Dina Fritz

Dina Yeager, neé Fritz, also known as the Smiling Titan, is a supporting antagonist in the anime/manga series Attack on Titan. She returns as a flashback character in the Return to Shiganshina arc, the Marley arc and the War for Paradis arc, mostly as a human. She is an Eldian of Marley, from the city of Liberio, and a member of the royal family of the former Eldian Empire. She is the first wife of Grisha Yeager and the mother of Zeke Yeager, the former stepmother of Eren Yeager, and the Abnormal Pure Titan who killed Grisha's second wife and Eren's mother, Carla, during the invasion of Wall Maria, driving Eren to swear revenge against the Titans. Five years after their first encounter, Eren encounters the Smiling Titan again during his escape from the Armored Titan. She kills Hannes in front of Eren and Mikasa. Eren, who is by now an Intelligent Titan, unknowingly uses the power of the Coordinate against the Smiling Titan, which works thanks to Dina's royal blood, resulting in Dina being devoured by other Pure Titans. Eren and the rest of the Survey Corps witness this as they escape the Armored Titan. The life of this woman-turned-monster had been full of contradiction and tragedy that only ended with her death at the hands of Eren, who, after learning the Titans' origins, loses his hatred for her and Pure Titans in general.
