Zeke

Zeke is a very intelligent and curious person.

Zeke is a mysterious Titan Shifter (the inheritor of the Beast Titan) that was first seen within Wall Rose during its supposed breach, and was responsible for transforming the people of Ragako into Titans. He acts as a military leader of the warriors of the Hometown and serves as one of the current primary antagonists of the series.

Zeke has been revealed to be the son of Grisha Yeager (Eren's father) and Dina Fritz, which means he has royal blood. He reported his parents and the Eldia Restorationists to the Marley government.

Although he initially seemed to have allegiance to Marley, he actually turned his parents in to gain Marleyan authorities' sympathy and secure his status as a loyal warrior. His true goal was to free the Eldian people, and he intended to carry out the Euthanasia plan, using the Founding Titan's power (in Eren's hands) to render all Subjects of Ymir sterile.
