Cloud Strife ( Kuraudo Sutoraifu?) is the protagonist of Square's (now known as Square Enix) role-playing game Final Fantasy VII and several of its sequels and spin-offs. His appearance is marked by spiky blonde hair, vivid greenish-blue eyes (a distinguishing feature of SOLDIER members and a sign of having been exposed to mako energy), dark purple or blue clothing, a spikey, dark grey pauldron on his left shoulder, and his Buster Sword (a sword with a distinctive, oversized blade), which previously belonged to his friend Zack, and the SOLDIER Angeal Hewley, before him. At first, Cloud displays a cold and uncaring demeanor, but he gradually overcomes romantic and psychological problems and adapts to his role as a leader.
