Falcon- Only character to have two taunts for a single input (Down Taunt facing left or right)?
Actually, many characters actually have two taunts. You ever notice how some characters (like Wario) always face the screen when performing a taunt? They're turning right/left for those and thus technically have separate taunts, too. Falcon's is the only one that actually has a visual difference though, as well as frame difference. (Falcon's left dtaunt ends sooner, before the audio finishes, actually.)
So this is technically right and wrong. It may as well be right though. <<
Bowser- Only character who's dash is lower than their duck/crawl (yoshi?)
-Only character to shake the screen upon HeavyLanding (DeDeDe?)
Sadly, DK and DDD both also shake the screen on HeavyLanding. HOWEVER, Bowser is the only character who even has a screenshake on LightLanding!
Actually, to extend that, I'm looking at Bowser in PSA right now to check for the "Screenshake" parameter. Bowser has screenshake on... fsmash, usmash, dsmash, SideB landing, Down B landing, heavy landing, light landing, fallspecial(Up B) landing, nair landing, fair landing, bair landing, uair landing, dair landing, forward throw, back throw, down throw, up throw (multiple screenshakes), and DASH ATTACK.
For heaven's sake, Bowser has Screenshake on his DASH ATTACK. Bowser simply cannot land at any point without ever shaking the screen, even if it's a part of his attack animation. In fact, there is technically only one fighter in Brawl who has more screenshakes than Bowser. Would you like to know who it is? It's Giga Bowser, by a single animation. Bowser doesn't shake the screen while walking.
Pit- Only character with a side B that can be held out forever
I've heard SideB actually only lasts 10 seconds at the max.
Metaknight- Only character with transcendental properties on physical attacks
Actually, there are some other characters who have this. Lucario is the most notable. Aura has "transcendent" priority as well, but his hitboxes on his body can clank, so he's technically the only character with both "transcendent" and "regular" properties on all of his ground moves.
DeDeDe- Only character that requires an additional input to grab the ledge out of up-B
Actually, Peach can't grab the ledge backwards without pressing down to cancel the float, but this is generally true for ledgegrabbing from the front.
Fox- Only character who was "decloned" from their Melee counterpart's clone, so to say (New bair, while Falco kept the old one)
So true, so sad, lol. Technically it happened twice, too! Falco got Fox's old lasers from 64, as well, along with now having greater distance on Phantasm than Fox's Illusion, which is the opposite of Melee... (Fox had much better distance than Falco.)
Wolf- Only character that has a projectile attack that also functions as a physical one (Melee Ice Climbers could be spoken for as well)
Technically... Aura Sphere? Nah, I guess this is technically true... >>
Squirtle- Only character with water element hurtboxes (cause extra damage to Charizard)
*hitboxes
Sorry, this is just me being a grammar nazi. <<
Game and watch- Only character that can unstale moves without hitting anything (uair always acts to unstale no matter what)
Actually, this isn't true, but it probably might as well be. Game and Watch's uair is a regular hitbox with a wind parameter and 0 damage, like most wind attacks. It's just really big, so whenever it hits something, it refreshes your moves, and because of its absurd size, it usually hits something, so it refreshes your moves. It won't ALWAYS unstale your moves, as far as I know...
Kink-Link is smart. I like him. =D
You mean besides making the mortar go *thunk* *5 seconds later* *Boom!* fully charged as compared to *thunk* *1 second later* *boom!*?
Whoopsie, I read that as down smash.
Anyways, my contribution...
Bowser- Has by far the most screen shakes of any character (This superlative is big enough to be worth mentioning. ). See above for the full list.
Captain Falcon- The only character with a cinematic Final Smash. (Why hasn't this been mentioned?)
-The only character with an attack that can cause knockback, but will teleport the opponent back to their original location for a real attack, meaning Falcon is the only character with a true "Fake Attack." The first hit will send them to the cinematic scene, and the second hit will actually launch them. I don't believe the first "fake hit" will KO.
-The only character with his sort of SideB trigger. (I don't know how to explain it, but his SideB is definitely special. It'll even activate if it won't hit something)
Diddy Kong-The only character able to generate items with a non-Down Special input. (peanuts)
-The only character able to generate containers with all items off and set to none(peanuts hold healing peanuts)
-The only character able to generate healing items (peanuts)
Donkey Kong- The only character with a special completely devoted to a "quake" attack.
-The only character able to charge up a special facing one way, then release the attack in the opposite direction directly out of the charge.
Falco- Only character who speaks in full, complete sentences in all 3 taunts.
-Only character whose own attack can be "kicked" back to them.
Fox -Only character whose win-screen animation/phrases will change depending on more than one opponent (Falco and Wolf).
Game and Watch- only non-home run bat attack with the SCHREEEN sound that sends people sideways. (9 hammer. Rest and Shoryuken send straight up.)
Ganondorf - Only character who was coded wrong. Fair is supposed to autocancel faster than Nair, with the same IASA as Nair, allowing possibly FHFF Fairs to be lagless, and double jumps out of FHFair, but they used the wrong flag(Synchronous instead of Asynchronous), so now Fair has neither autocancel nor IASA. ._.
Ice Climbers- Only character whose tether recovery special works as a normal recovery special when not tethering the edge. (Melee Belay if it can't tether)
Ike- He looks like
Domon Kasshu from G Gundam in his
"soldier" alternate costume (last on the right.).
-His brawl appearance shouldn't be able to exist. He couldn't weild Ragnell in his "ranger" class (His brawl appearance), and wasn't able to use it until he upgraded to his [url=http://www.feplanet.net/media/sprites/9/character/body/ally/ike.png]"Lord" class. (which doesn't even have an alternate costume resembling it)
Jigglypuff- Only SSB64 veteran without any visual moveset alterations whatsoever since SSB64. (All her moves all have the same animations. Everyone else has had at least one move modified visually or replaced.)
King Dedede- Does not have an attack resembling his classic "hammer smash" animation of any of his Kirby games. In fact, his Fsmash doesn't even really resemble any attack he's ever had. (Can't think of anything, really)
Kirby- Only character unable to grab the ledge backwards during his up special (Has anyone said this?)
Link- Only character whose projectile has wind properties?
Lucario- Only character with a projectile out for a single frame, making it unreflectable.
More later.
