Rod and Uri's father

Mr. Reiss is the biological father of Rod Reiss and Uri Reiss, and the grandfather of Frieda Reiss and Historia Reiss. He is also one of the previous Reiss family members who possessed the Coordinate.

Appearance
Mr. Reiss was a middle-aged man, with neck length hair that curled at the ends, and a receding hairline. He had a moustache, as well as a short beard that went up and merged with his hairline. Like those before him, who inherited the First King's will, he had vacant eyes.

History
When he was the wielder of the Coordinate, he refused to rid the world of Titans. Rod and Uri Reiss pleaded with him on multiple occasions. So much so, that Rod was locked behind bars because of his repeated attempts.

Eventually it came time to pass on the coordinate to one of his sons. Like former wielders of the coordinate, he was chained to the ground so that the next inheritor could eat him after transforming into a Titan.

Abilities
Like former Coordinate users after him, he has:


 * Memory Manipulation: This ability is related to the "Invincible Power," the Coordinate. He could manipulate the memories of humans if he wanted.

Titan Shifting
Though his Titan form is never shown, he possesses the same regular abilities as Titans and other Titan Shifters.
 * Regeneration: Like all Titans, he possessed healing abilities.
 * Enhanced Strength: All Titan shifters have enhanced strength compared to not just humans, but Titans as well.
 * "Invincible Power": Briefly mentioned by Rod, it has the potential to exterminate all the Titans. It's unknown if he ever mastered this ability, but all Reiss members that take part in the succession ceremony gain this ability.
