lmao todochako gala date or bnha prototype?? late twiyor Valentine’s Day????👍 gibberish! Wah!

Despite my lack of activity, I'm doing alright! Thanks for asking, anon!

Originally, Yuu's concept was that she was quite literally Mt. Lady, both in name and Quirk, with the only difference being in her design and a more timid/low self-esteem personality. At first, she was going to be the main protagonist, but Horikoshi changed his mind (something about her standing out too much?) and instead made her Quirkless friend, Yamikumo, go through some changes and become who we now know as our main protagonist, Deku. Rather than scrapping her completely, Horikoshi ended up splitting her into apparently 3 characters in the BnHA series:

Yu Takeyama/Mt. Lady, who inherited the name and Quirk

Ochako Uraraka, who inherited the 'female lead' role & overall design

And, surprisingly: Yui Kodai, who inherited the more 'quiet' aspect of Yuu's personality + some bits of her design from the conceptual process (and supposedly a part of her Quirk; I can't find evidence but it seems there's speculation that Yuu's Quirk not only changed her own size but the size of other things as well?)

Personally, because I like the idea of maintaining the Original Trio image (Yami as Deku and Gougou as, well, Kacchan) + feel that Mt. Lady rules that name/Quirk identity with an iron fist, I view Yuu more as Proto!Ochako and thus she keeps the Zero Gravity Quirk. If she were in canon, the easiest way I'd fit her in is to simply make her Ochako's twin. Because she's quieter and more level-headed (in my headcanon, at least), she would likely be a supporting role more so for Ochako as a voice of logical reason than for Deku. She'd also be more prone to downplaying herself compared to how much she paints her twin in a much brighter light. If you're into zodiac signs, then while Ochako displays the brighter sides of her Capricorn zodiac, Yuu would be the calmer & quieter sides (almost similarly to Todoroki, who is also a Capricorn). Also if you hurt her dear twin Ochako, she will not be afraid to drop a boulder on you.

Am I a little basic? Yes. Do I care? Not really!

These two are so cute together
