Chaos Agency

The Chaos Agency (ケイオス エージェンシー) was a malicious multi-billion dollar organization initially led the evil Sakari and is a major antagonist in Rising Beginnings, Ocean Blue, and Victory Sword.

The organization was created in pursuit of evil and its ultimate goal was to take over the world, beginning with Evershade. To complete his plan, Sakari attempted to transform East City's humans into mutants and brainwash them, however, this brought them into direct conflict with Keiichi's group, leading to their defeat.

However, its legacy continued with Dakera, who relocated to Kingdom Island, planning to use mythical beasts to take over the world instead of mutants and were ultimately defeated by Azure and Crystal. Years later, the newly freed Dakera converted the Agency into a mafia group in the Diaglo region.

It also formed its own mercenary group, The Expendables. Finally, the Chaos Agency was finally defeated for good by Nicki's group after its quest for the Sword of Destiny.

Re:Evershade
Much like the Chaos Agency from the various arcs the manga, the Chaos Agency in Re:Evershade was founded by Sakari and later led by Dakera in an attempt to gain global power. Unlike the previous Chaos Agency, this version also attempts to achieve worldwide recognition and uses super-powered soldiers in their deeds, instead of mutants.

In Rising Beginnings Arc, the Chaos Agency sends a man whom they experimented on to East City, where he caused havoc until being defeated by Kierian's group. Deeming him as a failure, this marked the last time they used mutants for their personal agenda, and also lead them into direct conflict with Kierian. After their defeat in The Beginnings Arc, they are led by Dakera and continue their operations in Kingdom Island. Teaming up with remnants of Division X, the Agency kidnap Chloe and Blane using a brainwashed mythical beast and rig the island with explosives.

When Kierian and Sky Violette arrive on the island, the Agency hunt them down throughout the island. Following a defeat, Kierian and Sky team up with Crys Lee right as civilians are disappearing from the island due to the Agency's attempts to summon a mythical beast. After their defeat on Kingdom Island, the Agency moves to the Diaglo region where Dakera transitions it into a mafia group. Attempting to use the Sword of Destiny to unleash Prometheus, the Chaos Agency was opposed by Kate Fletcher's team where it succeeded in finding the sword but were incinerated by Joseph Johnson.
