## **Backstory**

Art by Kiezi UTa

The 4th Omni is the fourth of the five brothers created by the self-worship of the followers of their religion. Since they were created as physical bodies, perhaps for a long time they lived and worked, helping the ancient monsters. But one of their brothers feels that the monsters are just trash, born arrogant, he refuses to help monsters and is the one who often spreads disease, famine, war... The followers gradually hated him and removed his name from the almighty gods, and erased his information to prevent posterity from knowing. The other brothers stopped and destroyed him, but before he died, he prophesied that he would endure as long as pride, famine, war, disease... persisted. Although the records of the 5th god have been destroyed, it does not mean that completely, just through small stories like to scare children, gradually there are extreme religions worshiping him. The year 2090 is also the time to hide his return and once again spread disaster.

After the first war, the remaining 4 gods left the earth and lived in their own dimensions behind reality. When the 5th god returned, the 4th Omni and his brothers tried to stop him again but failed, 3 of the 4 were killed and only the 4th Omni remained. But at the moment of being killed, Osirus saved him with the excuse that "he wants to be responsible for his product", and then the Zero!Tale universe was wiped out by the number 5 god, he I've been lurking across the multiverse and the 4th Omni has been tasked with finding him. While searching for the 5th god, he found the book Nobody.

Later, the 4th Omni also had to participate in the 2nd War of the Gods, so temporarily put aside the search for the other 5th god, but he never stopped.

## **Appearance**

4th Omni wears a white hoodie, white tracksuit with a red x in the center of the chest. Sometimes the sleeves will be lined with a red circle. The cap is white with a red circle on the top, and the fluff is light yellow. Black sweatpants and white shoes. The cuffs on the sides are yellow and purple. His hands are the same color as his yellow and purple collar, purple and red eyes.

## **Personality**

4th Omni doesn't show much emotion but he really likes to joke when he's comfortable. However, he tends to hate children or young teenagers because he considers them noisy, impulsive and harmful. 4th Omni is a good teacher with many years of experience, he loves his students very much even though it contrasts with his thoughts of hating teenagers even though his students are all teenagers. He is still constantly searching for his 5th brother and constantly looking for ways to revive his universe. He is smart, calm and loves to fight.

## **Abilities/Magics**

The 4th Omni's Magic is very powerful, however it has been greatly weakened as the followers are gone and he has lost his source of power from them. However, with his own efforts, the help of Osirus and many people, and learning from the book Nobody for a long time, the 4th Omni became strong with new powers.

* Basic Magic
* Enhanced Magic

**Idolatry**

Created by believers and the 4th Omni as well as many other brothers, he received enormous power from his worshipers, however it waned as the followers gradually decreased as life has become more modern, until finally when the universe was wiped out, he lost this source of power.

### **Light Beam**

4th Omni shoots out a white beam with a yellow aura, possessing an absolute heat of 1,417,000,000,000,000,000,000,000,000,000,000 °C, he can also raise the temperature above the absolute maximum, infinitely or more. This skill can still be used later.

### **Shadow Beam**

Shoots out a black beam, surrounded by a purple aura. The opposite of Light Beam is absolute heat. Shadow Beam is Absolute Zero with a temperature of -273.15°C. The 4th Omni uses it to prevent regeneration and regeneration at the quantum, atomic, molecular, etc. Levels, causing particles to stop moving and bonding. Shadow Beam also sucks and crushes everything it touches. This skill can still be used later.

### **Reality Black Hole**

The 4th Omni can create a black hole of any size at will, it will suck and crush everything in the space where it appears, bend, distort and gradually erase reality and everything in it. It can even entail destruction with all the branched timelines of the universe it destroys. This skill can still be used later.

**Elemental Manipulation**

He is the god of the element, so he can manipulate the element that exists in the universe. This ability was later lost.

### **Infinite Energy**

4th Omni has an unlimited amount of energy in his body due to his partial connection with Layer 3 ( Megaverse ). This allows him to fight continuously without feeling tired or weak as long as he remains affiliated with that Layer 3. He can use this energy to create spheres, beams...

### **Immortal**

He is closely linked to the aura in front of his chest, it cannot take damage. This red aura is again closely linked to a gem in Layer 4. As long as that stone exists, he will remain. However, this stone exists in infinitely different timelines because a stone itself is a Megaverse. Originally, the 4th Omni only had abilities like regeneration, regeneration, and infinite lifespan.

### **Horizon Blaster**

Like a normal Blaster but its destructive power is extremely high. It can completely obliterate anything between and below Mega Horizon. This destructive weapon draws its power directly from the infinite Megaverse.

### **Copy**

He can copy anything from his enemies as long as they are a code creature.

### **Hell Dimension**

4th Omni creates a dimension larger than Mega Horizon. Suppress and erase all basic concepts, logic, definitions, causality.... Make him invincible in his dimension.

**Zeta Zero**

A powerful technique. The 4th Omni brings Z0 into existence, which is said to be the collection of any infinite set of cardinals. This makes it possible for the 4th Omni to overcome the infinite because according to him, the infinite is just Omega and he imposes this law on the world by The Truth. This is beneficial as his attacks enhanced by Zeta Zero will be nearly invincible.

### **Shizenku**

One of the most powerful of the 12 ancient celestial weapons. Shizenku is a long sword, many say it predates space and time. It is so heavy that even the concept of infinity cannot be compared with it, and only those chosen by the sword itself can wield it. Shizenku deals an inexplicably large amount of damage despite the fact that its power characteristics depend on the owner (how strong the owner is, the stronger the shizenku is) but maybe that's wrong. it can slash anything as easily as cutting butter and is not bound by concept. It was a real living being, not a mere weapon.
## **Transformations**

* I.N.T.E.L.L.I.G.E.N.T
* Change The World

This transformed form will send you into infinite layers of hell dimension, where you will encounter him in his strongest form. It's **I.N.T.E.L.L.I.G.E.N.T**

In this state, it will magnify all of the 4th Omni's skills and powers to absurd levels, surpassing the limits of the form itself repeatedly every millisecond.Everything is nothing now because you will not be able to protest in his dimension.

However, in this form is when the 4th Omni uses the bracelet on his chest, using infinite stones, which bind his life to him. This form pressure will destroy each stone in an alarmingly fast time. If used for too long, this stone will disappear from absolute existence, killing him instantly, forever unable to regenerate or return.

This is the form when the 4th Omni allows the evil, dark side of itself to control the body, it will create a fire demon, saying that it has the ability to change the world, which is also the name of this form "Change The World" or "4th Omni: Change The World". This form must be ensured by the 4th Omni to ensure the safety of its allies by making a contract with its "dark side", because it is a crazy beast but still has a clear sense of what it is doing, so so in order to avoid causing harm to themselves and others, 4th Omni must. The evil personality of the 4th Omni is called Griffon himself.
