Chaos chose Soma Cruz to become the next Dark Lord due to his inheritance of Dracula's soul. Realizing this, Soma set off to somehow enter the Chaotic Realm and fight his own fate, not without first measuring strengths with Julius Belmont and making him promise that in case evil finally overcame him, he should kill him.
Despite all of Chaos's efforts, Soma eventually felled the eldritch personification of darkness, thus finally making the castle to exit the eclipse it was trapped in, while crumbling and disappearing from this world at the same time.
As Soma slowly descended back to earth as if he was waking up from a dream, in his mind he could hear the voices of his friends, Yoko, Hammer, Julius, and Genya, congratulating him and bidding him farewell.
As Soma enters Chaos's room, the entity starts the battle by stealing all of his collected souls (save for Ability Souls) and fights him in the form of a giant wheel portraying three statues on it, each which unleashes a different attack:
- The statue holding the red orb retains all of Soma's Bullet Souls and shoots out three crystals.
- The statue holding the blue orb retains all of Soma's Guardian Souls and transforms into a rushing gargoyle.
- The statue holding the yellow orb retains all of Soma's Enchanted Souls and summons a targeting reticle to lock-on to him and steal his MP.
Destroying each statue will release all of its captured souls back to Soma.
Once all three statues are destroyed, Chaos transforms into its true form: a black orb in the middle of the room which features black prominences in such a fashion that it resembles a dark sun. Its only weak spot is this very core. The core's attacks consist of summoning needles and homing projectiles.
A serpent comprised of bones, similar to a Skeledragon, incessantly slithers around the room, dealing massive damage if Soma comes into contact with it (the serpent is also immune to any form of attack or damage). Moreover, four eye-resembling objects are situated on each corner, which occasionally release small black orbs, although these balls can be deflected by attacking them. Defeating the four eyes will cause them to burn away and will decrease the defensive stat of the main core.
- Each part of Chaos (three colored orbs, eyes, and the black sun) has 3,000 HP.
- Chaos's core defense is reduced for every destroyed eye.
- Chaos is one of the three enemies in Aria of Sorrow that does not drop any souls, along with Julius and Graham.
- In Dracula X Chronicles, during the final battle, when Dracula enters his third form, a large eye in a black void can be seen through a large, cracked hole in the background. It is possible that the eye belongs to Chaos, signifying Dracula's usage of his full power. This is pure speculation, however.
- According to the novel Akumajō Dracula: Kabuchi no Tsuisoukyoku, Olrox is looking to control both Chaos and humanity.
- Chaos originally had an enemy list entry which showed a picture not used in the game. However, the creators took the entry out of the game, making it unable to get the entry without hacking.
- ↑ "Kabuchi no Tsuisoukyoku" fan translation:
- "The castle is the symbol of the chaos within humans and as long as people exist, it will not be completely sealed."
- "As I've said, I would equally gain control over the human world and the source of Dracula's power, chaos. I do not intend to obey someone else's mind aside from my own. That includes you who were born out of chaos."
- "If I could control the even heart that is the root of humans... Would the chaos that is born from them no longer exist? I have no interest in tranquility but it could be fun to challenge that."
- ↑ Fan translation by Shiroi Koumori: "The magic I received from the castle will not be used to bind humans to chaos and other similar things. I would like to equally gain control over both humans and chaos."
