Smash 4 Highlight of the Day

Yeah, this was free, and it wasn't exactly a hard read or anything. Still, I was glad I got to pull off what I think is a combo; it isn't exactly easy to break out of. Also, this is a combo I completely made up, which as you can see is capable of KO'ing at incredibly low percents. Very effective but only viable if you can land that stun at just the right distance, and at just the right percent. Otherwise, if your distance is bad, you may either whiff on the nair or hit but will be unable to properly follow up with the grab after the down smash. Sometimes it's better to just grab right after the nair, but the down smash gives the damage that can make the succession of uairs into up b work. If you don't get the KO, but manage to pull follow up after the down smash, it's still a great way to create a pretty nasty conversion, or put you even further ahead of your opponent.

Again, only viable after a fully-charged stun blast. If you're a ZSS main drooling at the sight of this, do not attempt to do this just straight off of the nair (in other words, do not approach with nair). Your opponent will probably grab you.

Edit: This is in fact a true combo if you can frame-cancel the nair.

Edit 2: Probably goes without saying, but this is harder to pull off on lighter characters. I think it's actually impossible against Jigglypuff, and vaguely possible on Kirby. I haven't experimented much with Rosalina.

Edit 3: Well, aside from the down throw into double uair into up b. That's an obvious staple. But I did come up with sequencing it from nair after pondering whether it was viable to follow up with down smash after nair, and I quickly figured out that this can actually KO.
