Falco Grice, an Eldian Warrior candidate from Marley, trains to inherit the Armored Titan, driven by a determination to spare Gabi Braun from the role’s fatal consequences. His inherent compassion and aversion to conflict clash with his militaristic upbringing, yet he repeatedly proves his courage in battle—most notably by shielding Gabi from gunfire. As Colt Grice’s younger brother, familial loyalty fuels his actions, especially his focus on securing Gabi’s future. During Marley’s war against the Mid-East Allied Forces, Falco confronts Titan warfare’s horrors firsthand while undergoing combat evaluations. A battlefield injury and subsequent rescue by Colt solidify his commitment to safeguarding others. Defying expectations, he risks ridicule to carry a wounded enemy soldier to medical aid, highlighting his unwavering empathy. Exposure to Zeke Yeager’s spinal fluid triggers Falco’s transformation into a Pure Titan, leading him to unintentionally inherit the Jaw Titan from Porco Galliard. This metamorphosis grants him avian traits—a serrated beak, talons, and later wings—tied to Zeke’s Beast Titan lineage. These adaptations enable flight, an unprecedented ability among Jaw Titans, born from Falco’s subconscious longing for liberation and recurring visions of birds soaring above war zones. Interactions with Reiner Braun and Eren Yeager expose Falco to the entrenched cycle of vengeance between Marley and Paradis. Though initially deceived by Eren, he discerns the common humanity binding both sides. His tactical ingenuity surfaces in high-stakes scenarios, from devising protective lies for Gabi to allying with former foes. When the Rumbling begins, Falco’s Titan form becomes essential, ferrying allies to halt Eren’s devastation. His flight ability, merging inherited Beast Titan traits with personal yearning, epitomizes his role as a mediator between factions. Amid global collapse, he remains steadfast in defending those he loves and pursuing peace, embodying his transformation from conflicted cadet to pivotal peacemaker. Central bonds shape his path: unspoken feelings for Gabi, guidance from Reiner, and strained yet forgiving ties to Paradis soldiers like Connie Springer. His arc echoes themes of sacrifice, war’s devastation, and clinging to humanity under oppression’s weight.
