Sephiroth (Final Fantasy VII)

Some bosses need a health bar to scare you. Sephiroth just needs the music to start. The silver hair, the impossibly long sword, the slow walk toward disaster — everything about him tells you the situation has gone terribly wrong. His rivalry with Cloud turns the final confrontation into something much more personal than a standard endgame fight. And when One-Winged Angel kicks in, you know exactly who you're dealing with. Bowser has the mainstream recognition, and Ganondorf has his own legendary rivalry, but Sephiroth makes a serious case for gaming's greatest final-boss presence. Does pure intimidation win the GOAT debate, or does he need more than aura to take the crown?
