Scarlet Nexus has quite simple mechanics for a JRPG, but what it lacks in gameplay is amply balanced in terms of lore and enemy design. Because the antagonists of Scarlet Nexus, called The Others, could easily join the roster of creatures of a never-released Silent Hill game.
Every creature is a chaotic mix of random items, such as vases, and human parts, especially female legs. The elements are combined together in the most grotesque and surreal way, creating figure that could be part of a Dalí or De Chirico’s painting. In fact, the creatures are created by the modern Japanese artist Masakazu Yamashiro to convey the most alien-looking aesthetic.
While many Others show truly interesting concepts, the most disturbing and brilliant design is always Dominus Circus. One of the last bosses of the main story, the creature will suddenly appear in a giant labyrinth inside the mind of the main antagonist. The monster never appeared before, and only a brief cutscene before the battle provides a barebone background of its past. The only provided information is that Dominus Circus is a immortal Other that was never defeated, a boogeymen for all the soldiers in Scarlet Nexus’ world. And soon after this cutscene, the player should be ready to face the terrifying creature.
The introduction of Dominus Circus is a disturbing surprise. In the beginning, the boss appears only as a sort of classic ghost, a humanoid figure covered under a white shroud. Then, after starting to rotate, the creature will reveal multiple human legs on a monocycle. But only after reversing upside-down, the real monster is revealed: a complex humanoid architecture kept together by thin horse legs. According to Masakazu, Dominus Circus is the climax of the Others’ anatomy, a creature so alien and bizarre to represent the ultimate Other. And from this apex symbolism comes the name “Dominus,” a being almost looking like a disturbing pagan god. The “Circus” part of the name is even more evident, since many details of the design are inspired by the circus, from the umbrella remembering a tent, to the monocycle of the upside-down creatures and the elephant head.
To have a glimpse of the complex and disturbing design of Dominus Circus, you can have a look at the creepy intro in the video below.
The battle against Dominus Circus is one of the hardest of the entire game, especially because it will challenge your memory in 4 long stages. In fact, each phase needs a different approach, and the specific use of supporting characters. This is because, in Scarlet Nexus, connecting with secondary characters unlocks special abilities, including hyper velocity to slow time, telekinesis, or teleportation. The correct use of different powers is necessary to overcome the main obstacle of each stage of this long and complex battle.

During the first stage, Dominus Circus wields a big umbrella as main weapon. With this bizarre spear, the creature looks even more whacky. However, regardless of the appearance, this is probably the most challenging form. In fact, the umbrella will not only completely shield the boss from frontal damages, but will also erupt a water jet that inflicts heavy damages while also knocking the characters down. Moreover, the rotating lower body can also become a deadly drill that the boss uses to charge at the characters to inflict huge damages. And if this was not enough, Dominus Circus can also summon a gigantic water storm, so gorgeous to see as deadly to experience. Using quick skills to jump behind its back, bypassing the umbrella shield, is crucial to kill the first phase.

After each form is defeated, for a brief instant, the small ghost-like figure on the monocycle will appear, completely harmless. Then, it will fall on the ground, disappearing below, just in time for a new dangerous form to remerge.
For the second stage, Dominus Circus has no weapon, but instead it proudly wears a disturbing elephant head. As you can expect, this is the deadly weapon of the second stage. From the trunk, the boss can shoot different kinds of projectiles, including oil. Moreover, Dominus Circus can also summon a thick mist, which completely hides the creature. Using the clairvoyant skill is essential to counter this move and see through the mist. The second stage is very disturbing and intimidating, but luckily less challenging than the first one.
For the third stage, Dominus Circus will be again headless. However, this time, instead of an umbrella, the boss wields a disturbing sword, which looks like made of a combination between a seashell and multiple human arms twisted together. If the other forms are creepy, just looking at how this fleshy sword bounces in its hand is pure nightmare inducing. During this stage, Dominus Circus shows, as expected, dangerous melee combos, which can easily and quickly kill a character. More unexpectedly, the sword can also throw wind-waves, also working very well as a distance weapon. With a good timing while dodging and a balanced use of powers, this stage is not so difficult to overcome.

Now that the 3 main forms are defeated, it only misses the last stage, in which Dominus Circus will combine all the previous weapons and attacks. Yes, you read right, every move and ability will show off in the final stage. So the elephant head to shoot projectiles and create mist, the tricky umbrella to shield from frontal attacks, and the deadly sword, everything packed together in a complex battle that will test your memory and reaction times. Once the combined form is defeated, after a stylish execution, Dominus Circus will be finally and truly dead.

Scarlet Nexus shows since the beginning a set of very creepy and disturbing creatures, but is only with the long and complex battle against Dominus Circus that it clearly shows its climax.
