Bondo: 'If someone knew where to look'?
Midoriya: Uh... I'm a fanboy?
But what else... well, he was supposed to give suggestions, right? It felt kind of blasphemous to give suggestions to such a successful pro hero, but Izuku forced himself to look at it like it was any other quirk. The test hadn't actually specified that the quirk belonged to a pro, after all, so he couldn't let that hold back his analysis, not to mention that if he was accepted into the support course, he'd be giving pros suggestions for a living.
Mic: Don't forget pros are human too, so we all need to accept suggestions every once in a while.
So how could the quirk go beyond what Glimmer had used it for?
Well, she manipulated light energy, right? But... Izuku's eyes widened and he started writing the ideas as fast as he could structure them out. Not all light was visible, so what if she could manipulate not only the intensity of the lights but also the wavelength? From the footage he'd seen, some of the sparkles Glimmer had used had appeared colorful, especially that one time she'd produced rainbow sparkles during a pride parade, so it was definitely possible for her to shift the wavelength within the visible spectrum. And if she could do that much, she could probably train enough to create ultraviolet light and infrared light, which meant that she could use her quirk to burn rather than blind and maybe even use it like a black light to find forensic evidence at crime scenes!
Thirteen: Wow he figured that out fast...
In the end, Izuku's essay ended up being three pages long, two of which were entirely suggestions based on his theory that Glimmer could manipulate the wavelength of light.
Everyone: Three pages?!
Kurogiri: And that's only the first essay...
Bakugo: See what I mean?
It really made him wonder why she'd never used it that way. It would have effectively negated a lot of the drawbacks of her quirk, since she wouldn't have had to worry about blinding anyone if her light was invisible. It would also make her much more difficult to fight, since the threats wouldn't be as obvious. It was almost a shame that she had already retired, because Izuku would have loved to see if any of his theories were actually useful.
Hound Dog: Guess she never really thought about it.
Midoriya: But it's so obvious...
Uraraka: You're smart, Deku. Other people don't think outside the box like you do.
He didn't recognize the other quirk, so he didn't have the advantage of previous knowledge, but then again, he also didn't go into the analysis with any biases, so it all balanced out. It was some sort of jet quirk that allowed the user to blow air out of the bottoms of their feet, which would probably be most useful for speed or maybe even for flight, depending on how long the hero could keep continuously blowing air.
Midoriya; Gran Torino!
Gran Torino: Just out of curiosity, Nezu, did you actually use me as an example in the test?
Nezu: No, but do you want me to?
Gran Torino: ...I'll think about it.
They would need specialized shoes that protected their feet while still allowing the air to flow, and the rest of their costume might need extra ventilation as well, depending on where the air came from. It was probable that the quirk actually worked by taking air in through the skin to power the quirk, or maybe it was powered by the breath?
Midoriya: Gran Torino-
Gran Torino: Later.
If the hero could manipulate the temperature of the air, that opened a whole new field of opportunities. He could use hot air to make himself rise faster, or cool air to help victims during fire rescues! There were just so many possibilities, but Izuku limited those speculations to less than a page. He didn't know if temperature manipulation was actually within the limits of the quirk, so he didn't want to waste too much time on suggestions that might not actually be useful.
