Originally founded with the purpose to create an opposing force to the growing alliances of mythologies, the Khaos Brigade was built as a cooperation between the Fallen Angel Satanael and the Wizards of Oz . At some point, it was handed to Ophis, the Dragon God of Infinity, who had the sole purpose of removing the Great Red, one of the most powerful Dragons in existence known as the True Dragon, out of the Dimensional Gap.
The Khaos Brigade first appeared in Volume 4, introducing themselves to the world and attacking the leaders of the Christian religion's Three Factions. Shortly after that, the Khaos Brigade began to start many terrorist attacks, such as attacking the VIPs during Rias' Rating Game against Diodora, kidnapping the Youkai leader, Yasaka, and committing many other atrocious acts.
In Volume 11, the Hero Faction betrayed their leader Ophis after Cao Cao, the leader of the Hero Faction, sided with Hades, the God from the Realm of the Dead, and used Samael to steal most of her powers under the intention of creating another Ophis. This has resulted in the latter remaining in a presumed powerless state. However, Ophis released her powers in the form of snakes before Cao Cao came to steal her powers. As such, Ophis did not lose most of her powers.
As of Volume 12, the Khaos Brigade's two largest factions were greatly weakened by the loss of their leaders and various members. This led Azazel into speculating that the other factions of Khaos Brigade that had been lurking in the shadows, would soon arise and take action. In Volume 14, Azazel revealed that there was someone who was trying to unify the remnants of the Old Satan Faction, Hero Faction, and Magician Faction.
In Volume 16, during the Vampire Civil War, it is revealed that the Son of the Original Lucifer, Rizevim Livan Lucifer, became the new leader of the Khaos Brigade. He planned to reach the other world by having Apocalyptic Beast 666 (Trihexa) fight the Apocalypse Dragon Great Red. A new faction called Qlippoth was created and this faction planned to use the Sephiroth Graal to revive the Evil Dragons who are feared by every mythology.
In Volume 20, 666 was successfully awakened when Rizevim after death, used his soul to awaken the beast and it, along with the Evil Dragons Apophis and Aži Dahāka who had betrayed Rizevim taking control of Qlippoth, set out to attack the mythologies. In Volume 21, the trio of 666 and the two Evil Dragon leaders caused great destruction, almost completely decimating Heaven, Grigori, and Asgard, killing many Gods in the process and soon after, began attacking Europe and Japan in the Human World. The Khaos Brigade officially came to an end when Qlippoth was finally defeated in the the Evil Dragon War.
The Khaos Brigade was a loose knit association of various supernatural beings who were dissatisfied by the growing alliance of various mythological powers and sought to plunge the world into chaos. Formerly led by Ophis, who served as a figurehead.
The Old Satan Faction (旧魔王派, KyūmaŌ-ha) was the largest faction of the Khaos Brigade which consisted of the Devils who were descendants of the original Satans: Beelzebub, Leviathan and Asmodeus such as Shalba Beelzebub, Katerea Leviathan and Creuserey Asmodeus. This faction officially disbanded in Volume 12.
Qlippoth (クリフォト, Kurifoto) was an organization that was under Rizevim Livan Lucifer, which had the main purpose to invade other world of ExE using the Evil Dragons. For that goal, they sought to defeat the Great Red, which protects the Dimensional Gap by reviving the legendary beast, 666 (Trihexa).
Hidden Khaos Brigade Edit
Hidden Khaos Brigade (隠れ禍の団, Hido~un Kaosu Burigēto) is a collection of the remnants of the defunct Khaos Brigade. Khaos Brigade and it's successor group Qlippoth couldn’t function normally due to their valuable charismatic figures — Shalba Beelzebub, Cao Cao and Rizevim Livan Lucifer being defeated by Team DxD. However, there are still a considerable amount of people that took over organization’s ideology or devoted themselves to it, and even now their numbers are increasing little by little. Hidden Khaos Brigade spies exist in every mythology and nearly every place affiliated with Team DxD, including Kuoh Town, and even the Gremory and Sitri households. Members of the Hidden Khaos Brigade were leaking information on Team DxD to the Alliance of Hell, including information on the barrier that surrounds Kuoh Town, which all factions cooperated to create.
The Vali Team (ヴァーリチーム, VarĪ Chīmu) was a special team of the Khaos Brigade led by Vali Lucifer, the descendant of Lucifer and the keeper of Albion, the White Dragon Emperor and the arch-rival of Ddraig, the Red Dragon Emperor. The Vali Team was not connected to any of the factions of the Khaos Brigade and acted independently.
The Hero Faction (英雄派, Eiyū-ha) was the second-largest faction of the Khaos Brigade led by Cao Cao, the descendant of Cao Cao from the Chinese novel Romance of the Three Kingdoms and the one who betrayed Ophis. It was a faction of the Khaos Brigade that was allied with Hades, the Greek God from the Realm of the Dead, and it was also one of the most dangerous factions of the Khaos Brigade due to its members being Sacred Gear, Holy/Demon Sword, and Longinus wielders. This faction officially disbanded in Volume 12.
- Qlippoth was named after the same name of the representation of evil or impure spiritual forces in Jewish mysticism, the polar opposites of the holy Sefirot.
