Do you guys know that bair has like... this weird ledge teleport property? Like Pika's up-b and Wolf's side-b?
ZSS' second jump sweetspots the ledge but only at the very end of the animation. (Different characters sweetspot the ledge at different points during their second jump animations, for example I hear Wario's doesn't sweetspot it at all.)
If someone is standing above you trying to shield a uair from the ledge, you can drop down, second jump to about the where the ledge is, and bair and ZSS will like... bair, but then sort of teleport a centimeter towards the stage and just be standing on it as though nothing happened.
EDIT: made video. http://youtu.be/uS00sQu3q_Q Looks like the game wants to cancel ZSS' bair but can't without moving her legs into the stage, so it says "**** that" and just moves her there, very weird effect. It looks much more profound in 60 fps.
Yes I found this while trying to jump through the stage, I can't figure out how though.
Whoa I was just saying that with all the up-b nonsense we do at the ledge you'd have think someone would have at least done it by accident before now, so it must be a very specific part of the level.
