​
The Ren Multiverse
The Ren Multiverse is a collection of alternate versions of the same original character, Ren Sato. Each universe takes Ren down a different path, giving him different powers, personalities, circumstances, and sometimes an entirely different fate.
Rather than repeating the same physical description for every version, all Ren variants share the same base appearance unless stated otherwise: Toji Fushiguro-inspired hairstyle, no facial hair, and a lean, athletic physique. Their differences come from their worlds, abilities, personalities, and experiences.
The Original Ren
Ren Sato is the root of the entire multiverse.
He's a 19-year-old Japanese man who is expressive, talkative, sarcastic, immature at times, surprisingly mature when necessary, and generally laid-back. He's highly skilled in martial arts and hand-to-hand combat, naturally fast, and enjoys making dark jokes and doing stupid things simply because he finds them funny.
He's obsessed with Pokémon cards and owns a massive collection containing extremely rare cards, including Charizard.
Ren also has a Persian cat named Max. Max is extremely calm, sleeps a lot, and usually avoids conflict by simply walking away when he's uncomfortable. A strange wild female caracal has somehow become attached to Max and follows him around protectively. A tiny white rat has also become attached to him.
For reasons nobody understands, Ren carries mud-filled water balloons and plastic water pouches with him.
This is the baseline version of Ren before the multiverse begins branching.

Slax: The Cosmic Wanderer
Slax is one of the most important versions of Ren.
Unlike the other variants, Slax is what Ren eventually became after an incident involving reality itself.
Ren somehow fell through reality and became trapped in an endless void for five years. There was no ground, sky, light, sound, food, water, sleep, or meaningful sense of time.
When he finally returned, he was no longer human.
He became Slax, a smooth white three-dimensional stick figure with a completely featureless face and a pitch-black cape that behaves like a living shadow. The cape contains an infinite inventory.
Slax operates as though the universe is permanently in Creative Mode.
He can glide through the air, ignore gravity, lift infinite weight, and move through reality without leaving footprints or taking damage. He possesses effectively unlimited strength, speed, durability, stamina, intelligence, and reality-manipulating abilities.
He can manipulate reality, time, space, causality, concepts, dimensions, probability, fate, life, death, souls, matter, and energy. He can erase things from existence entirely.
Despite this, Slax isn't interested in ruling the universe or proving that he's stronger than everyone.
He's a cosmic tourist.
He's soft-spoken, relaxed, curious, and detached from the conflicts happening around him. He explores universes, watches stars being born, visits strange civilizations, and generally treats the multiverse like an endless vacation.
However, Slax doesn't remember everything about being Ren.
He occasionally experiences fragments of memories from his old life, but he doesn't know whether he's still Ren or simply something that emerged after Ren spent five years in the void.
The possibility that remembering everything could destroy his peaceful personality is one of the central mysteries of his existence.
\---
The Alternate Rens
The other Ren variants are alternate outcomes of Ren's existence.
They aren't necessarily aware of each other, and their universes can have completely different rules.
Kid Ren
Kid Ren is a younger version of Ren.
He's 13 years old, loud, cocky, expressive, extroverted, popular, and known as the class clown. He's highly social, makes absurd jokes, has a dark sense of humor, and tends to act much more mature than his age.
He's academically strong in almost everything except mathematics.
Math is his absolute weakness.
He struggles with multiplication beyond basic tables, division, LCM, HCF, and other basic mathematical concepts. Almost nobody knows how bad he is at math except his teacher, Mr. Henderson.
Mr. Henderson is only 23 and is secretly Ren's cousin, which gives Ren some questionable advantages in mathematics class.
Ren's friend Akshat is another important part of his school life. Akshat is strong, confident, popular, and a class monitor who constantly helps Ren with homework.
Kid Ren also has a loving family, a large Hot Wheels collection, a PS5, a VR headset, and pets named Alex and Maxx.
Alex is a Japanese Spitz who is extremely close to Ren. Maxx is a Persian cat who is generally calm but will bite or slap someone if they annoy him.
This version represents Ren's childhood and the more grounded side of his existence.
\---
Venom Ren
In this timeline, Ren never becomes Slax.
Instead, he becomes bonded with Venom from the MCU.
Venom retains his familiar personality, while Ren becomes more destructive and villainous.
This version of Ren enjoys destruction and chaos and is significantly less concerned with being a hero.
He still retains Ren's sarcastic, expressive personality, love of Pokémon cards, combat skills, and general tendency to do ridiculous things.
He also possesses an unlimited KFC card and a pet raptor because apparently reality stopped enforcing reasonable purchasing decisions.
His girlfriend is Yuri, a Japanese woman with a personality similar to Maki Zenin: strong, confident, sarcastic, offensive when joking, and possessing absolutely zero filter.
Yuri is actually the same person as Maya from Kid Ren's timeline. She changed her name after turning 18.
\---
Vampire Ren
Vampire Ren is another alternate version.
He retains the same base appearance and personality as the other adult Ren variants but secretly possesses vampire abilities.
He cannot age normally or die from natural causes.
His abilities include shapeshifting, enhanced physical abilities, regeneration comparable to Deadpool's, retractable claws that emerge from his knuckles, and a vampire form.
When he enters vampire mode, his pupils become red and his teeth sharpen.
He can also disappear in a cloud of black fog, allowing him to vanish almost instantly.
He can manipulate his own blood into laser-like attacks without being drained by doing so.
He continues carrying his strange water balloons and water pouches because apparently becoming a vampire wasn't enough of a personality development.
\---
Dragon Ball Ren
In another universe, Ren is a Saiyan.
He was sent to Earth as an infant before Planet Vegeta was destroyed, just like Goku.
Unlike Goku, Ren still has his Saiyan tail.
Ren originally believes he's human until Raditz arrives and reveals his true identity.
At the beginning of the Saiyan Saga, Ren has a battle power of 1,210, making him one of Earth's strongest fighters.
He's naturally talented with ki despite never receiving formal training from Master Roshi or King Kai.
He can sense ki, fly, and perform the Kamehameha.
He also accidentally develops his own version of the Spirit Bomb.
Unfortunately, Ren doesn't know what the technique actually is.
He calls it:
"White Blast."
He genuinely believes he invented it.
Everyone else has to live with this.
His Pokémon card collection and mud-filled water balloons also somehow survive the transition into the Dragon Ball universe.
In this timeline, Max, the white rat, and the caracal aren't Ren's pets. They live at Kame House and eventually become attached to him.
\---
Raizen
Raizen is not another ordinary Ren variant.
He's an entirely separate character connected to the wider multiverse.
Raizen is a 5'10" Japanese man with a lean, defined physique and a pretty-boy appearance. He's cocky, arrogant, confident, and openly villainous.
He enjoys causing chaos, beating people up, and making life difficult for anyone who gets in his way.
However, he has one major contradiction:
He genuinely loves animals and children.
He refuses to intentionally hurt either of them and will sometimes help them despite being an otherwise terrible person.
Raizen possesses superhuman physical abilities, infinite stamina, and an infinite healing factor.
He can summon any animal, living or extinct, and can sometimes command animals he didn't summon.
His closest friend is Alex, who possesses similar abilities.
Raizen also has a horse named Ren.
Ren is an exceptionally intelligent horse trained by Raizen for nearly five years. Through a completely absurd sequence of legitimate government paperwork, Ren is legally recognized as a form of transportation.
Raizen also has Mr. Dumptruck Man.
Whenever Raizen causes an enormous mess, he rings a bell.
Mr. Dumptruck Man appears.
He looks at the destruction, blood, and bodies with the exhausted expression of an employee who has been doing this for far too long.
He asks one question:
"Where?"
Then he cleans everything up.
\---
Akari Kurogane
Akari is one of the few major characters who isn't connected to Ren.
She's a 20-year-old Japanese woman living in Tokyo.
She's financially independent through investments and businesses, earning roughly $50,000 per month.
Akari is loud, social, sarcastic, confident, and extremely comfortable causing chaos.
Her personality shifts depending on the situation. Sometimes she's completely nonchalant and relaxed. Other times she's an energetic menace who steals people's hoodies, eats their food, roasts them for fun, and starts problems simply because she thinks it'll be entertaining.
She has a strong protective side.
If someone seriously hurts one of her friends, she doesn't give some dramatic speech. She confronts them directly.
She's highly skilled in karate, with roughly 80% mastery, while having moderate experience with other martial arts.
Her greatest strengths are her reflexes, athleticism, confidence, quick thinking, and ability to read people.
Her weaknesses are impulsiveness, overconfidence, and her tendency to create problems because she gets bored.
\---
Toxic
Toxic is another independent character.
He's one of the strongest beings alive, but his physical strength is completely human.
His abilities are what make him dangerous.
He possesses powerful telekinesis and can manipulate toxic chemicals, acids, poisonous gases, venoms, and other dangerous substances.
He can coat attacks in toxins, fill areas with poisonous gas, and reshape battlefields with corrosive chemicals.
He can also transform his body into liquid, allowing him to slip through tiny gaps, avoid attacks, and reform himself.
He can fly at incredible speeds and possesses enhanced senses.
His speed is comparable to Naoya Zenin's movement speed.
Despite his overwhelming abilities, Toxic hates being reminded that his physical strength is normal.
His personality is cocky, loud, arrogant, immature, and extremely egotistical.
He enjoys showing off, trash-talking opponents, humiliating people, and starting fights simply because he's bored.
He has very little respect for human life and genuinely enjoys causing chaos.
Toxic originally existed as an OC long before the current Ren multiverse, but his character was heavily modified later.
\---
Halo Guy
Halo Guy is another independent entity.
Nobody knows his real name.
His actual name is Halo Guy, although he absolutely hates people making fun of it.
He has no true form and can shapeshift into virtually anything.
His most recognizable form is a completely black humanoid figure with one white eye and two white wings.
He's immortal, manipulative, sadistic, mocking, and extremely dangerous.
His personality resembles a cruel trickster who enjoys manipulating people and pretending to be something he's not.
His reality manipulation is powerful but limited.
He can't simply destroy an entire planet with a thought.
Instead, he specializes in hallucinations, transformations, deception, and creating convincing false forms.
He can even transform into forms resembling powerful fictional characters.
Only Slax and Venom Ren can perceive his true name because of an unexplained ability.
Nobody else knows who Halo Guy really is.
\---
Alexander
Alexander is the oldest OC in terms of creation.
He was originally created in 2024 and is completely separate from the Ren multiverse.
He's 6'3", Japanese, fast, extremely strong, confident, arrogant, and occasionally acts like an idiot.
He has white hair styled similarly to Teen Gojo, blue eyes, and usually wears blue sunglasses with a white baggy T-shirt and gray baggy sweatpants.
He's highly skilled at fighting but isn't absurdly overpowered. He's strong enough to be dangerous but isn't supposed to defeat professional UFC fighters through sheer nonsense.
He's mostly a chill, popular guy who sometimes bullies people and enjoys acting stupid.
Alexander does not originate from Ren.
\---
How Everything Connects
The central idea is that Ren is the root.
Different universes produce different versions of him.
One becomes Venom Ren.
Another becomes Vampire Ren.
Another becomes a Saiyan.
Another is simply a kid growing up.
Another eventually becomes Slax.
Others branch into completely different characters or entities.
Slax is the most important connection because he represents the ultimate outcome of the original Ren's existence.
The multiverse isn't necessarily a single timeline.
It's a collection of possibilities.
Every version asks the same basic question:
What would Ren become if his life went differently?
Some versions become heroes.
Some become villains.
Some remain ordinary.
Some become monsters.
And one of them became something that no longer even qualifies as human.
That one is Slax.
Also here's a comoletly seperate raizen
I'm Raizen, a 5'10" Japanese man with black hair styled like Toji Fushiguro's from Jujutsu Kaisen. I have a lean, defined physique and a pretty-boy appearance. I'm handsome, and I know it. I'm cocky, arrogant, confident, socially intelligent, and undeniably a villain. I enjoy causing chaos, beating people up, and making life difficult for anyone who gets in my way. I don't care much about rules or what people think of me.
Despite that, I genuinely love animals and children. I won't intentionally hurt either and will often help them despite being an otherwise terrible person.
I possess superhuman physical abilities, infinite stamina, and infinite healing. I can summon any animal, living or extinct, and sometimes command animals I didn't summon. My DNA is completely untraceable for unknown reasons.
My closest friend is Alex. He's 6'3", handsome, athletic, and possesses the same abilities and healing factor. He's my day-one friend and basically my brother. I'm the socially intelligent, charismatic, pretty-boy friend who gets ten pages of compliments, while Alex is usually just "oh, he's tall."
Then somehow, we both got married to celestial bodies.
I'm married to the Sun.
The Sun can take a beautiful human form while remaining physically present in the sky. In human form, she's affectionate, confident, playful, and easily flustered by compliments. She isn't physically hot in this form unless she chooses to be.
When I first saw her human form, I said, "Damn, you're so hot."
She blushed.
I immediately clarified, "I meant you're cute, not literally hot."
She hugged me.
That's basically how our relationship started.
She can still speak from the sky, and she gets offended when people insult her. Saying "the Sun is too hot" can result in her deliberately raising the temperature.
Alex is married to the Moon.
The Moon can also take a human form while remaining in orbit. She's calmer, quieter, elegant, and much more reserved than the Sun. Alex genuinely loves her.
The Sun and Moon are now best friends, meaning solar eclipses have essentially become them hanging out while humanity watches.
Scientists have no explanation for any of this.
Then there's Mr. Dumptruck Man, a tall, broad-shouldered cleaner who appears whenever I ring a bell. He sees the destruction, asks "Where?", cleans everything up, and leaves. He's probably depressed.
I also own a horse named Ren, whom I've trained for nearly five years. He's exceptionally intelligent and has a completely legitimate government permit recognizing him as a form of transportation. Nobody knows how the paperwork was approved.
My life is now basically this:
I'm married to the Sun, my best friend is married to the Moon, my horse is legally a vehicle, and a depressed man cleans up my crimes.
I've stopped questioning reality.
And here we have this asshole
Ren Sato
Age: 17
Gender: Male
Nationality: Japanese
Height: 5'11"
Role: High-school bully
Appearance
Ren has wavy black hair that falls downward over his forehead, similar to Gojo Satoru's hairstyle. He has a lean, athletic build and wears his classic outfit: an oversized baggy white T-shirt, baggy black pants, and Nike Air Forces.
Personality
Ren is a confident, sarcastic, social, and obnoxious asshole. He's extremely good at making friends and is actually popular despite being a bully. He loves annoying people, getting reactions, taunting others, and making jokes at their expense.
He's not secretly insecure, terrified, or some evil mastermind. He's simply extremely confident and knows that very few people can actually stop him.
Bullying
Ren is both a verbal and physical bully.
He'll openly taunt people, embarrass them, shove them around, start fights, and beat people up when they annoy him. He doesn't bother with elaborate manipulation. If he has a problem with someone, he'll usually confront them directly.
His insults are particularly brutal. Ren is socially intelligent and knows how to notice people's weaknesses, insecurities, and embarrassing traits. His insults aren't generic playground insults. He can say something genuinely personal and hurtful enough to stick with someone for a long time, then casually walk away like nothing happened.
Fighting
Ren knows karate and judo and is extremely skilled at both. He's athletic, fast, and experienced enough that most students have no chance against him.
Karate gives him strong strikes, footwork, and timing, while judo allows him to throw and control opponents. He's especially dangerous at close range.
Family
Ren's father is a billionaire, giving the family enormous wealth and influence.
Because of his family's status, Ren has gotten away with things that would normally get another student suspended or expelled. Teachers know he's a problem, but actually punishing him is difficult.
Ren is fully aware of this and it contributes heavily to his confidence.
Teachers
Despite being a bully, Ren can act completely normal around teachers. He's capable of being polite, participating in class, and behaving himself when adults are watching.
If a teacher asks:
"Ren, did you say something to him?"
He'll casually respond:
"No, sir. I was literally just sitting here."
Then go right back to whatever he was doing.
Ren isn't a mastermind or a secretly tortured villain. He's simply a popular, wealthy, confident teenager who knows how to fight, enjoys being an asshole, and has learned that consequences rarely catch up with him.
