Sephiroth is one of the main antagonists of the Final Fantasy VII series, created by Tetsuya Nomura. Initially introduced as a celebrated soldier of SOLDIER, he becomes a legendary figure within the Shinra Electric Power Company and is revered for his exceptional combat skills. Sephiroth's story begins after discovering the truth about his origins as a product of an experiment involving Jenova cells, which leads him to question his identity and purpose. His descent into villainy is marked by his quest to reclaim what he believes he lost, including his mother’s legacy and connection to the world, culminating in the catastrophic events of the Nibelheim incident where he destroys the village, inciting the ire of protagonist Cloud Strife. Throughout the original game and its subsequent adaptations, including spin-offs such as Crisis Core: Final Fantasy VII and the Final Fantasy VII Remake, Sephiroth evolves into an iconic figure representing themes of loss, identity, and the struggle against one's destiny. His unmatched prowess in combat, combined with impressive magical abilities, makes him a memorable figure in gaming history. As a quintessential villain, Sephiroth has become synonymous with the word 'antagonist' within video game culture, influencing narratives far beyond his own series.
