The problem with Skyward Sword is that she didn't do a severe amount to make her memorable in that game. Not any more than OOT. HW is a spin-off, so it's pretty irrelevant.
She rarely gets an actual story important plot. It's sad too, since this is part of why she isn't nearly as memorable as she could be, at least compared to the other recurring characters. Ganon(dorf), Link, Zelda, even many of the various races and monsters tend to be easier to remember.
It'd be neat if she got a DLC thing, though they could just add another Sheikah Champion, maybe the one who knew the Yiga clan members before they turned evil. In fact, that person could've been killed by them instead of Ganon. I don't know if you forgot, but the Champions all got killed in BOTW. That's why they were able to give their powers to Link. ...Are you fine with Impa being killed(who never dies in any Zelda game, possibly due to her ability to possibly shapeshift/change ages, etc...).
Agree with you there. Her roles haven't been exactly great outside of Skyward Sword, which is the game that brought her back and all. Ocarina of Time also stands out, as she's a Sage there, and one we also get to meet rather early and has a strong plot connection due to Zelda yet again. And in other recent games she is a Sage, just not very important overall like in ALBW. Breath of the Wild has Impa being implied as a very important character, especially in the past, but too much is left out in the open again.
I do have to say, that yes, if Impa where to be killed off in Breath of the Wild by a version of the Blight Ganons, I would take that over her current role. She would've stayed young in her design, the Sheikah would've had far more reason to remain so secluded as they do in BotW, and we had a Zelda newcomer now being all but confirmed.
But I get her old lady self is easier to work with, and a throwback to the first Zelda. I just now hope that the appearances of Young Impa can still continue, because it kinda sucks to have Old Impa take over now.
Agreed. Though maybe this is why the only two Sheikah are heroes, because they're the only surviving members of those who stayed good?
Am not sure, Impa was the only survivor in Ocarina of Time I remember, and in Skyward Sword, she was taken from the past where Hylia lived herself, and the Sheikah where still around then. Also a plot hole however, cause in Skyward Sword it's never adressed where the current generation of Sheikah live.
Weird how Breath of the Wild established the Sheikah race, but didn't really do all too much with them honestly.
