Hate to triple post, but...
Dedede:
He is a heavy, slow, powerful character.
He has 4 mid-air jumps (5 total jumps).
His Waddle Dee throwing attack is weak.
His Up Special has good knockback.
His starting appearance is the Waddle Dee Shrine seen on the Dojo.
He has a pink costume.
He is a starter.
Appears as "Dedede" on character selection
People are under the impression that Dedede is not good. (This is only first impressions that are hours old, keep in mind)
King Dedede has the same voice as his anime counterpart. (Japanese voice. Not 4kids voice)
Waddle Dees are better than turnips in terms of knockback and damage. Dedede's Suction spits out fast, but not very far and has low damage.
More reports of Dedede being very slow with fast atacks, but a conflicting report of his Waddle Dees being useful and spammable.
Dedede Impressions: Attacks are fast, but hammer is sluggish. As stated before, his Up Special has good knockback, but is completely vertical, like Ike's.
Dedede's Suction is beastly because of it's force and strength.
Pokemon Trainer:
He is a starter.
Appears as "P. Trainer" on character selection
Pokemon Trainer disappears on certain stages. he was not present on Delfino Plaza.
Female Pokemon Trainer news is confirmed FALSE.
We also hear reports of black Charizard (unconfirmed)
UNCONFIRMED: Pokemon trainer's starting appearance is him running to a stop and taunting.
Charizard's has multiple jumps and his Fly is powerful. He flies straight up and burns anything around him.
His flamethrower is identical to Bowser's Fire Breath.
Squirtle's Water Gun is chargable.
Ivysaur is immobile while using Bullet Seed.
PT's Final Smash is very powerful.
Squirtle has fast attacks, but no reach.
Ivysaur is the more balanced of the Pokemon.
Charizard is heavy, slow-medium speed, and attacks using claws and tail mostly.
Pokemon trainer's starting Pokemon is random. So far, it's unconfirmed if the starter can be selectable like Shiek was for Zelda in Melee.
Takes about three seconds to change Pokemon.
Colors: Red, Green, Blue, and Black & White (original GB version).
PT's Pokemon do not have accessories like hats, glasses, ect.
Rumors of Black Charizard. Some suggest a very dark Charizard that is near-black.
Lots of Invincibility frames when switching Pokemon.
Ivysaur's jumps are quick, but short.
Squirtle's Side Special (Withdraw) is useful and quick, but easy to SD with.
Charizard is not good for FFA according to one person.
Kirby:
Final Cutter has been changed once again.
More confirmation of Kirby sucking up items.
One time during Kirby's FS, Starmen were launched from the pot. The enemies used the Starmen and ended up KO'ing Kirby.
Metaknight:
No strong attacks. He's the kind of character that relies on multiple hits.
FS is very strong and has a wide hitbox.
Not much use for gliding.
Taunt: Flaps his wings and does a "warp" or some sort.
People are under the impression that Meta Knight is very good. (This is only first impressions that are hours old, keep in mind)
Meta Knight is a good beginner character.
Link:
Link tried to FS an opponent who had a Starman and it failed.
Samus:
You can't turn into ZSamus at the start of the match at all.
Samus cannot missle cancel.
Peach:
Peach can float cancel.
Diddy Kong:
He's very fast and can 'put hurt on you'.
He has combo attacks, similar to Meta Knight.
Ike:
Victory Pose: "I only fight for those I protect" (May be off due to translation issues)
Ike is being called a noob killer. His Side Special charged can KO Kirby and Meta Knight at 35%. He is being called "too powerful".
Ike Impressions: Eruption has a lot of range and can be used in the air. His Final Smash has more range if you "charge it up"?
Donkey Kong:
DK's Final Smash used correctly can take up 90% of a stage. His FS was originally thought to be ineffective.
Unconfirmed Characters:
Ashley Deconfirmed! She appears in the WarioWare stage. So does 9-Volt and Jimmy.
Items:
Smash Balls can be turned off.
New Pokemon: Sheimi(strange, it's an event, it should still be hidden).
Dragoon was seen as an item.
Time Bombs and Spike Bombs are new items.
Muddy Mole is an AT(NOT Monty Mole).
Some people worry that the Smash Ball occurs too much.
Dragoon does 42% damage. It KO'd Mario at 0%.
The Beam sword is much longer than expected.
Stages:
Playable: Battlefield, Battleship Halbred, Norfair, Hyrule Temple, Onett, WarioWare, PictoChat, Bridge of Eldin, Delfino Plaza, Yoshi's Story, Smashville, Castle Seige, Pokemon Stadium 2, Skyworld, Lylat Cruise
PictoChat impressions: Some are negative, some are "better than expected."
Onett impressions: Virtually no changes made.
The PictoChat stage sometimes has impenetrable walls and can trap you on a side of the stage.
Attendee's Opinion: Pictochat music was bothering.
