In Hindsight I Think I Would Make Four’s Grandpa A Physical Therapist For Weapons Instead Of A Blacksmith.

in hindsight I think I would make Four’s grandpa a physical therapist for weapons instead of a blacksmith. Are there even blacksmiths in soul eater? 😭

I think him being a weapon specific physical therapist would be kind of a fun play on him being a blacksmith in other stuff, they both work with weapons, and it would make sense for him to be able to help out four

LU Soul Eater AU: Four

I must admit, Four has a really edgy 2014 lab AU that I spent too much time thinking about. I did have fun though so here’s his backstory and a trigger warning for unethical human experimentation. I don’t think it’s anything more graphic than what would be in Soul Eater.

A small disclaimer: I’m going mostly off of what I remember from the manga for any sense of canon, I haven’t had the privilege of playing the game yet. 😔

I think I mentioned before, but each of Four’s colors are a different type of knife. Together they’re able form the four sword.

Green is a machete. 

I decided on that for him because I think that machetes look really dangerous, showing up in a lot of horror media, and can cause a lot of harm, but that is not what they are meant for. Machetes are meant for clearing bush and foliage away to clear paths through forest or jungle. They can be used to obtain resources. A trailblazer or leader might use this knife. Green grew up with his father who was a captain in the royal guard. Green was being groomed as a weapon for the Princess Dot. Upon manifesting as a machete, a lot of people, especially Green’s own father, were disappointed and believed him to be a poor weapon for a princess looking crude and brutal. Together, Dot and Green proved the masses wrong, with them both proving themselves as leaders before fighters. 

Vio is a throwing knife. 

Vio is a child runaway. I can’t figure out what would be a good reason for him to run or what his family would be like, but I imagine he learned a dangerous secret. I also like to think that despite Vio being very smart, he can be unreasonable and is able to rationalize himself into making bad choices. He’s a throwing knife because it takes a lot of learning and skill to be able to wield a weapon such as that. It also takes something crazy to throw your weapon away from you and be able to rely on it to return. Vio can be recalled by his meister, but it has to be of his own accord. He can also control his flight to some degree. Up until the events I’ll describe in a minute, he had never been wielded before.

Blue is a trench knife.

In the background of the events during my story, there’s a war raging in the background that’s much more prevalent in Warrior’s story. This has caused a lot of children to be orphaned, Blue included. He grows up in a poorly funded orphanage and gets into a lot of fights growing up. I chose a trench knife for Blue because it is a very brutal weapon, something which I think he can be. It’s also a weapon that when you use, you know that you are aiming to really hurt your opponent and that you have to get really close to do so. There are also two main ways to use a trench knife, the blade, ofc, and the brass knuckles which I think kind of show how Blue thinks outside the box, especially in combat. It’s also a weapon that’s mean to be used when your back is against the wall.

Red is a Switchblade.

Red also grew up in an orphanage also due to the war. He and Blue grew up in the same place but weren’t close with each other. He definitely grew up more of a lover having a high level of empathy. Despite being picked on, maybe bullied a bit, Red is the type of person who never wants to hurt somebody else even in self defense. I chose the switchblade for Red because it kind of conceals its nature most of the time hiding in a sheath. A switchblade is a weapon that has to be used in close quarters, but unlike Blue’s trench knife, the opponent might not even recognize it as a weapon until it’s too late. Switchblades are spring loaded and fast, but by pressing a button, the user has a lot of choice before they use it. I think Red would be able to stop himself from being triggered in his weapon form if he tried hard enough.

All of the four were born in the same year, all being roughly the same age. (Yay this means I can choose their zodiacs!) When they were all 11, each of them were kidnapped in the same winter by a witch called Vaati. Vio was first, being a homeless child he was hungry enough to be lured in by the prospect of working for food and board. This later would be something he feels ashamed of thinking himself more clever than that. Next would be Red who thought he was helping an elderly woman carry her groceries home… into a dark alleyway. Blue would be next, probably just being classically kidnapped after he poked around somewhere shady. Green would be the last, going on a personal mission to investigate the rapid disappearance of kids from the city he lived in. 

Vaati is a witch who is trying to make weaker weapons stronger in order to arm the army of the ancient evil (ganon) that he and many other witches are trying to revive.  For his first experiment, he wants to fuse several small/young weapons into one big stronger one. He chose the four because they’re young enough to be malleable but old enough to actually be able to turn into their weapons. They also conveniently have a lot in common, age, gender, and weapon type which Vaati thinks will make it easier to fuse them.

Vaati begins a series of experiments that don’t really seem to make sense to the four. He’ll force them all to work together to complete puzzles only to rip them apart for the next few. Vio, who’s been there the longest, plays along well knowing what to expect. Green, who’s been training already for a long time, doesn't struggle too much with physical or mental challenges. Red and Blue however struggle a lot causing Vaati to use crueler and crueler experiments to get them to obey.

Vaati’s struggle with Red and Blue resides in that Blue fights back the most and is actually quite brawny for a tween and Red won’t fight at all refusing to take his weapon form and even if he does, he won’t unsheath. Blue is something Vaati must subdue and break in. Red is something to trigger. He routinely exposes them to extreme temperatures, Blue the cold and Red the heat, and subjects them to frightening simulations. (I’m basing this off the manga with blue being frozen, red in the burning village, the giant poe)

Most confusingly, he makes the four wield each other which is not natural/impossible for weapons to do. Vaati achieves this with the help of magic.

Vaati works using his own son Shadow as an assistant. Shadow is a similar age as the boys and enjoys the power he gets to lord over them. Secretly, he’s really happy to have so many other kids around. That being said. He hasn’t been properly socialized so his idea of trying to play with them is just by mildly tormenting them. 

Vio is the first to start befriending Shadow. Like in the manga, he does this with the intention of later betraying him, planning on using him as means to escape. He unexpectedly begins to genuinely like Shadow and starts to experience extreme guilt in thinking about what he’s going to do. Nevertheless, Vio begins to start faking Stockholm syndrome. This is really confusing for the rest of the boys. Blue thinks that Vio is bad person and is actually siding with Vaati. This leads to a fight between them that results in Vio being separated from the rest of the boys. (I didn’t mention it but they’re usually locked in the same room between experiments.) Red believes that Vio actually has Stockholm syndrome and feels really bad for him. Green can see through Vios' plan but just thinks that it’s a really bad idea. He doesn’t say anything though because he doesn’t want to ruin it for him just in case it does work. 

Red is the next to befriend Shadow, though it’s unintentional. Despite everything, Red does his best to remain kind, maybe not so much to Vaati, but to Shadow, sure. Red thinks that Shadow is just a brainwashed kid, which he’s kind of right about. Shadow starts to like Red because he’ll go along with any game he wants to play. 

Green falls after Red gets more chill with Shadow. The games they play look fun and Green really didn’t have a lot of chances to play growing up. He starts to take a page from Vio’s book, trying to pry information where he can from Shadow. Somehow he feels less bad about this than Vio does. 

Blue thinks everyone is going crazy in here so he takes to verbally bullying Shadow whenever he swings by. Shadow, being a weirdo, thinks that it’s a form of banter so he just bullies Blue back. Unexpectedly, and to his own horror, Blue finds it really fun to be able to have a witty back and forth with somebody who can match his level.

Shadow for the first month or two is really his dad kidnapped people his age. It’s so FUN having people to play with! He even has a best friend now in Vio. He doesn’t really think about the implications of his dad hurting his new friends, and his role in that, until they start acting different. 

Vio starts having panic attacks (out of nowhere!/s) and can take hours or even days to calm down rendering him unable to even speak. This is the first thing that rattles Shadow. It’s the first time he felt hurt seeing somebody else hurt. His attempts to calm Vio down begin selfishly, wanting him to stop acting weird and to start acting like his best friend again. Eventually it turns into genuine and raw concern. Shadow, for the first time, feels bad because somebody else does. He starts just really wanting Vio to be okay. 

His other playmates start breaking down too. Red is too exhausted now to play. He sleeps most of the day away and when he’s awake he’s too shaky and weak to do anything. Blue becomes dissonant, stuck staring at walls. He won’t respond to even the strongest of Shadow’s remarks. Green is caught between caring for the other two. He becomes too busy to try and pry information out of Shadow.

Then a day comes where Vaati gathers each boy and throws them into the middle of a collection of runes drawn on the ground with a combination of their blood. A flash and they’re all rendered into their weapon states, unwillingly. After a few moments there’s another flash and only a single weapon remains. The Four Sword. When the weapon takes its human form back, only one terrified boy stands sharing features of the four that formed it. 

Despite Vaati’s satisfaction, Shadow feels that something REALLY wrong just happened, and it did. He later visits “Four. Four is shell shocked, barely able to walk, confused, and really, REALLY scared. He looks at Shadow and begs him to let him out. Shadow obliges.

Picking up the newly formed Four sword, Shadow vanquishes his own father and runs with his new friend Four. Shadow was greatly wounded in the fight, his father cursing him to never stand in sunlight. Four is traumatized and so confused. He decides to go to Green’s father, now technically Four’s father, unsure of where else to go. 

The two boys tell the story to Four’s dad and a proper raid is unleashed on Vaati’s lab, leaving out the parts where Shadow was Vaati’s accomplice for most of the time. No body is found. Four’s father tries to defuse him, which just terrifies him. Shadow gets some medical treatment but most people don’t want to treat him, as he was Vaati’s son. 

Four’s father, unsure what to do with two traumatized children, dumps them on his father, Four’s grandfather who lives out of town as a blacksmith. There they all heal and after a few years learn to defuse. They’ve all spent so much time together though that they can’t bare to part. They are literally part of each other now. Green’s father decides to give them all knight training and Shadow learns how to wield each of them and Four properly. They all know how to wield each other too but this is uncanny for a lot of people. Weapons wielding weapons… 

Shadow goes missing at the end of a dangerous mission. All too soon, Four is called to accompany 8 others on a holy quest. He sets out determined to save the world and his best friend. 

And that’s Four 😭 goodness that ended up a lot longer than I expected. 

Please, and I’m begging 🙏🙏🙏, let me know what you think, your own headcanons, critiques, questions, ANYTHING. And who you’d like to see next! 

Thank you 💕
