Connie Springer hails from Ragako village within Wall Rose. Aspiring to bring honor to his family and village, he joins the 104th Cadet Corps aiming for the Military Police Brigade. Standing 158 cm tall with a slim build, shaved gray hair, and hazel eyes, he ranks among the shorter cadets. Despite academic difficulties, his physical agility, balance, and mastery of omni-directional mobility gear earn him 8th place at graduation. He exhibits an outgoing, impetuous personality during training, frequently joking with peers like Sasha Blouse. Struggling with comprehension, he displays moments of denseness, such as incorrectly saluting on the first day. Witnessing Eren Jaeger's resolve during a clash with Jean Kirschtein motivates Connie to train more seriously, though he retains his lighthearted nature. He later chooses the Scout Regiment after Eren's impassioned speech about fighting Titans, despite denying its influence. In the Battle of Trost District, Connie engages in crucial operations defending against Titan incursions. He aids Mikasa Ackerman when her gear fails and supports Armin Arlert's plan to infiltrate headquarters for gas resupply. During this mission, he observes Eren's mysterious transformation into a Titan aiding humans, later reporting these events to comrades. A turning point arrives when Titans appear inside Wall Rose. Returning to Ragako, Connie finds his village deserted and ruined. Inside his family home, an immobilized Titan bearing his mother's resemblance whispers "welcome home." Hange Zoë confirms the Beast Titan transformed his entire village into Pure Titans. His mother's Titan form, lacking flesh on cheekbones and upper lip to expose teeth and gums, retains human-like features. This tragedy fuels Connie's anger and thirst for vengeance. Subsequent events reshape him. His mother's state and accumulating losses, including Sasha Blouse's death, erode his optimism. He grows prone to anger and drastic actions, attempting to feed Falco Grice to his Titanized mother to restore her humanity. He deceives Falco and nearly executes the plan, halting only when Armin offers himself. Connie intervenes, realizing his mother would reject such an act and value his integrity as a soldier. By 854, Connie stands taller with a more mature appearance, slightly longer hair, and sharper features. He participates in major conflicts like the Raid on Liberio, equipped with specialized anti-personnel gear. Enduring profound trauma, he survives the global conflicts and eventually joins the Alliance in pursuit of peace.
