Conny Springer is a graduate of the 104th Cadet Corps, ranking 8th in his class, and later became a member of the Scout Regiment. Initially lighthearted and carefree, Conny grew through painful experiences into a soldier determined to protect his friends and honor his family. 

Conny was one of the shorter members of the Scouts, standing slightly below Levi’s height during his cadet years. He had a slim build, bright hazel eyes, and distinctive gray hair kept shaved close to his scalp. His casual attire included a simple white shirt and brown slacks, while on duty he wore the standard Scout Regiment uniform with cloak.

By the year 854, Conny had grown taller and more mature in appearance, his hair slightly longer and facial features sharper. During the Raid on Liberio, he wore a black anti-personnel uniform equipped with omni-directional mobility gear. 

When transformed into a Pure Titan, Conny’s Titan was large enough to reach the Armored Titan’s head. Its features included exposed gums and teeth, a lack of an upper lip, and missing flesh on the cheekbones, though it otherwise retained recognizable human traits. 

Conny began as outgoing, impetuous, and playful, often joking with friends and sometimes acting recklessly. Despite his lack of focus as a cadet, he was deeply loyal to his comrades.

As the war progressed, Conny’s optimism faded under the weight of repeated tragedies. He grew more serious, angry, and frustrated by his perceived weaknesses, but remained eager to prove his worth and protect those close to him. His mother’s transformation into a Titan deeply scarred him, leading him to take desperate measures — including nearly sacrificing Falco to restore her humanity. However, Conny ultimately rejected that path, realizing his mother would want him to live honorably and fight as a soldier, not betray his humanity.
