Yojimbo is a boss in Final Fantasy X. He is an aeon summoned by Lady Ginnem, a summoner who was killed in the Cavern of the Stolen Fayth under Lulu's guardianship. He can also be summoned by Belgemine at Remiem Temple as a means of training Yuna. His first defeat in Remiem will award the player with Shadow Gem x8, while subsequent defeats award Power Sphere x10. Yojimbo is also fought inside Sin, when the final boss possesses Yuna's Yojimbo.
Yojimbo usually attacks using his dog Daigoro, though he may occasionally attack with Kozuka and Wakizashi when low on HP. Yojimbo's Overdrive charges on his turn and whenever he is attacked. When full, he will unleash Zanmato, which inflicts 9,999 points of damage on all party members. The player can avoid this by sacrificing an aeon.
The player can defeat Yojimbo by inflicting the Doom status on him. This can be done either by Kimahri using the Ronso Rage Doom, which can be learned from the Ghosts inhabiting the cavern, or by using a Candle of Life. Yojimbo will then be defeated within five turns. This strategy only works for the encounter in the Cavern of the Stolen Fayth.
The music for the battle in the Cavern of the Stolen Fayth is "Lulu's Theme."
