Different Verses: Leon is the guardian of the entire Omniverse and Background, but cannot create or destroy universes. The Omniverse is a vast space that contains multiverses that contain singular universes. A universe is a possibility for a unique timeline or series of events. A multiverse is a space that includes universes that have many of the same characteristics and common events. If two universes had Leon's brother Callith in both, then they could be in the same multiverse. If they do have the same shared number of the same events, then they are related or can be seen as a remix. The Omniverse contains multiverses that don't have enough in common to be in the same space. For example, most of the multiverses share the commonality of having gods or powerful beings, or humans inside. Entities can't cross universes without special powers like Leon's dimensional cutting ability to travel across universes. The reason why the Omnivurse is as far out as it gets is because it wouldn't make much sense for anything else to be a reason why an even bigger verse contains Omnivurses. It would be like trying to add one to infinity. The Background is the space between and around the Omnivurse, like an infinite soup of multivurses.
The Background is very dangerous for any type of mortal to be in. The temperature of the Background consists of 1 degree Kelvin and has an infinite flat, dark, and glassy plane, sort of like obsidian. In the Background is the altar where Leon rests when he gets his fill back up on energy after one week to 7 months of rest. Leon is kept down by multiple chains to discourage him from disrupting his rest. While Leon is asleep, the guardians under the floor around him will make sure nothing tries to mess with Leon during this stage and will be cast back to their universe with no memories of how they died or of the Background. Leon takes in energy from the darkness in the place as a food source. Leon gains intel as he rests, which slows down the growth of his IQ, leaving him at an IQ of 777.
Leon wears armor and carries weapons made from a super-strong, dark material. This material is incredibly tough. It cannot be broken or destroyed, no matter what hits it. It is also very heavy. Each square inch of it weighs about one pound. That might sound impossible to wear, but Leon is strong enough to move around like it is nothing. Most people would be crushed under the weight, but not him. His armor protects him from powerful attacks and makes him look like a fearless warrior. When people see him coming, they know he is not someone to mess with. Leon does not just rely on his armor, though. He also carries four amazing weapons with him at all times. These weapons are not normal swords or axes. They are powerful and rare tools that were made for a warrior like Leon. They are called the Cosmic Axes, the Cosmic Razor, and the Back Machairi. Each one has its special abilities. These weapons are unlike anything found in any other world or galaxy. The most special weapon Leon owns is the Cosmic Razor. This is not just a weapon used for fighting. It has a special power that lets Leon travel across different dimensions. All Leon has to do is think clearly about where he wants to go, and the Cosmic Razor will take him there. It listens to his thoughts and opens a path to the place he wants to be. This lets him move between worlds and universes faster than anyone else. The Cosmic Razor might also have an even greater power. Some believe it can destroy something called a dimensional rift. A rift is like a rip or tear in the fabric of space. If it is not stopped, it can cause an entire universe to fall apart and die. But if Leon uses the Cosmic Razor on the rift, he may be able to close it for good. When that happens, the universe will not be destroyed. Instead, it will be recycled and brought back to life. A new version of the universe will be created from the pieces of the old one. This gives the universe a fresh start. Because of this, Leon is not just a warrior. He is a traveler, a protector, and maybe even a savior of worlds. His armor and weapons are more than tools. They are part of who he is. With the Cosmic Razor by his side, Leon has the power to change the fate of entire realities. He is a hero in a battle much bigger than anyone can truly understand.
Leon's body is very unique and built in a way that makes him almost impossible to kill. He is able to survive in the most dangerous places, even black holes. If Leon ever gets pulled into a black hole, he will not be crushed or destroyed like most things. Instead, he will be cast into a place called the Background, and he will come out of it completely unharmed. This shows how powerful and unbreakable he really is. His body can handle extreme situations that no one else could survive. Even though Leon is nearly invincible, he does have one weakness. His only true weakness is something called Ichor, also known as God's Blood. But regular Ichor is not enough to harm him. In order to actually break through his skin and hurt him, the Ichor has to be mixed with carbon and plasma. This special mixture creates a dangerous serum that burns through his body like acid. It is the only known thing that can kill him, and even then, it only works for a short time. If Leon is ever killed by this special form of Ichor, he will return in around 7 hours. He wakes up in the Background, fully healed and ready to fight again. Every time he comes back, his body gets stronger and more used to the Ichor. Eventually, the Ichor will stop working unless it is changed again and made even more powerful. This means that over time, Leon could become completely unstoppable, with no weaknesses left at all. His ability to survive, come back stronger, and adapt to even his one weakness makes him a true legend.
Leon stands at 7 feet 2 inches tall and weighs between 300 to 340 pounds. His size alone makes him look powerful. Leon's body is different from normal people. Leon's blood is black and can get extremely hot, reaching temperatures between 200 and 300 degrees Fahrenheit as it flows through his veins. This heat makes him even more dangerous during battle. Leon only has one working eye. The other eye is scarred over with the same dark, indestructible material that his armor and weapons are made of.
Leon also has the ability to transform into another form known as Back-Omen. When he morphs into this form, his body becomes even more powerful. He grows two huge sets of wings that spread out to give him a wingspan of 20 feet. Along with the wings, he grows three long tails, each one stretching out 42 feet. At the end of each tail is a blade, sharp enough to cut through metal. In Back-Omen form, Leon's height increases to 10.7 feet. On top of his head, he grows horns that are each 6.9 feet long. His face changes completely. He has no teeth and no eyes. Instead of seeing, he uses echolocation, like a bat. This allows him to see by hearing sound waves bounce off objects around him.
When Leon flaps his wings, he can fly at speeds so fast they reach Mach levels. This can break glass around him and even cause people's eardrums to burst if they are too close. His legs also change. They become digigrade, which means they bend like an animal's legs, helping them run faster. In this form, he can reach speeds up to 77 miles per hour while running. All of Leon's weapons also change when he becomes Back-Omen. They fuse together into one massive weapon called the Phantom Razor. This giant axe is heavy and powerful. It is said that it could split a tank in half with just one solid swing. The weapon glows with energy and is nearly impossible to stop once it starts moving. When Leon is finished with the Back-Omen form, he can turn back into his normal human form without any damage to himself. When this happens, the Phantom Razor splits apart and returns to being his four separate weapons again. He can change forms whenever he needs to, giving him the power to handle almost any battle or threat. Leon is more than just a warrior. He is a living weapon with strength, speed, and powers that few can match. Whether in his human form or his Back-Omen form, Leon is a force to be feared and respected.
Callith and Callith have many of the same abilities as his brother Leon, except the ability to come back after death or to transform into a monster. Their blood is also black and reaches the same temperatures as Leon's. Callith is very strong and intelligent, with an IQ of 256. Callum is Strong with an IQ of 169. Both brothers were completely ritualized, unlike Leon, making them both strong and giving them the motive to destroy mankind. If Callum hadn't died, he would have joined Leon and Callith's side without the struggle to be under Ryoth's strong influence. The only reason why Callith was able to turn on Ryoth was because of Leon's words to think about all of the good reasons why mankind isn't all that bad. Callum, on the other hand, was far more stubborn, making Leon's words seem useless to him. When to thime they fought, it gave out a lot of emotional connections between Leon and Callith. When Callum was devoured, it broke both of their hearts because they knew Callum was scared to turn on Ryoth's believing he would be punished. Before Callum died, Ryoth kept talking in his head to get him to stay with him to continue his plans, the escape the Background and into the world. When Callith and Leon figure out that the Ryoth may have just killed them as well when he got out, they warned Callum that he would just kill him too, making Callum even more paranoid to think that they were trying to get him killed. When the moment Ryoth came out of the portal, they all knew his plan, but stood strong to escape for Callum. He was in shock, keeping him in place with fear to evade getting consumed.
Ryoth was the god of eternal oblivion, also known as the Void between dimensions, but that wasn't entirely true. Though banished by God from his original otherworldly domain, Ryoth still ruled over eternal oblivion from a place called the Background, a kind of cosmic trash pit where he also created a being named Leon. In this universe, gods could exile others but also allow them to return. Eternal oblivion was a brutal afterlife reserved for souls who had fully embraced all seven deadly sins: envy, pride, gluttony, greed, lust, sloth, and vengeance. These souls were stripped of all senses and movement for 777 years before being given a chance at redemption through reincarnation.
Each person would be reborn into a harsh life centered around their most dominant sin those with envy were put into lives of constant dissatisfaction, while the proud faced humiliating experiences, the gluttonous were born into hunger, the greedy into lives of thankless labor, the lustful into lonely, painful existences, and the slothful often faced physical disabilities. If they changed for the better, they could finally go to Heaven; if not, the cycle would repeat endlessly. Unlike multiverses, afterlives like Heaven or Hell exist as attachments to a universe, not separate ones, and they continue even if the universe dies.
Eternal oblivion was protected by giant winged serpents who would devour any uninvited intruders, forcing them into reincarnation with no memory of their past. Ryoth's job was to oversee this process until he lost control, and Satan took over with Hell, which operated similarly, except people waited 100 years before being reincarnated and faced endless cycles of torment and rebirth until they became good enough for Heaven.
The Illegal prison where Leon, Callith, and Callith were taken to was run by Cameron Lammy, a guy who thought he decided who could and couldn't live. It was only a matter of time before Ryoth gave two of his sons the power to break free and slay people to set him free. In the process, this caused the death of Cameron's wife, which made him vengeful and bloodthirsty. Over the years, he worked with the government, with his crimes hidden. To build a plan to find and kill Leon and Callith, Cameron built up trust with Commander Saquin as an ally. Commander Saquin suddenly went missing after he killed Callith and Leon. Saquin planned to kill anyone who knew about his doing weather he dies in the process, so he killed them before Leon and Caillith at another time. Only Leonto returns after death.
