The Ravens are a squad of genetically engineered super soldiers created under the supervision of the AVALANCHE member Fuhito in Before Crisis -Final Fantasy VII-. Fuhito created this group using data he had gathered on SOLDIER. This organization's main purpose was to serve directly under Fuhito as his enforcers to further complete his plan of "purging the planet". These soldiers are capable of advance fighting skills and are able to heal from fatal wounds at a generally fast rate. A consequence of these new found abilities is that those within the group have lost most of their humanity. Many Ravens are encountered throughout the Before Crisis -Final Fantasy VII- storyline. Other than Essai and Sebastian, two SOLDIERs forcibly mutated, only the Ravens Kanos, Kyneugh, and Tierce are referred to by names.
The first time encountering Ravens is in Episode 5 of Before Crisis -Final Fantasy VII- when the player Turk meets Cloud. The Ravens are sent by Fuhito to obtain a disk of information on SOLDIER from the scientist named Rayleigh. All of her personal guards besides Cloud are killed by Ravens.
The Raven who was sent to retrieve the disk with information on SOLDIER took Rayleigh hostage. The player Turk was ordered to obtain the disk, even at the cost of Rayleigh's life. Cloud, however, got in the way to protect her, allowing AVALANCHE to escape on the train with Rayleigh and the disk. While the player Turk was fighting the first Raven to make an appearance, Cloud boarded the train last minute to try and rescue Rayleigh.
The player Turk manages to get onto the train by taking a shortcut through a center pillar that the train loops around five times. When on the train, the player Turk then encounters several more Ravens. It is noted that the player Turk did not believe their skill was good enough to handle more than two Ravens at a time.
The player separates the train cart that Cloud and Rayleigh were on from the rest to keep AVALANCHE from them as they were severely outnumbered. However, AVALANCHE quickly catches up once their cart comes to a stop. One more Raven assaults Cloud and Rayleigh, which the player Turk defeats with ease. However, when the player Turk stepped outside of the stopped train with Cloud to fight off AVALANCHE, the Raven that the player Turk defeated in the cart Rayleigh was in "sprung back to life" and took the disk from Rayleigh.
