Fritz (Figurehead)

Fritz (フリッツ) is the king, the person of officially the highest rank in the society within the Walls. However in reality he is just a puppet king who acts as a substitute for Rod Reiss, the real king.

The Uprising arc
Even though he has been talked about a lot before, his first appearance is during a conference with four other people, among them a member of the Military Police Brigade. Fritz doesn't wear his crown during this conference, but instead leaves it on the table beside him along with a bottle of alcohol.

He later appears again asking Erwin if he has any last words before his execution. However after the military rebels against him and the nobles, he is called a "senile old fool" by one of the nobles and appears to be confused and unaware of the current situation.

Trivia

 * His first name is still unknown. He is only referred to as "the king from the Fritz royal family" (フリッツ王家).
