Sephiroth, a distinguished 1st class SOLDIER, was between 1977 and 1982 as a product of Professor Hojo's Project S. Injected with Jenova's cells during gestation, he emerged as a symbol of Shinra's might. Sephiroth's persona was meticulously crafted, adorned with fabricated achievements, positioning him as a celebrated war hero even before engaging in actual combat. His prominence served as the cornerstone of Shinra's recruitment efforts, enticing aspiring soldiers into the SOLDIER program.
