The narrative centers on the eponymous hero, a genetically modified super‑soldier born from Dr. Von Reichter"s sinister trials. In reality, Von Reichter was a former Nazi who carried out brutal experiments during World War II. After the war, he fled to South America and continued his work, culminating in the birth of the "Cybers," among whom Cybersix emerged. Yet, because the Cybers displayed free will at a very young age—an unwanted feature—Von Reichter eradicated every one of them to avert revolt.
Driven by a quest for the ultimate warrior, he altered human DNA to forge superior fighters. The Cybers were his flagship, yet their sentience threatened rebellion.
Today, Cybersix survived those purges and now adopts the name "Adrian Seidelman," living a low‑profile existence. She discovers that her continued life hinges on a unique chemical concoction devised by Von Reichter, compelling her to track down the "Technos," a newer line of super‑soldiers he engineered. In doing so, she inadvertently assumes the role of a guardian, defending humanity from Von Reichter"s malevolent inventions and schemes.
