Showdown at the House of Blue Leaves and presumed Death

After Beatrix Kiddo woke from her four-year long coma, she hungered for revenge on the Deadly Viper Assassination Squad and wanted to kill all of the members within the Squad. Beatrix traveled to Tokyo, Japan, to kill O-Ren Ishii first. While Beatrix was fighting against some of O-Ren's guards and Gogo Yubari at the House of Blue Leaves, O-Ren secretly tipped off the Crazy 88 to arrive and kill Beatrix. Mo battled alongside the Crazy 88 to try to kill Beatrix. He fought the Bride one-on-one three times. He is a more proficient fighter than the rest of the gang, nearly tipping the scales in their favor and holding his own against the Bride for several minutes alone while fighting her on top of a balcony railing. However, Beatrix eventually chops off both of his legs, and he falls into a pond from that second floor balcony and is presumed dead thereafter.
