Karl Fritz

Karl Fritz was a man wracked with the guilt of his ancestors. Even before inheriting the Founding Titan, Karl Fritz detested the atrocities committed by the Eldian Empire. This intense guilt would lead him to conspire with the Tybur family to weaken Eldia enough for Marley, a nation long oppressed by Eldia, to conquer it and take back their land. Fritz held the belief that the world would have been better off if Titans and Eldians never existed and he considered his people to be sinners. He believed that if the world decided to exterminate the Eldians, because the Eldians' sins are too heavy to be atoned for, it should be accepted. Despite this, Karl Fritz and his successors still wish for their people to live in peace and happiness. So he created a "paradise" inside the Walls for them to live in, erasing his people's memories to make them ignorant and blissful, before the nations of the world would inevitably invade. He was fierce at defending the peace inside the Walls and feared the minority bloodlines he could not control; when the Ackerman family and the Azumabito branch clan refused to be silenced, he betrayed them and ordered their extermination.

Power of the Titans
Little is known about his abilities as a Titan, except for the fact that he had enough control to retain his intelligence while transformed; since he was seen surrounded by a crowd of people without attacking them, and without any of those people trying to flee. Karl Fritz held the Power of the Titans, specifically that of the Founding Titan, and displayed many abilities related to that power; some of them at a rather advanced level. His powers included: * Titan Creation: Karl Fritz used this power to transform Eldians into countless Colossus Titans. * Titan Control: He used this power to control the Colossus Titans to build the Walls, by making them harden their bodies and confine themselves into the resulting structures. * Memory Manipulation: He was capable of manipulating the memories of Subjects of Ymir. Other ethnicities, such as the Ackermans, the Asian clan, and the noble families (who belonged to various ethnicities that were not Subjects of Ymir), were unaffected. * Memory Inheriting: He was able to pass down his memories to an unknown member of the Reiss family after dying, making them the inheritor of the lost memories of mankind. This also happened with all of the other inheritors, who inherited the memories of Karl Fritz and the inheritors themselves. However, they and all their subsequent heirs also inherited his belief that a world ruled by Titans would be "true peace." This influence is so strong that even people that wanted to stop the Titans changed their minds when they received the power, deciding not to make a move and refusing to reveal the reason, even to their own families.
