Introduction

With the ending of My Hero Academia finally being out, the series has reached its conclusion (besides any further movies that may be set to release in the coming years). The scaling has varied heavily over the years, where the scaling capped at building level and went to city, mountain and even reached multi-continental, with speed scaling having similar changes. However, with how we currently scale lasers in My Hero Academia, there is a tidbit of the verse that isn't addressed by our current scaling: the lasers.

Overview

In this CRT, I aim to address two specific instances of lasers in the plot: the X-66 Lasers (used by the American jets), and the "Can't Stop Twinkling" laser used by Armored All Might. There are other lasers in the series, but the vast majority of them automatically fail several of our requirements for light speed on this wiki. Thus, I intend to ONLY focus on these two for discussion. For background on each item, the X-66 lasers are technological-based lasers mounted on the American jets that fire beams, and All Might's laser is also a technological-based laser projector that was mounted on his motorcycle (in which, he even compares the laser to that of the X-66). I'll go ahead and explain why these lasers should be considered lightspeed.

Argument

For the sake of convenience, I'll list every relevant lightspeed requirement and how the requirements are fulfilled

  • The beam behaves in a reasonably realistic way, such as reflecting off non-magical mirrors or refracting and diffusing through liquids and materials.
All Might used optic resin to protect himself from the laser's heat, which is a real-life material that is used to refract, bend or sometimes absorb light depending on the use-case.
The kanji used in the chapter of All Might's laser title is "organic alternating current lamp" (有機交流電燈), and a lamp is an accepted real source of light on this wiki.

Also worth noting that the beams do not deal physical damage and only damage via heat, and the beams are intangible (All Might noted that only someone like Star and Stripe could make the beam solid).

According to our standards,
Additionally, if the characters that would scale to a light beam are already very close to light speed or even exceed it, there is less of a burden of proof regarding the light beam's validity.
There are multiple characters in the verse that fight using electromagnetic radiation (Shigaraki, All For One), and the currently accepted speed of top tiers is 0.62c, or 62% of the speed of light. Thus, it's much more reasonable that the beams would be lightspeed.

Additions

Some may be wondering about how sturdy the actual logic is when it comes to assuming that the X-66 and the Armored AM lasers are similar to argue as lightspeed. While it is a bit of an assumption, All Might's suit was designed by Melissa Shield, an American scientist. While absurd amounts of wealth went into building the suit, it's unreasonable to assume that the tech built by a private scientist would surpass that of the United States' military. All Might, again, also compares his predicament with that of Star and Stripes, leading it to possibly link to the lasers being similar. However, in case this isn't agreed upon by everyone, I'll set three options here.


Option 1: Both Lasers Accepted as Lightspeed

Option 2: All Might's Laser is Accepted, Not X-66


Option 3: Neither are Accepted

I also really don't want this discussion to devolve into scaling, so if people could not mention that in this thread it'd be greatly appreciated.
 
I agree with this. Some additional evidence is the X-66’s laser cannon being portrayed as a lens in the anime.

This also appears to be the case in the manga as well.

Edit: for reference, here is the laser turret on the real life Boeing YAL-1 aircraft

"i find it funny how humanity is in the year 2026, can make mountain level nukes, particle accelerators and an artificial sun but we can't make FTL spacecraft or lightsabers"
FTL under normal circumstances is physics breaking as things are without some capacity to manipulate space, not remotely the same as saying they don't even have legitimate laser technology


Same goes for light sabers, thats basically just magic

it was a joke, if you couldn't tell

I mostly agree but i did want to mention that we do see it destroy the ground on contact with force and not via making it explode/melting it

Did not pick up on this the first time I read, thanks

Though according to our standards:
  • The beam primarily deals damage by means other than heating materials that absorb it.
    • A laser may cause explosions, but only if it rapidly vaporizes some matter, meaning that the target needs to be partially destroyed in the process.
The word “primarily” is key; also it’s not impossible that the beam causes explosions, we aren’t able to see AFO as he’s being lasered and he has Mid-High regen, so he’d be able to withstand being vaporized anyways
 
To my knowledge we have enough moderator votes?

Is there anything else needed, or can we close

A follow-up thread will be made about scaling and whatnot
 
If any added arguments helps for the X-66. here’s one I heard a while back.

“Star activated her quirk by saying Laser. New Order only activates if Star says the correct name for what or who ever she is touching. Laser is specifically an acronym for Light Amplification by simulated emission of radiation. If these lasers were not actually photonic then they would not be lasers and as such new order would not activate upon her saying laser”

The only ever follow up thread would just the implementation of future laser calcs, such as that potential ftl all might laser dodge calc (hasn’t been evaluated yet but was made by Rusty)

The scale chain stays the same exact way as the radio wave scale.
 
You only have 2, therefir and random sadly don't count as they are only content mods

Im pretty sure on inanimate things she just needs to call them what she considers them to be and nothing else
