Bnha rant #15

Hi hi everyone!! I return with once again another thing about someone's quirk! Today? Bakugou Katsuki (I wanna say here at the top that I don't particularly like Bakugou so if there is any biasness or passive aggression in this that's why!)

Bakugou has excellent control over his quirk. This is stated in cannon however I don't think its ever expressed to the extent that it is.

His quirk (explosion) allows him to excrete a nitroglycerin-like sweat, which is all good and well except for the fact that nitroglycerin is a unstable explosive in its pure form.

Granted, the substance is only like nitroglycerin but it could still be unstable, meaning that Bakugou has to know how to move without causing explosions. Nitroglycerin goes off with a small jolt of movement so if Bakugou makes one wrong move it's likely something will explode. But, that never happens in cannon, likely meaning that Bakugou has such good control over his quirk that he can do drastic movements (as show below)

In addition to that, he is able to control when an explosion goes off. Which is another example of his control over his quirk.

TLDR: Bakugou has one of the most unstable quirks in class 1-A yet he has excellent control over it.

(p.s. do you like the new layout?)

Bnha rant #14

Hello hello!! Today I bring you more quirk questions :9 The victim? Mezo Shoji!

Analysis/questions start here

I'm sure we are all aware of how Shoji can recreate ears, eyes and, mouths on his limbs right. But the question is, how? He creates some of the most complicated parts of the human body within a matter of seconds on his limbs?? what does even look like internally??

I'll start with the ears first: So, if you didn't know I'll insert a diagram of how we hear things! The questions will be continued under that :)

How does he create all of that within a matter of seconds AND have it work properly? I'll start with the how! What does he make it out of? Is it similar to how Eri can rewind stuff but not make matter up so if you want her to give you your eyes back you'll either have to get a set of eyes to use or have her use a similar organ in the human body? id send it to your brain and then BAM! you're seeing things!

Now with that out of the way I'll get into how this relates to Shoji !

How does he create all of that within a matter of seconds AND have it work properly? Does shoji just make matter or does he sacrifice a part of his body for the extra appendages? Or does he just have extra stuff stored somewhere in his body to create them? Also! Where is it located?

Does the ear canal just follow along his arms like below?

Now onto the eyes! For his hand eyes (what else am I meant to call them?) do they even work properly? Or do they see in black and white? because I would imagine that its rather difficult to create all the complex internals of an eye (the cones, rods and other small details) within a matter of seconds. In addition to all of the, how does he see out of them? its the same issue with the ears, the distance from the ends of the appendages to his brain is so vast that I feel like it wouldn't make sense. Do the receptors that allow us to see just follow along the same lines as the ear canal?

Finally the mouth! After the mouth there will be one more statement with my final thoughts and then the traditional tldr statement :) HOW DOES HE MAKE A MOUTH??? AND GET IT TO SPEAK???? Do his lungs just suddenly connect to this random new mouth or does he make a whole new set of lungs just for the new mouth?? also! if he kept a mouth long enough would it lose teeth, or are the mouths just a replica of his own? So like, if he had dental issues would the mouths also have the same issues or are the mouths like brand new with baby teeth?

Final statement Basically, all I wanna know is the exact process that happens when he makes these new appendages? where do they come from? does he have to sacrifice things already existing in his body to make them? and do they work well?

TLDR: Shojis quirk makes 0 fucking sense, how does one man make so many complex parts of the human body in a few seconds (followed by a mass amount of questions)

Bnha rant #13

HELLO EVERYONE!! I'm back!! I descended into the madness that is ao3; But I have returned! The rant is going to be less structured and is going to present how I'll most likely be formatting my quirk rants in the future :) The old format may have been more professional and organized but it was so draining and made me lose all interest so now were doing it this way!! Todays subject? Ochaco Uraraka ^^

analysis starts here

For starters I wanna say, calling her quirk "Zero Gravity" is an injustice. I would say a much better name for it would be something similar to "gravity negation".

To give evidence for this: I'll start with the first time we see her use her quirk (when she saved Midoriya from falling on the first day). If her quirk really was "Zero Gravity" Midoriya would have just kept going up into space due to not having any gravitation poll. BUT THATS NOT WHAT HAPPENS! What does end up happening is that [Midoriya] just sorta floats there. Implying -however indirectly- that Urarakas' quirk isn't "Zero Gravity" but instead allows her to lessen the gravity of things (that could also be a pun for her having a bubbly personality and lighting the mood of a situation, therefore making the gravity or intensity of something lighter).

For more evidence lets look at the sports festival. During her fight with Bakugou she, for a short period of time, floats her jacket low to the ground to distract Bakugou. Same as before, if her quirk was actually "Zero Gravity" the jacket would have just kept going up.

Once again during the sports festival, when she used her quirk to float boulders above Bakugou to pelt him with. Its the exact same as before, If her quick was "Zero Gravity" they would have just kept going up.

NOW FOR A FUN LITTLE TIBIT

Seeing as her quirk isn't actually "Zero gravity" but is instead, her negating the gravity of objects, it's very possible she could increase the gravity of an object or person allowing her much more offensive options.

TLDR: Calling Urarakas' quirk "Zero gravity" is an injustice and it actually should be something along the lines of "Gravity Negation" due to lots of evidence

Bnha rant #12

Todays quirk analysis is on Momo!

Analysis following canon starts here <3

Creation is a quirk that allows Momo to materialize/create (as the name implies) different non-living objects as long as she understands the atomic configuration of the object. She creates things by breaking down her body fat at a molecular level, which will then be re-used as material for her to shape into objects with her quirk.

The process that she has to go through to create things are:

-imagining the parts

-imagine the materials

-imagine the assembling process

-finally, imagining the coating

Momo can also change the materials of the objects she makes to give them special properties. She can also only half-way produce something, leaving it to protrude from her body.

Strengths

Momos quirk is very versatile and allows her to both be on the defense and offense. She also has one of the best quirks for working with a team, allowing her to produce things to help her teammates as a whole and individually.

Due to Momos high intelligence and quick thinking she is able to create plans almost any challenge she faces.

Weaknesses

Momo requires time to make things and so if she is continually attacked by her opponent she has no time to think and go on the offense.

What Momo makes depends on both the complexity and size of the object as well as the amount of fat lipids in her body. The more complex of an object, the more complex the item is, the more fat lipids she expends.

Momo ends up weakened if she doesn't have enough fat stored up to create things.

In order to create things she must understand it at an atomic level and so she isn't able to create things she doesn't understand at an atomic level.

Special moves

Yaoyorozu's Lucky Bag: Creating a cannon, Momo makes and shoots a bag that is filled with tools for her allies to use.

All the info above can be found on Momos wiki page :)

Questions

What is the biggest item Momo has ever created? The most complex item she has ever made? Does her body type change when she uses her quirk and does that cause her to have to constantly have clothing in all sizes?

Analysis following my own theory starts here !!

My personal theory is that her quirk is actually just an advanced metabolism. The way she trains her quirk in canon is much more aligned with the metabolism idea. During the training camp arch she continually eats while making things. After eating things they don't turn directly into fat lipids, making it much more likely she's using the energy from the food than the fat lipids.

There is also no noticeable change in her body type when using her quirk. I would think that expending your fat lipids to create things would make a change in your body type, so the lack of a body type change makes me think that her quirk is an advanced metabolism.

All of the theories above would allow her to make a drastic change in her hero costume, because she wouldn't need as large of a space create things. I'll probably touch on that during another rant, maybe during the support item saga :v

TLDR: A quick summary of Momos quirk and her special moves, as well as how I think her quirk would actually work.

Bnha rant #11

Time for some quirk analysis!! I'm very excited to share these so you can expect them to be very long :)

Today? Mina Ashido or Pinky <3

Here starts the analysis following canon

Mina produces a corrosive liquid from her skin, her skin is resistant to said acid. Her pink skin is a result of her quirk altering her skin pigment but, unlike her skin the acid is a grey color.

Mina is able to produce high amounts of acid from her skin and is able to control its form to an extent. She can also control the levels of the levels of solubility and viscosity of her acid.

Strengths

Mina is able to produce enough acid to melt solid objects, including metal. She is able to control the level of acidity and viscosity of the acid making her quirk extremely versatile. She is also able to use her acid to make entrance and exit holes into buildings.

Along with that she can use her ability to burn holes into things to climb buildings and walls. She is also excellent at mobility, producing acid under her feet and using it to skate around.

Weaknesses

Mina's skin isn't 100% acid proof so if she produces too much acid her skin will start to wear away. She also has difficulty controlling the he levels of solubility and viscosity of her acid, which makes her wary of fighting people. Her quirk also doesn't have any strength enhancing properties, making her a bit more reliant on her quirk.

Special moves

-Acid Veil: Mina maximizes her acid's solubility and viscosity and creates a powerful acid wall which blocks incoming projectiles. (Its powerful enough to break the balls in the provisional license exam, which are harder then concrete)

-Acid shot: Mina launches a barrage of acid bullets on an opponent and their surroundings

-Acid Layback: Mina produces acid from her feet to dissolve the surface of the ground, allowing her to spin faster. With the added speed she is able to throw projectiles at a higher speed

Grape-Pinky Combo Mineta-Bounce: The follow up for Acid layback; After using acid layback Mina throws Mineta and he throws Pop-off spheres and bounces off them

-Acidman (My personal favorite <3): Increasing the viscosity of her acid, she produces a large amount in a vaguely anthropomorphic form, covering her whole body. This move is also defensive and will dissolve an attack launched at Mina

All of the info above can be found on Minas Wikipedia page ^^

Questions

Where does Mina produce the acid from? Its obviously from her skin but is it from her pores? Or does she have two sets of pores, one for the acid and one for sebum (the stuff your pores normally produce)? Is her acid just a different version of sebum that she is able to control? (After the questions there will be a section on more detail about sebum and how it relates to Minas quirk) Where does the acid come from? Does she have a place to store the acid underneath her skin? Where does the acid come from? Is it in her blood stream?

Analysis following my own theory starts here!

Sebum is what your pores produce and, it is acidic. It has a pH level of 4 to 5.5 (anything below 7 is acidic). So this begs the question, is Minas quirk just her controlling the sebum she produces? The pores that produce sebum don't exist on palms and bottoms of the feet (places we see Mina produce acid from several times) so Mina would need to have extra pores on these spots.

Assuming Minas quirk is just her controlling the sebum she produces its more then likely she would also have the needed pores to produce sebum on her palms and the bottoms of her feet. Minas quirk changes the color of her skin to be a pinkish purple, so if we stick with the idea that her quirk, rather than it being 'producing acid from the skin' and being 'manipulating the sebum she produces naturally', it could be the natural coat of sebum on her skin that has caused this change. Though that is highly unlikely, just a little end thought :)

TLDR: For the first half, I just explained Minas Strengths and weaknesses as well as her Special moves. The second half is me talking about how her quirk would work if it was based on some form of evolution.

Bnha rant #10

Its time for my favorite saga! The quirk analysis saga (which I will definitely be revisiting again after I've cleared all the rants I've already written)!

I wanna start the saga off with my base theory for everything. By that I mean, this is an entire different thing from canon and is where I think quirks come from. However, in future quirk analysis's I will include one that is based on canon and one that is based on my own theory. Now onto the theory :)

I believe that quirks are advanced form of evolution. My reasoning for this is that a lot of the people of the my hero world have quirks that can be explained by evolution (ex. Mina, Momo, Bakugou, etc.). I’ll get into explanation about a lot of this evolution when it comes to specific people.

You'll see this theory used a lot when it comes to my analysis of Mina and Momos' quirks especially. But, to backtrack on what I said, I think quirks are based on evolution. Every quirk has some way to be explained via science and evolution. Looking at Mina and Momos' quirks are actually where I got this theory from! It's kina hard to explain by itself but I can tell you Minas analysis is next and so you'll see this used more there (^^)

TLDR: I think quirks are based on evolution and have evidence to base this off of that you'll see in future rants.

Aight quick question:

What happens if Aizawa erases Mr Compress’ quirk and he has things stored in his marbles? Do they just un-marble?

Hello Sero Fans!

I have news of which I have recently extrapolated as weird pseudo science.

Right most of you will be aware that you can make natural glues with animal produces, a protein called Collagen, primarily found in high quantities in mammals, it's found in.

The Skin

Bones

Tendons

Cartilage

Ligaments

Now Collagen is used to make Glues and Tapes, for tapes specifically as that is what we are interested in here is used specifically in Water Activated Tape, as it's noted that prolonged usage can Dehydrate him, lending credence to the idea that is tape is water activated. So it's likely that it's sweat activated from him, but it is possible that it can be set to activate when in contact with a damp or sweaty object, EG: Human, Bakugou.

Now because his body needs produce greater amounts of Collagen, that means he can also probably make everything it's contained in in a shorter timeframe, which makes sense.

This also means that he, and I'm saying this as a hypothetical, he has increased Regeneration, now I'm not talking anything like Wolverine levels, but rather he can heal faster from broken bones and pulled tendons, and possibly damaged skin, so it's possible he can heal off scraps and burns faster than the average, by MHA standards human.

So primarily his quick creates Tape, but what I'm calling a Mutation, because that term is used next to nowhere in MHA, is that this excess Collagen is used to strengthen his Tendons and Ligaments, hence his ability to swing from his elbows unfettered without majorly throwing out his shoulders, his Tendons are stronger.

In short, his quirk is simply produces shit tons of Collagen in much the same way that Bakugou produces shit tons of Nitro Glycerin.

In short Hanta Sero's Quirk has a pretty neat possible biological system inbuilt into his bone that not only makes him more durable, but makes him able to heal of damage faster, if only marginally.

How is this the best explanation I've seen of Hagakure's quirk, like genuinely.

And it's for a rewrite, like no that is just how I'm going want her quirk to work now, it makes so much sense.

Quirk Analysis #1

As promised, this post is for the quirk analysis of the following three students!

Kirishima Eijirou, Ashido Mina, Hagakure Tooru will be discussed in this post and in that order.

Kirishima Eijirou:

Fatty and oily foods make Eijirou's skin harder, and Izuku hypothesises that it's due to the carbon content. While carbon is often associated with gases or coal, it's in food too, with the content being higher in oily or fatty foods. Eijirou manipulates the carbon in his skin by rearranging the carbon molecules to make it denser, to the point that his mohs level of hardness is equivalent to corrundum (level 9, one level below diamond).

Because of this, eating food containing high levels of carbon makes it so that there's more carbon to push between his skin cells.

While ordinary humans cannot properly digest high levels of carbon, Eijirou's body is able to, not just handle it, but properly digest it. As such, he starts eating activated charcoal, (which is safe to eat in small dosages, though Eijirou can have more), which increases his time limit, and can help him harden his entire body for longer periods of time.

It's also theorised that his teeth are sharp so that he can bite into coal.

Ashido Mina:

The most obvious contender for what her acid is made of is stomach acid, however, if she transported her stomach acid to her skin, it would make her either incredibly ill or she wouldn't be able to digest things, as she subconciously produces acid.

As such, it's much more likely that she's using carbon dioxide. It's usually pointed out as a gas, but it can exist in a liquid form. Carbon dioxide naturally exists in all humans, though typically as a gas that our body filters out through breathing. Mina is absorbing carbon dioxide as opposed to breathing it out and changing it to a liquid form.

She can alter the pH levels, though it's naturally low, around pH level 3, which leads to accidentally dissolving her bed and floor and waking up in the flat/apartment below. Don't ask. She can make the pH levels go up to about 7, which is safe to drink, though it's not recommended, and this allows her to use her acid to slip around the ground.

While she could theoretically try breathing less to increase carbon dioxide intake, but that's very dangerous without proper training. Instead, she takes sodium bicarbonate or sodium citrate pills, which increase the level of carbon dioxide in the body.

Her appearance is not connected to her quirk.

Hagakure Tooru:

Now, if Tooru were truly invisible, she would not be able to see, as the way we see is by light hitting our retinas, which bounces the light to the photoreceptors behind them which send the electrical signal to our brains. If the light passes through you, the light can't hit the retinas, meaning that no information would be sent to your brain, leaving you blind.

As such, reflecting light also cannot be her quirk, as this would lead to the same results, and would make her continuously shine.

Her quirk is actually absorbing and manipulating radiation across her skin. She doesn't feel hot or cold, as seen by her steaming lunch and how she can run around naked without a single shiver, and this is due to manipulating the thermal energy, which is a form of radiation.

Light is also a form of radiation, which is why she can produce flashes from her skin.

This could also mean that she cannot become irradiated by things such as chemical energy, though it's far too dangerous to test out.

Additionally, because of this, it's possible that she can manipulated energy across things made of her DNA, which is proven true when she gets her costume and appear invisible after she wears it.

...

So that's Izuku's analysis of Eijirou, Mina, and Tooru's quirks!

I'm not a master of science, so if there's something that doesn't seem quite right, chalk it up to psuedo-science, please. I did not take A-Levels for science. My knowledge comes from my own research, mainly due to Momo's quirk.

Thanks for tuning in!
