"Alright, Peach’s Final Smash seems to be misinterpreted as being a really bad. That is completely false. Peach’s Final Smash is really quite good, using it while your opponent is at low % seems to be a poor decision though, but peach can rack up damage with combos really quickly anyways. Peach’s Final Smash causes her to sing and dance which puts everyone on the screen to sleep. Oh wait, it puts everyone who is ON THE STAGE to sleep. It doesn’t put you to sleep if you are in the air, OR on the edge. So this one actually requires a setup to get against somebody who knows these things, seems like down throw into final smash would work, but maybe it wouldn’t because they could just stay and miss the tech, I’m not sure. There’s bound to be something though. Anyways, assuming that you just put everyone to sleep there are now peaches all over the stage that heal you quite a bit, you can easily heal up all of your percent if you manage to get them all, but it isn’t likely you’ll eat them all before you get your opponent. If you’ve used it at higher percents you can eat some peaches, then go kill your opponent with a forward smash (which got buffed quite a bit) then eat the rest of the peaches, it’s a really good final smash."
