Falco Grice, an Eldian Warrior candidate from Liberio, trains to inherit the Armored Titan to shield Gabi Braun from its 13-year curse. His compassion emerges in acts like aiding wounded enemy soldiers amid the Marley-Mid-East War and soothing traumatized veterans, defying peers who mock his mercy over combat ruthlessness. Formally addressing superiors like "Deputy Chief Braun" to Reiner, he strategically improvises alibis to safeguard Gabi during covert Paradis missions. Reiner pressures him to outperform Gabi in training to spare her the Titan’s fate, driving Falco to sharpen his resolve. Unwittingly entangled in Eren Jaeger’s schemes—posed as the wounded soldier "Kruger"—Falco unknowingly delivers letters enabling Paradis’ assault on Liberio. This manipulation draws him into Eren’s infiltration of Marley, triggering the festival’s devastation of Liberio’s internment zone. Exposed to Zeke Jaeger’s spinal fluid, Falco becomes a Pure Titan during the Battle of Shiganshina. Compelled by Zeke’s command, he attacks Reiner but devours Porco Galliard, inheriting the Jaw Titan. His Titan form manifests avian features—a beak-like jaw and talons—shaped by Zeke’s Beast Titan fluid. Later, flight emerges as a latent ability, reflecting his yearning for freedom, echoed in bird-themed memories and a Beast Titan predecessor’s influence. In the final clash against Eren, Falco leverages his Titan to evacuate allies, grappling with unstable transformations. Motivated by a vow to Reiner to protect Gabi, he prioritizes her safety over confronting Eren directly. Post-war, he aids in eradicating the Titan curse, reversing all Pure Titans to humanity. The epilogue reveals him alongside Gabi tending to Levi Ackerman, confined to a wheelchair from battle injuries. Key bonds include his protective bond with brother Colt, who saves him at Fort Slava, and unrequited feelings for Gabi, whom he consistently shields. His empathy spans enemies, evident when halting Gabi’s assault on Kaya Braus and intercepting Niccolo’s wine-bottle strike meant for her—a act that inadvertently ingests Zeke’s spinal fluid. Falco evolves from a reluctant soldier to the Alliance’s strategic linchpin, reconciling ethics with war’s brutality. His avian Titan traits and flight symbolize bridging divided worlds, embodying liberation and breaking cycles of conflict.
