Introduction, Facts, and Information
Within the first hour of playing Stellar Blade, I found myself asking: Are the names Adam and Eve intentional, or are they just a coincidence? This curiosity grew even stronger after completing the three endings—not just because of the narrative, but because of a particular detail: the background imagery of the Mother Sphere.
In two of the endings where Adam unites with Eve, we see airships arriving on Earth when Eve communicates with the Mother Sphere. These airships appear just as if a new 8th Airborne Squad has been deployed.

- There is something called the “EVE PROTOCOL,” created by the Mother Sphere.
- The Mother Sphere’s goal is to create a new version of mankind. This is the core motive driving the entire game.
- Seven airborne squads were deployed to Earth, with Eve’s squad being the seventh.
- Raven was part of the second Airborne Squad, and in her final cutscene, we see her sword engraved with the word “EVE.”
- Raven’s words during her final scene are critical.
- The Mother Sphere’s background imagery, words, and atmosphere in all three endings carry significant meaning.
The Core of the Theory
From these details, and considering other in-game information like the databanks, I’ve developed the following theory: Eve wasn’t the only “Eve.”
The publicly known reason for deploying the airborne squads was to defeat the elder Naytiba and free Earth. However, the real plan was to create the perfect Android—an inhabitant to replace mankind on Earth.
In each deployment, while many fighters were sent, only one Eve existed in each squad. This Eve represented a new design from the Mother Sphere, sent to Earth to be tested. The Mother Sphere observed each version and made improvements—think of it like how AI is continuously refined through training (similar to OpenAI feeding data to models like ChatGPT).
From the in-game clues, we can infer that Raven, who was part of the second Airborne Squad, was an earlier version of Eve. This explains why Raven envied Eve, which is made clear when she angrily exclaims, “Why! Why did he choose you over me?”
EVE Protocol: The Ultimate Success
The Mother Sphere’s goal was to perfect Eve, unit after unit, test after test, version after version.
In the endings where Eve and Adam unite, we see an 8th Airborne Squad arriving on Earth. This squad looks like an evolved replica—stronger, more refined. It’s clear that the Mother Sphere used the data from Eve’s journey to improve these new androids.
The arrival of this 8th squad signifies a larger objective: to erase all life on Earth and establish a new android population. That’s why, after the Eve-Adam union, the Mother Sphere tells Eve that the outcome was expected. However, she also refers to the “bad choice” that occurred—namely, the union of Adam and Eve. This suggests that while the union was necessary for data collection, it wasn’t the desired end-state
On the other hand, in the ending where Adam dies, the Mother Sphere never mentions a bad choice. This is because in that moment, Eve rejects Adam’s offer of unity, choosing instead to act of her own free will. This marks a turning point where Eve no longer wants to be used as a tool by any side. She seeks autonomy and the ability to make her own decisions—a quality that reminds us of humankind itself, the very species responsible for wars, environmental damage, and artificial diseases.
Presumably the colony after Eve and Lily get on the ship - Return To Colony EndingThis is the true success of the EVE Protocol: to create a production-ready android capable of free will and, ultimately, replacing humankind. At the same time, the threat posed by Raphael Marks is neutralized, which is why the Mother Sphere sends a ship to retrieve Eve and Lily, inviting them back to the colony.
A Win for the Mother Sphere! But Not Without Uncertainty..
The Mother Sphere achieves victory regardless of the ending. Whether through Eve gaining free will or through her union with Adam, the protocol’s purpose is fulfilled. The Earth is freed from the elder Naytiba, and Eve’s journey provides invaluable data. If Eve gains autonomy, the Mother Sphere still wins by creating a self-aware being capable of decisions. If Eve unites with Adam, the Mother Sphere can use that unity to refine the design further.
However, there’s one potential disruptor to this plan: Eve herself—or perhaps Raphael Marks. We don’t know the full ramifications of Eve and Adam’s union. Did Adam vanish? Was he absorbed into Eve, both physically and mentally? Or did their unity create something entirely new?
Looking Ahead
I believe we’ll see answers to these questions in part 2 or DLC. The union of Adam and Eve could lead to unpredictable consequences, and we don’t yet know if the Mother Sphere’s control is truly secure. Eve’s journey may not be over, and the future holds many uncertainties.
