Chronicle X ending details
1) Due to the collapse of the Old Digital World caused by Ogudomon X, Omegamon X and Alphamon traveled to the Kernel, the Realm of God, where they used their own data to stabilize the ODW. Other Digimon remained in the fight against Ogudomon X
2) Ogudomon X is erasing most of the world data, there aren't any lights in the skies, only the darkness nothingness while the world is attacked by Diablomon X. In the end only Gankoomon X, Jesmon X and Dukemon X are still capable of fighting:
3) The Diablomon X created by Ogudomon X are normally weaker than average Ultimate Level Digimon, but the amount of them is too big, in fact Ogudomon X is able to infinitely create Diablomon X
4) Ogudomon X power is explained, by Dukemon X, to be "too close" to the System, God, Yggdrasil power. In fact Ogudomon and Yggdrasil are complete opposites, equally god. They can't defeat Ogudomon X because no one has enough power to defeat God (Yggdrasil). However, Gankoomon believes that's possible to defeat even God
5) Ogudomon X data is said to be similar to Yggdrasil data and the idea of Digimon being unable to harm these entities is a physical rule of the Digital World, they are "Immortal Program" and no Digimon can challenge that... No one except Jesmon that can use OS Generics even in base form, he is able to go beyond the laws of the world and can harm even God with his blades
6) If Jesmon harm Ogudomon using OS Generics, this will create some form of contradiction that will affect the Digicore and they may finally be able to defeat Ogudomon
7) Jesmon is going to attack Ogudomon, but a floating Diablomon appeared. Jesmon is surprised because Diablomon can't fly. Diablomon was just a puppet from Lucemon, who says that he's God now and even Ogudomon is only a part of his body, he'll use this power to destroy and create the world. Lucemon commands some Diablomon to fuse to create a weapon and attack Gankomon with this, however Jesmon jumps to take the attack by himself and save Gankoomon
8) In the past, when Lucemon was still in God's Realm, Kernel, he asked God, Yggdrasil, the World System itself to remove the Fighting Instinct from the Digicores of every Digimon. Lucemon hopes that this will end the fights in the world and start a new age of peace. However Yggdrasil didn't agree with the idea. Lucemon thinks that the Fight Instinct is a curse to every Digimon, and rebels against Yggdrasil. The result is that Lucemon falls to the Dark Area, the cocytus, and becomes a Demon Lord. However, even after this, Lucemon still thinks that his idea is the right thing to do. In fact, it's said that he and Jesmon shares the same ideal, of creating a new peaceful world.
9) Jesmon lost consciousness due to excessive pain, but is saved by Gankomon. Gankoomon offers his own X-Antibody to save Jesmon, the light of evolution envelops Jesmon's body, he evolved into Jesmon GX whose power is beyond the X-Antibody.
10) Jesmon GX 's light cures everyone these, even the fallen Royal Knights. Ogudomon X tries to attack Jesmon GX, but he's using OS Generics and is now beyond the world, damage can't be attributed to Jesmon now. Jesmon GX uses his ultimate more, Knights' Intruder using everyone's power to finally defeat Ogudomon X
11) After Ogudomon X is defeated the world is restored and the portals to the dark area starts to fade, some lights are emitted by Ogudomon X body. Most of them went to the Dark Area, but a small light was still there to create a Digitama
12) Yggdrasil sent a e-mail to the Royal Knigths saying that the Old and New DW are going to be fused. Jesmon thinks that this may cause a Digital Hazard and reactive the Project Ark, but it's said that the tames found a solution for that
13) Jesmon is going to travel around the world without the help of Gankoomon, he's taking the Digitama. Jesmon jokes with the idea that the Digimon that will be born from this DIgitama may be a new Royal Knight and him may be his master
