When the surviving Knights of the Round attempt to remove Lelouch from power, Suzaku easily defeats them with his new "Lancelot Albion". He also assists in taking the U.F.N. leaders hostage. During the battle against Schneizel and the Black Knights, he joins Lelouch in boarding the "Damocles", holding Gino off while Lelouch goes ahead. Suzaku comes out victorious, but Gino's last attack opens the shields and allows Kallen to take over. Kallen manages to land a fatal blow on the "Lancelot" while his last attack disables her Knightmare. The "Lancelot" explodes shortly after Kallen is rescued by Gino. Despite being nearly defeated in the duel itself, Suzaku is the one to attain the goal of the fight: to prevent Kallen from going after Lelouch, thus winning him the final victory and keeping the Zero Requiem on track.
