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.
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.
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.
