MOMO Mizrahi

MOMO Mizrahi is a playable character in the Xenosaga series.

History
MOMO is a prototype 100-series Realian. Her name stands for Multiple Observative Mimetic Organicus. She was designed to observe and contact the gnosis. MOMO was created by Joachim Mizrahi and was designed to resemble his dead daughter Sakura. She views him as her father, and Joachim's wife, Juli as her mother. She was created at Proto Merkabah.

At the start of the game MOMO is held captive by the U-TIC Organization within the base Pleroma. Margulis visits her in a cell, seeking to contact what he claims to be the man hidden inside of her. MOMO is the only source of the Y-Data, important data from Joachim Mizrahi. Ziggurat 8 is hired by the Special Committee for Close Encounters to rescue MOMO from Pleroma. He is able to sneak inside and release her from her cell. While not a fighter, MOMO supports him in battle as a healer and spell user. She is also able to cause problems for the sensors on enemy A.G.W.S. by using the Hilbert Effect. Finding his real name to be too formal, MOMO nicknames him Ziggy, a name that sticks throughout the remainder of the series. While they are confronted by Margulis, the two of them are eventually able to escape from Pleroma on a shuttle.

Escaping from U-TIC, MOMO handles piloting for their craft as they enter hyperspace. MOMO is disappointed to hear that they won't be traveling to the S.O.C.E. Committee headquarters where her mother is, but rather to Second Miltia. When U-TIC approaches, they try and fight them off and join up with the passenger craft Elsa. They board the ship, meeting Shion and the others and MOMO helps in fighting off the enemy. They reveal that they are heading to Second Miltia, the same place as Shion and the others.

MOMO remains aboard the Elsa as it travels to the Dock Colony, then is encompassed by the Cathedral Ship. When she and the others are recovered by the Durandal she meets Junior, but gets upset upon hearing him refer to her "ather as a lunatic. Shion and KOS-MOS come to see her in the Durandal Park to help cheer her up. Thinking they may split up from each other in the near future, Junior provides MOMO with a bracelet keepsake. When the Kukai Foundation is framed by the U-TIC Organization for destroying the Woglinde, MOMO is arrested along with the other party members. When the party heads into the Encephalon within KOS-MOS to try and prove their innocence, MOMO is brought along with Ziggy and Junior to the streets of Old Miltia. They eventually come across the tower Labyrinthos, seeing her father speaking atop the tower then falling to his death, upsetting her greatly.

When a massive amount of gnosis start appearing Junior orders the civilians to depart the Kukai Foundation and get on the Durandal. MOMO stays behind to help the wounded but is kidnapped by Albedo, who makes himself appear as if he were her father. Albedo brings her to the Song of Nephilim where he frightens her considerably, first by killing a Kirschwasser, then by ripping off his arm and decapitating his own head. Realizing that MOMO knows Junior, Albedo becomes pleased, but also more maniacal and MOMO passes out. Junior and the others come to rescue her and Albedo is able to escape due to the Blue Testament showing up. When Albedo revives Proto Merkabah, MOMO recognizes it as the place of her birth and further information about her creation is found out when the party travels through it. As the game ends MOMO is aboard the Elsa as it descends into Second Miltia.
