Observations:
neutralB: Can be done in the air, slowfall during. That's mad good, means she can shoot you no matter how high up you are and cover options.
upB: Saw that combo on Clock Tower where she upB'd onto a platform, imagine the combo/reset potential she has doing stuff like this. upB them onto a platform, go into a grab or some other mixup, or if she CAN combo off that...damn.
Sideb: Not as good as I thought, if you don't land the first upB (witch twist #1 sends them far enough for sideb1 and sideb2 to connect properly) it doesn't combo properly off or into anything. Still, it's a movement option, though you can't edge cancel it as far as we can tell, the divekick version looks mad fast and great for recovery.
downB: Definitely has some vulnerability unless the players didn't try to dodge/shield after the flip ended, but man this counter is looking even crazier than we thought. If it lands they should never, ever survive, basically. And multi-downb looks crazy useful too.
nair: her equivalent of an approaching normal like ZSS nair, though it won't serve the purpose of a spacing fair like other chars have. Really low lag, might be her best bullet shot normal to use during a SH to provide Melee SH Fox laser-like damage.
fair: INSANE IMO. She can choose between one two or three hits, so shield pressure might be crazy on this. Hitbox looks tiny on each hit, but that's to compensate for having options during it. Pretty good. Will have to test the soft bullets on it.
bair: ZSS bair with less kb. Not much to say. Amazing normal, might be better than nair for SH soft bullet pressure.
uair: We saw in the newest official videos that Bayo CAN combo off upb into uair. Meaning upB...etc, etc, into uair at the top of the screen WILL WORK. ZSS UPB COMBOS #2 HERE WE COME! Aside from that, this thing seems to get even better when she shoots with it, but we don't know if further hitboxes are added on.
dair: Amazing. A stall and fall normal that sends down that ends HALFWAY into the duration that it normally does for others (ZSS, Sonic, Sheik). Meaning this move will actually be useful in many scenarios that those other ones aren't.
Again, want to emphasize that Bayo is bringing back Melee Fox laser pressure, but she can shoot in DIFFERENT ANGLES.
meaning she can do it across the stage, ABOVE her, or diagonally with uair (I believe, not sure on that one). That's pretty damn good.
