2,000 years ago, the founder of the Titans, Ymir Fritz, died. Her powers were split into 9 powers, one of them being the Jaws Titan. It was passed down throughout the Eldian empire until the Marley empire took over the world and stole seven of the nine Titans, including the Jaws Titan. 100 years later, it was passed down to Marcel Galliard, an Eldian Warrior cadet living in the Liberio internment zone.
