Item from Attack on Titan by Hajime Isayama
The progenitor of all Titans. Can control all Eldians, alter memories, command Pure Titans. The most powerful force in the world — and a cage for whoever holds it.
The Founding Titan is not merely the strongest of the Nine — it is the source. Its power flows through the Paths to touch every Subject of Ymir alive, granting its wielder the ability to alter Eldian biology, rewrite memories wholesale, command every Pure Titan in existence, and reshape the very bodies of an entire race. The catch: it only works at full power for someone of Royal Blood. When a non-royal inheritor touches someone of Royal Blood, the power activates — but so does the will of the First King, who used the Founding Titan to build the walls, erase his people's memories, and create a prison disguised as paradise. Eren Yeager broke this cycle by convincing Ymir Fritz herself — the original Titan, enslaved for two thousand years — to lend him the power. The Founding Titan is freedom and slavery in the same body. It always has been.
Also known as: the Founding Titan, the Coordinate power, the Progenitor Titan
