I checked and i havent seen anyone do this yet, but zss CAN go all the way under FD and get to the other side without falling to death
of course there probably wont be any use for this in battle but its a awesome show-off move
The timing is somewhat specific, but how its performed is you jump backwards off the ledge and do forward A air so you wont grab on to the ledge. while still holding forward once you get to about the middle of FD use her flip jump and after that jump again and you will be just in the range to grab on to the ledge
