i'm just joking with you
I can't say for certain, haven't gotten a chance to do much with it yet.How reliable is Greninja's Dthrow->Fair with DI? I take DI into account when considering throw combos, especially when the throws are slow or predictable enough that you should be able to DI then properly every time. Greninja's throws are fast enough, but Kirby's throws, besides maybe Bthrow, are all very long animations in comparison to most throws, so you should have proper DI every time. That's why I don't even consider Fthrow to be a combo at high/kill percents, even with Upper Cutter, because DI away sends them too far.
Then there's Luigi's Dthrow->Cyclone, which gives enough hitstun for him to follow regardless of DI
I did manage to land it twice today when I actually remember it existed but I'm pretty sure I wasn't in the true combo % range yet and my opponents just fell for it because they probably didn't know it was a thing lol
There's one thing about it though.
The best way to DI Greninja's Up-Throw so you don't get killed by it is towards him (Mario lives very slightly longer, as in, 4% longer if he DIs towards him, any other direction gets him killed at 164% with no rage, Bowser survives 8% longer in comparison)
The best way to DI Greninja's D-Throw so you don't get hit by F-Air is away from him.
You said it yourself that Greninja's throws also have a fast animation and thanks to D-Throw -> F-Air being a true combo close to %s where Up-Throw start killing and rage makes telling when it kills all the harder. Greninja basically forces you to guess which throw he's going to use unless you react pretty quickly to it.
You don't get killed earlier if you DI away from Greninja if he uses Up-Throw, so that's probably the most optimal choice, but hey, if you can survive just one more Up-Throw if you DI towards him, you probably will want to do it, especially if it's your last stock. Then he D-Throws instead and you get hit by F-Air and dies.
That could be a pretty mean mix-up I think.
