Frieda Reiss is this fascinating, tragic figure in 'Attack on Titan' who doesn’t get enough spotlight, honestly. She’s Historia’s older half-sister and the true heir to the Reiss family, which means she inherited the Founding Titan’s power before Historia did. What’s wild is that Frieda was supposed to be this gentle, kind person—Historia’s memories paint her as almost saintly—but the power of the Titans twisted her. The Founding Titan’s influence, especially under the control of the First King’s ideology, made her passive and resigned to the idea of Eldia’s destruction. It’s heartbreaking because she genuinely cared for Historia but couldn’t act against the King’s will.
Her death is one of those pivotal, understated moments in the story. Grisha Yeager kills her to steal the Founding Titan, which sets off the entire conflict with Eren later. The irony is that Frieda, despite her power, was never truly free. She’s a great example of how 'Attack on Titan' explores the weight of legacy and how even the strongest can be shackled by history. I wish we got more flashbacks of her—she’s such a ghostly presence in Historia’s arc, lingering in the background of everything.
