The Epic of Leviathan

I wanted to write this up for quite some time but it only became possible today. I wanted to explain about the Omniverse in which the story is taking place.

First of all, let me explain what is Omniverse:-

Omniverse is a verse, which contains everything that exists, besides other things that go outside of normal existence., including nonexistence. It just contains all the verse that contains all existence and all the verses that contain existence. That's it, existence and nothing but existence. The Omniverse is the largest official verse.

Within the Omniverse, everything exists, like the MHA World or simply the MHA Multiverse, Harry Potter World, and the Harry Potter Multiverse. It's the same thing with the current world in which the MC is residing in. In the future, even the Bleach Multiverse and the Highschool DXD Multiverse will be a part of this Omniverse.

So, in simple words, my whole story is taking place within the Omniverse. Even though MC and the girls are traveling to other worlds they are still residing with the Omniverse. Only because of this reason MC can travel back to any world he had been to.

Now, God who gave Reo all the power and killed the previous God of Destruction is the Supreme Ruler of this Omniverse but he can't interact directly with any mortal beings or interfere with any Mortal Worlds. That is the reason God still has to show himself the MC and the girls. This is also the reason God is asking for MC's help to complete the given missions.

Now, God can only interact with Cosmic Beings… beings like Cosmic Entities, like the Leviathan of Destruction or the Phoenix Force. I will continue explaining this later.

Now, some you might ask me then what about One Above All??

One Above All is still a Godly ruler, Supreme Being… whatever you want to call him. But he is the Supreme Being of Marvel Multiverse, not the Omniverse. There is a known or unknown Supreme being residing within every known and unknown Multiverse. This is the same for all the Multiverses residing within the Omniverse.

There are some other Gods too but they are not part of any Multiverses. These Gods are called Outer Gods, they are known by other names too but they are commonly referred to as Outer Gods. They generally lurk around the darker parts of the Omniverse and attack some Multiverses from time to time.

These Outer Gods are very strong entities… but they are no match for the God ruling the Omniverse. Now, some of my readers can already guess where I am going on with this. After all, a DXD is a famous series, I won't say anything more, for now, not wanting to ruin your fun.

Now, let's talk about the Cosmic Entities. There are several Cosmic Entities within the Omniverse but only a few of them can stand out. Like Rebirth (Phoenix Force), Destruction (Leviathan of Destruction), Galactus, Aegis (Lady of Sorrows), Atum (Demogorge), The Living Tribunal, or The One Above All.

Now, let me make it clear, I know that the Concepts like Eternity, Infinity, or Death are also Cosmic Entities but I didn't include them in the previous list because they are also concepts not exactly beings like the ones I mentioned before. In Marvel Multiverse, Death is represented by Lady Death but in Bleach Multiverse, it is represented by the Shinigamis.

Within the Omniverse there could be only one Cosmic Entity of one type, like other than MC there can be no other Cosmic Entity who could become the Leviathan of Destruction. Yes, there could be another Cosmic Entity within the Omniverse that can use the Power of Destruction like the Gods of Destruction from the Dragon Ball Multiverse, but they can never leave the Multiverse because their power is connected with their Multiverse and there cannot be another Leviathan of DEstruction except MC.

Similarly, within the Omniverse there can be only one Phoenix Force which is inside Jean, there could be no other Phoenix Force within the Omniverse. So, Fleur will never become a Cosmic Entity as long as Phonix Force exists within the Omniverse.

Now, let's discuss the relationship between Jean and the Phoenix Force. Consider that Jean owns a scared gear but this isn't made by the God of the Bible, this is made by the Omni-God. Their relation is similar to what Vali and Albion have… (I would rather die than compare Issei with anything).

So, when Jean leaves the Marvel Multiverse along with the MC, it won't cause any problem because she will still be present within the Omniverse, like I said the Cosmic Entities are not only part of the Marvel Multiverse, but they are also a part of the whole Omniverse. So, as long as they exist within the Omniverse it won't cause any problem.

I hope that with this a lot of your doubts regarding the Multiverses would be gone…
