#also if there's any inaccuracies with how prosthetics work/wrong terms used for prosthetics pls let me know! i dont intend any disrespect!

idk if your still busy so obviously finish what your doing before doing anything else but do you know how hyuna's prosthetic latches together?? I think theres like a knee-latch on her prosthetic that's a bit father down than her other leg but theres so much going of its hard to tell whats going in that area

Honestly I'm not sure how the mechanics of it would work, especially since there's got to be some weird alien technology or structure at play there. It's pretty different from what a prosthetic leg is like in real life, so it's tricky to make assumptions based on that, too.

There's some stuff I noticed about Hyuna's leg across the various official arts, though. Mostly the fact that it's inconsistent, and I kind of see a reason for it. Please forgive me as I go on a bit of a ramble.

In her original performance outfit the prosthetic is structured almost like it's just a normal leg molded out of metal. It's a lot more solid and is dark in color, almost black. It also seems as if it goes up to just her knee? Maybe it still goes up to her thigh and she just ripped her pants until the knee for better/unobstructed joint movement. It joins at the ball of her knee and seems to be composed of quite a few different parts, somewhat complicated.

In All-In, Hyuna's prosthetic is still mostly of average leg shape. The most notable difference is that the leg includes hollow spaces, most likely thinner parts assembled together as opposed to one solid leg. It's also a different, lighter color. We can infer from this image that her leg is until her upper thigh.

And then we have the latest one. Hyuna's leg in All-In seems to be until her upper thigh, but this image makes it seem as if it goes much higher than that (although it's most likely an artistic choice. maybe I shouldn't look into it too much. I've learned my lesson 😭). But it's interesting how this leg is the most unique, solid and without hollow spaces, but considerably thinner, more simple.

There's also the fact that you mentioned, the latch being farther down in comparison to her actual knee. It's different from her previous prosthetic legs which seem to join at the knee exactly and are much more similar to that of normal leg anatomy. For this prosthetic, her leg doesn't actually latch at the knee, it latches just a bit below it. The prosthetic knee may look a little lower, but it's just the way she's angled, left leg facing left and right leg facing forward.

Maybe I'm overexplaining something that's already obvious/basic knowledge, my bad. Also I'm no scientist, so I could be wrong.

Anyway, the fact that Hyuna's leg changes quite a bit is interesting. It could be a design shift from the earlier production of ALNST to the finalized version, but I personally like to think that Hyuna's leg changes because she replaces it sometimes. Her lifestyle calls for a lot of action, and while her body can heal itself overtime, her prosthetic leg is prone to wearing and breaking apart.

This is how I see it (just a theory/maybe headcanon):

The leg she has in her performance outfit is one supplied to her by the aliens, which is why it looks much more sturdy, more like a true human leg. They're very advanced, so they'd know exactly how to make one that best suits her. Once Hyuna escapes to the rebellion, she doesn't have access to that kind of material anymore, nor does she know how replicate it. So instead she gets creative, taking scraps of metal and joining them together to make another leg, which is why it looks considerably lighter and less complicated. Whenever her leg breaks, she (or someone from the rebellion) creates a new leg from the material they can find, which is why her legs become progressively more simple and less conventionally "leg-like" . It's no problem to her though, and she's very proud of it.
