I don't care if some people have posted disjointed tidbits about Peach before, this will be a thread which will discuss all of the changes made to Peach in Brawl.
A companion thread would be the one with the video (I made) of Peach's moveset in order to visualize the changes, though I forgot to do the Bair while not floating and Bthrow. I'll fix that come Thursday).
Jab - It now launches the opponent even at low percentages (although it doesn't launch them that high). As crouch canceling is now out, you no longer have to fear them CC:ing her jab and punishing her.
U-tilt - Is just as fast as the old U-tilt, is a great anti-air. However, the Hitbox is mostly in her upper arm and above, so it will whiff on short standing foes (like Kirby, Meta-Knight, possibly Pit, etc.). It's quite strong, but not as strong as Upsmash. The range and priority is kinda better (in Melee, her head was invincible).
D-tilt - Faster, but since Dash Canceling is out and her D-tilt doesn't really have that great a range nor is it as fast as a lot of other D-tilts, it's virtually useless now (you can't dash cancel into a D-tilt, you have to somehow get close enough for it to hit or bait them into running into it).
Dash Attack - Two hit combo. First hit has little knockback and will knock them into the 2nd hit. Easy to DI because of this. Not a guaranteed combo-starter even without DI. Will knock them too far away once they hit the 30-40%-mark.
Dsmash - Nerfed into infinity. No CC, so the opponent can't CC it to receive the full damage at any percent. A full direct hit will inflict, like, 21% at most. Has virtually no knockback (will not KO in Sudden Death), has a reduced hitbox. The only "Good" change is that she now crouches lower when she does it, so high attacks will miss >_>'.
Fsmash - All three fsmashes have been buffed. Will kill at lower %s, especially the Frying Pan which is still mostly a vertical KO:er. Still not nearly as strong as to be considered "strong KO-moves".
Nair - Reduced priority, length and range.
Fair - Faster on both startup and cool-down. Still not as fast as most Fairs (Sheik, Marth, Fox, Falco, pretty much anyone else in the game).
Upair - I believe it's slightly stronger, the motion is also bigger and it reaches further up from Peach's body than in Melee (she kicks higher).
Bair - Two hits (undiable). Bair will make Peach move a great distance behind her, extending it a lot backwards now. Virtually no lag on landing.
Dair - Nerfed. I believe it's got a little bit higher priority and hitbox. However, the last hit launches and it launches them quite a lot so unless they only have 20% or less after the dair hits, you cannot combo from it. This coupled with the nerfed second jump greatly diminishes the use of dair.
Up B - Extends further away from her body now. However, fastfalling it will cause her to still fall quite slowly. Will have a landing lag animation even if you fastfall it. Auto-sweetspots if below the edge and close enough. Can KO now.
Peach Bomber - Makes her fly forward a greater distance. Will sometimes semi-spike (though the knockback is too small to actually make a difference), faster on startup and cooldown. She'll bounce her upwards now from a hit, but only if it hits a person or Sandbag. Will not bounce off of walls.
Toad - Faster on startup and cooldown. Still too slow. Can KO now (knockback no longer set).
Double Jump - It's so nerfed it's practically inexistent. She gains less vertical distance than Toad is tall.
F-throw - Illogically nerfed. It required 150-170% to KO in Melee. Now it requires much more.
Bthrow - Nerfed. Less knockback. I think the opponent faces away from Peach after being launched away, but this doesn't actually matter since you can now grab the ledge even with your back turned to it.
Uthrow - Too much knockback to combo or chaingrab off of it. To little knockback to KO.
Dthrow - Not that comboable. Especially not at anything above 60%.
Dashing - She dashes faster now.
Item tossing has been nerfed - The distance she can throw items (including turnips) now has been nerfed greatly.
Beam-sword (hers) has been nerfed - No range on anything.
Stichface - Greatly diminished knockback.
Bob-Ombs - Nerfed. Diminished knockback.
~~~ No Float canceling ~~~
Please tell me if I forgot anything and I will add it.
