SARAH
Sarah is a central character within the Gundam Build sub-franchise, existing as a sentient electronic lifeform known as an EL-Diver. Though several characters bear the name throughout Gundam history, the Build Divers iteration represents a landmark evolution in the series' exploration of AI and digital consciousness.
Cronologia
Biografia
Sarah is a soft-spoken and mysterious girl who first appeared in Gunpla Battle Nexus Online (GBN), where she encountered the protagonist Riku Mikami and his friends. Unlike typical players, Sarah is an EL-Diver—an electronic lifeform born entirely from the digital data of the game.
She possesses an extraordinary level of intuition, allowing her to sense the 'feelings' and 'love' that builders invest into their Gunpla. This connection makes her an invaluable member of the Build Divers force, often accompanying Riku in his cockpit during intense battles or hitching a ride in Momoka's Momokapool.
Despite her gentle nature, Sarah's existence initially posed a grave threat to the GBN environment. As she gained emotions and memories, her data expansion caused increasingly frequent system bugs, leading the Game Master to view her as a digital anomaly that needed to be erased. However, through the efforts of the Build Divers, she was saved and her consciousness was transferred into a unique Gunpla body—the Mobile Doll Sarah. This transition allowed her to transition between the virtual world and the real world, where she continues to advocate for the coexistence of humans and digital entities within the Gundam multiverse.
Storia
The origins of Sarah are rooted in a phenomenon theorized by the administrator Ms. Tori. Every time a Gunpla is scanned and transmitted within the GBN system, a tiny fraction of data—approximately one-millionth of the total—is added as excess. This data represents the feelings and passion of the Divers themselves. Over time, this collective emotional data converged to create Sarah.
While she was the first EL-Diver to be officially recognized by the GBN administration, she was not the first to exist; the entity known as Eve preceded her and actually sacrificed herself to absorb bugs that would have otherwise shortened Sarah's lifespan. In the Universal Century timeline, another Sarah (Sarah Zabiarov) serves as a tragic Newtype pilot for the Titans.
Recruited by the manipulative Paptimus Scirocco, her backstory is defined by her fanatical loyalty and her struggle with her conscience while piloting heavy mobile suits like the Bolinoak Sammahn. Across the After War timeline, Sara Tyrell's history begins as a strategic operator for the Vulture ship Freeden, where she established herself as a vital military mind during the post-apocalyptic conflicts on Earth.
Evoluzione
The character of Sarah has undergone a significant physical and conceptual evolution. She began as a 'ghost in the machine,' a digital anomaly causing instability within GBN. Her initial growth was purely emotional, but as her presence threatened the game's survival, her status shifted from a mystery to a focal point of a global conflict between the Build Divers and the game's administrators.
This culminated in her transformation from a purely digital entity into a 'Mobile Doll,' a physical Gunpla body that bridged the gap between the virtual and real worlds. In later series like Re:RISE and Metaverse, Sarah has evolved further into a leadership role. No longer just a girl in need of protection, she acts as a mentor and a symbol of peace for other EL-Divers. Similarly, in the broader franchise context, the 40th anniversary of Zeta Gundam in 2025 has seen a re-evaluation of the original Sarah Zabiarov, moving her from a side antagonist to a featured icon of the Titans' tragic history, highlighted by new 'What-If' scenarios in modern gaming titles that explore her potential defection.
Da Collezione
For collectors, Sarah is most famous for the High Grade (HG) 1/144 Mobile Doll Sarah, a unique kit that allows builders to swap between her 'MS Mode' and her 'Diver Look.' This kit is highly sought after for its transformational gimmick and its representation of the character's real-world body. Another notable release is the HGPG 1/144 Petit'gguy Chara'gguy Sarah, which reimagines her in the adorable Petit'gguy format.
Collectors of the Universal Century Sarah Zabiarov typically target the Gundam Girls Generation (GGG) line of high-quality PVC statues produced by MegaHouse. The 2025 commemorative HG 1/144 Bolinoak Sammahn is considered a 'grail' for many, as it finally provides an updated, modern engineering version of her signature mobile suit for her 40th anniversary. Value trends show a steady increase in demand for EL-Diver-related figures, especially following their reappearance in the Gundam Build Metaverse project, which revitalized interest in Sarah's digital-to-physical journey.
Despite being a sentient AI, Sarah is seen participating in social events like the Beargguy Festival, where Momoka was seen feeding her.
