What do you think KatsuYamiYuu hero costumes would be like , if their were n Bnha universe ??
Personally, I like having parallels between fanon and canon, though I also like the thought of them remaining faithful to their original designs (like Deku and his jumpsuit)... More under the cut 'cause I know I'll be rambling though:
Much like Deku, Yami would welcome continuous modifications to his gears in order to expand his versatility. I can also see him replicating some OFA abilities in his gears as well (ie. grappling hooks for Blackwhip). I remember him staying Quirkless, so he'd also have other things to help him keep up with the others if not retain his utility in a variety of fields (mask & headpiece changed into a helmet with thermal/night vision; tranquilizers; traps; possibly some costume modifications for stealth; that kind of stuff). He'd unfortunately be on the heavier side in terms of the amount of support gears he'd be carrying compared to others, but I have a good feeling he'd find ways other than just strength/endurance training to keep himself compact and nimble on the field if he's as big of a nerd as Deku.
Proto!Kacchan/Gougou would prob have the least changes to his costume. One thing I found interesting in his attire/the way Horikoshi drew his design is the use of more loose/light, baggy pants, a sheathed knife and the posture he's drawn in:
To me, it gives the impression of him preferring more flexibility for martial arts/hand-to-hand combat purposes and him using his Quirk more so for an added oomph to his punches (I mean, look at the gauntlet and tell me it's not for making his punches literally explode in the enemy's face) as opposed to being solely reliant on his Quirk. Possibly overall more grounded (both in terms of Quirk usages & personality lmfao) than his canon counterpart, imo. I see him preferring his costume on the lighter, more compact side as opposed to, say, Kacchan's big ass gauntlets.
Yuu's costume would depend entirely on whether you view her more as Proto!Mt. Lady or Proto!Ochako---that is, aside from keeping her jumpsuit faithful to its original design (to parallel Deku as fellow MCs), how her gears would reflect her Quirk's usability.
If you feel Yuu would retain Mt. Lady's Gigantification Quirk, she would likely not have any support gears whatsoever to prevent complications that come with having them on her person (ie. breaking out of them when she changes size and/or figuring out a way for these gears to 'grow' with her). That'd mean the concept designs we saw of Proto!Ochako's gears shown in these images are nulled:
Rather than thinking of support gears, Yuu as Proto!Mt. Lady would likely lean more towards modifying her jumpsuit to be more durable and more resistant to external changes (more padding, tear-/thermal-/water-resistant fabric, more hardened material in like the fists/knees/legs for added combat damage). More 'layers' to the fabric would prob also mean she'd be prone to sweating underneath, though? probably? so I imagine the stomach sides in her jumpsuit from this image would be more light mesh (and unfortunately the weak spots of her costume outside of exposed skin):
One thing I feel that'd be different, though, is somehow implementing her mask to be more like heat-seeking goggles (or at least include some holographic overlay to provide it). This would help her immensely when trying to keep an eye on where all the lil' guys are at beneath her.
Now, if you instead see Yuu as Proto!Ochako like I do, I'm sure you can see from some previous sketches/drawings(?) that I personally believe she'd parallel Ochako's support gears with some of my headcanon-added components. More info of that can be found here.
