Henshin a go-go Baby!
Ganon DownB beats them in priority and speed after the Dthrow. Nair might also work, but that's not a good option so meh. (Hell, you could even buffer an AD and get out like that, but you'd get punished for it.)☆ Say wha-- you tried to perform it and it didn't work?!? It should work, I tried that on nearly every character I play when I have Kirby, I couldn't be wrong... could I? ☆
You could in fact shield it and punish, BUT, that string is not a combo, and is, like everything else, only viable if A) The opponent doesn't know how to beat it, or B) you mindgamed them into it.
However, what kewkky said is spot on. I just mentioned how Ganon can do it, but others can get out of it too.
