Anyone mess around with f-throw -> dash attack? It seemed kinda dumb when I was thinking about it, but I notice a lot of people hold away after getting thrown by ICs. This can let Nana hit fast fallers with a dash attack, and depending on the timing, can send the opponent away (kinda pointless), straight up (pretty good), and back towards you (looks cool, but really only useful for messing around). At lower percents, the timing is more strict on the dash attack to get a good angle since the thrown character doesn't travel very far, making the window to get a good hit fairly tight, but if the opponent holds away, the window gets a little bit larger.
I figured that the only practical use of this would be off a low percent (0%ish) dash grab against Falco or Falcon (since up-throw follow ups are probably more consistent on Fox) or as a mixup against opponents who hold away off of being thrown. I think some of the better follow ups off of this would be to wave dash in and regrab if the opponent is sent straight up, especially if this puts you in range to perform the chain grab at the ledge. If they are sent towards you it's possible to regrab, but there aren't many follow ups that occur after that since Nana is pretty far away. I guess just smash attacking them would be pretty okay.
Here's a really crappy video of me doing this a few times so you don't just have to visualize what I'm talking about :

I've only messed around with this for a few minutes today, so it might be totally pointless/bad to go for this, but I figured it might be worth experimenting with, especially for the more "
adventurous" ICs. I'm sure this works at lower percents, but I haven't really checked when it's escapable by double jumping, but it's also worth noting that you can get all of the possible trajectories off dash attack at any percent if they connect.
