Rod and Uri's father

was the father of Rod and Uri Reiss, and the paternal grandfather of Urklyn, Frieda, Dirk, Abel, Florian, and Historia Reiss. He was also one of the previous Reiss family members who possessed the Founding Titan and one of the true kings of the Walls.
== Appearance ==
=== Human form ===
Rod and Uri's father was a middle-aged man with neck-length light hair that curled at the ends and a receding hairline, which his sons would later inherit. He had a mustache as well as a short beard that went up and merged with his hairline. While being affected by the First King's will, he had dark, vacant eyes.
== Personality ==
Although little is known about his personality, some of his actions were seemingly influenced by the will of the First King. He never paid attention to his children's pleas about ridding the world of the Titans, even going so far as to lock up his son Rod due to his insistence.
== History ==
He inherited the Founding Titan and the position of king during the Reiss family succession ritual from an unknown Reiss. While he was the wielder of the Founding Titan, he refused to rid the world of Titans, as he inherited the will of the First King who saw a rule by them as true peace. His sons Rod and Uri Reiss pleaded with him on multiple occasions. It was so much so, that Rod was locked behind bars because of his repeated attempts to convince him.
Eventually, it came time to pass on his powers and position to one of his sons. Like former wielders of the Founding Titan, he was chained to the ground so that the next inheritor could eat him after transforming into a Titan and regain human form. Uri volunteered, asking Rod to pray. After the procedure, Rod realized Uri had inherited the same ideology the moment he looked into his eyes, realizing at the same time that Uri had become God.
== Abilities ==
=== Power of the Titans ===
Though his Titan form is never shown, he possessed the same regular abilities as Titans and other inheritors of the power of the Titans.
* Founding Titan: Because of his royal blood, Rod and Uri's father had the full abilities of the Founding Titan and could manipulate the memories of Subjects of Ymir. Rod calls this the "invincible power."
* Regeneration: Like all Titans, he possessed healing abilities, being able to regenerate injuries that would be fatal to humans in minutes.
== People killed ==
* Previous inheritor of the Founding Titan (as a Pure Titan)
