Sephiroth

Sephiroth (セフィロス) is the primary antagonist in Final Fantasy VII and its extended universe. Once a celebrated hero and the most renowned member of the Shinra Corporation's elite SOLDIER program, Sephiroth is characterized by his long silver hair, green cat-like eyes, and a black coat, wielding the iconic Masamune katana. His descent into villainy stems from the discovery that he was a product of experimentation, infused with cells from the extraterrestrial entity Jenova. Driven by this revelation, Sephiroth seeks to destroy the planet with Meteor and absorb its Lifestream to become a god. He is a recurring nemesis of protagonist Cloud Strife and a popular, iconic villain in the Final Fantasy series. His distinctive appearance, name, and theme music are highly praised by fans, and he has appeared in numerous spin-off titles.
