIUM ROLE?!? She was a main character. As important as Link. More important than Zelda in that game, even. A title character. Idiot.
Captain Olimar - very good chance of getting in. Star character of new nintendo series "Pikmin". At least you're not a puppy killer.
Geno - minor character in Super Mario RPG, has showed up as a minor NPC in other games. Low chance of getting in. I'd put him up there with, say, "Tarin the cucco farmer" from the Zelda games. MAJOR character in SMRPG.
Star Wolf - minor enemy of Fox in early Star Fox games. Showed up as a minor character in Assault as well. Medium chance of getting in, only since there aren't many SF games. No. He rivals Fox. Not a minor enemy at all, actually.
Skull Kid - Extremely minor character in Zelda Oot, played a slightly larger role in MM, hasn't been seen since. Chance of getting in: Next to none. He was seen in a new form in TP. Yes, he did have a minor role in OoT but his role in MM was MAJOR, not "slightly larger".
Captain K. Rool - Major enemy of Donkey Kong. Stands a good chance of getting in. However, in the SSE video it showed a koopa stealing DK's bananas which slightly diminishes the chances of K.Rool's appearance, but we'll have to see. Shut up. Due to the crossover nature of the SSE K. Rool could be attacking DK later on, or not at all. He could shoe up to attack, say, MetaKnight.
Knuckles - Playable character in some Sonic games. Medium chance but Tails has a better chance of making it in. As better as Tails's chances might be, they're both a stretch.
Isaac - Major character in Golden Sun series. Hopefully Sakurai will remember to put him in, I'll be surprised if he's left out. Yeah.
Krystal - major character in more recent Star Fox games. Good chance of replacing Falco. Because we can't POSSIBLY have 3 Star Fox reps, right? That was sarcasm, idiot.
Tingle - minor character in a few Zelda games. No chance of getting into Brawl whatsoever. Tingle has 2 games, in those games he's the main character. I don't want him in Brawl though.
