Idea
The Pun Tyrant
Again, incorrect. There are several logical restrictions of costumes and you even mentioned one of them. Besides, not only is there by law, but there is also by the sense of what being a hero is, and there are issues with the possibilites of said armor even existing.We've seen plenty of heroes in full armor, Iida and his family all wear full armor. They have never said anything about heroes not being allowed to wear armor. That isn't a rule anywhere. We've seen instances where the school limits usage of their costumes I.E. during the tourny arc. But Pro heroes can wear whatever costume they want. I mean hell, Midnight ran around basically nude when she first showed up. Costume restrictions are few and far between in BNHA.
I also dare you point out just 1 time when the Iida family's armor helped in the slightest in terms of protection, in fact. Those things are basically glorified paper mache.
Again, i don't have time to be arguing about this now, but here is a short summary of reasons why a power armor IC and OOC is a bad idea:
1. As a hero you are not certified to use everything- you are allowed to use your quirk but beyond that you don't get special licencing. Now, you could obtain this licencing, but it doesn't come by default. We know guns exist, and other weapons but they aren't used. This implies unless a hero needs a gun, they are not permitted one.
2. A hero is about a style unique to them in this world. That makes them markeatable , an essential aspect of their bread and butter. Inspiring hope is also an important task of beign a hero. both of these are hindered when the power you display is one made from machinery, things that could be used by anyone.
3. The technology of boku no hero is BELOW OUR OWN. Their technological progress basically stopped with the exception of a few gifted people.
4. There are regulations to costumes as we see in midnight not being allowed to actually go naked, but being forced to cover her skin. The armor worn by the majority of heroes is also usually innefective. Again, there are several implied laws.
5. Now getting to the OOC, such advanced technology would be a hugely unfair advantage AND break the point of the support course and the QEP/money systems.
