This is the match up I've been waiting to analyze for the longest time. My entire defensive play style that I use on just about every character now evolved around me trying to beat my friends Peach.
Most Peach players will feel the need to poke around using their float, and like Praxis said, down air you to hell and back into an up air, up tilt at low percents. My solution to this is perfectly spaced forward airs. If she's floating at you, just jump back with her. Fighting peach is similar to fighting melee Marth in the sense that there is a bubble surrounding Peach that you don't want to enter if your playing on the ground. Back airs work well, and used defensively stuff just about everyone one of her moves. Personally, I save my back airs for edge guarding solely, but on some characters I need to abuse my priority to break one of their moves. Fortunately for us, Peach isn't one of those characters I find myself using them on for the purpose of beating one of her hit boxes out.
A good Peach player gets grabbed rarely, as most of the time she's aerial, only dropping to the ground when it's time to die. When you enter the 130's, most Peaches will start to FF forward airs at you in an attempt to kill. If you don't perfect shield the hit, you are usually not open for a free grab, as Peach's neutral A combo comes out pretty quickly and will beat out your attempt. Sadly, getting the grab is crucial as it is one of my favorite and main damage dealers in this match. Most chain grabs to the edge mean at least 20% guaranteed, and you need to put on that damage and kill her asap. Why asap? Well why not, you've got more matches ahead/better things to be doing.
From my experience, Peach's main kill moves are the Fair, perfectly tipped Up smash which kills in the early 100's, I think below 120, and the bomb/stitch face. Remember how you love using your side - B in hopes of getting that lucky Gordo kill? The feeling of satisfaction you get from that is unimaginable. Well, maybe I'm over exaggerating it just a tad, but the point of the story is, Peach has **** to throw back at you as well. Stitch faces do a good deal of damage, and travel fairly fast and can be glide tossed into. It's going to hurt if you get hit. Same applies to the bomb. I've never had a bomb glide tossed at me, but **** that would really suck now that I think about it. Pay attention to the faces on the turnips if you can, knowing what she has at her disposal can pay off.
As with most characters, you **** Peach off the stage simply put. Back air her as much as you please. You might want to lay off if she's below you though, I've found her Up B going through some of my attacks on various occasions. And don't just be cautious about the Up B, she can use any aerial while in float mode. Edge guarding peach is tricky. She can get that edge when she needs to, as well as bob and weave your attacks, so be careful.
In my opinion, this match up is 55:45 Peach's favor. She's just got combo potential at the wazoo on you during the early percents, and if it wasn't hard for her to kill you as most of her kill moves are telegraphed in advance, this match would be significantly harder. The importance of spacing in this match is of top priority.
Don't get hit.
Edit @ Gates:
Wow, I just realized I have multiple summaries on the first page. Woo hoo! But that's not what the edits for. I appreciate you putting up mine, but in contrast, I think it would be a good idea to put up a summary from an educated user of X character as well, that way they know what D3 users should be using, as well as X character.
Knowing is half the battle. /GIJOE!!!
