You know, with how strong gadgets and items are in this world, one could easily be a pro hero using just those
Just look at how crazy support girl's inventions all are, and other heroes who fly around on jetpacks, or the hero this ep with the huge digger thing, I mean, unless it's somehow their superpower, they're just relying on tech there
I wonder why deku never thought of or tried to go that route when he realized he didn't have powers
Just go through the top heroes list and copy all their most powerful equipment and stuff
Yayaorozu should just use her powers to create a bionic suit or something. She'd be the best tinker ever
Deku doesn't have the skills to actually build gadgets so he'd be relying on others to create it for him which during his previous school, he obviously didn't have access to it but we can assume he was hoping to go down that route since he still wanted to apply to UA. Interestingly, Deku was originally gonna be a batman type hero with the gadgets before the author was encouraged to go down the quirk route
Yayaorozu can only make things she's studied so its not like she can invent something completely original. She has to study everything down to the materials and elements things are made from so making the simplest of objects takes a lot of studying. Making a bionic suit would require an insane amount of knowledge on the subject, so for now she's not capable of making something like that. It's an interesting concept for the future though.
