Connie Springer

Connie can be best described as outgoing and impetuous. He has an easy time expressing his opinions, and enjoys flaunting his skills, especially during his days as a trainee. Despite being in the military, Connie starts off as rather unfocused, and enjoys goofing around and messing with his friends, but can also be a bit dense at times. Later, Connie's naive enthusiasm falls away after multiple close encounters with the Titans. He never becomes more serious, though to his frustration, he still has some difficulty comprehending new developments as they appear. Connie also comes to terms with his own limits, disliking his lack of power, but eager to prove his worth. For a long time, Connie remained optimistic, consistently caring for the well-being of his friends, family and village, and being willing to help in any way he can. However, this soft spot and the tragedies he goes through takes a toll on him. Initially reacting to those situations with denial, alarm and search for negotiation with those he was betrayed by, he becomes with each new grief more prompt to anger, irritation and hatred, losing his optimism and gaining in readiness to act against his opponents in order to protect the few selected friends he considers to be family. His mother's transformation into a Titan appears to have had a big effect on his psyche, and combined with all of the tragedies he went through caused him to take drastic measures to ensure she became human again: this was primarily seen when Connie suggested feeding Falco to his mother. He left his friends and took Falco hostage to his village, lying to him about taking him to a hospital and abusing his trust. This reached the breaking point when Connie tricked Falco into brushing her mother's teeth, with the intention of pushing him into his mother's mouth, and when Armin and Gabi arrived to stop him, he held a blade to Falco's neck. However, when Armin chose to jump into Mrs. Springer's mouth and allow himself to be eaten, Connie saved him at the last second, coming to the realization that his mother wanted him to be a good soldier, and knowing that having eaten Armin would just make her sad.

Human form
Connie used to be one of the shorter members of the Survey Corps, standing two centimeters shorter than Levi Ackerman. He has a slim build, with gray eyes, and his brown hair is distinctively kept shaved. Connie is typically dressed in standard military garb, and will don the Survey Corps cape when on missions. His casual attire consists of a simple long-sleeve white shirt and shin-length brown slacks. By the year 854, Connie has grown significantly taller, now standing slightly above average height. His hair has grown slightly longer, but stays in the same general style, and his facial features have sharpened. During the Raid on Liberio, he wears a black uniform, with belts and support rods for his anti-personnel vertical maneuvering equipment.

Connie's abilities put him in the top 10 of the graduated trainees. He is said to be "slow on the uptake but makes very sharp turns." Connie's combat skills were shown to be quite advanced as he is able to take out and outmaneuver several Yeagerists. He is seen killing a Titan that is attacking Annie's Female Titan. Connie is noted as being one of the quickest soldiers using vertical maneuvering equipment. He is so fast that he rarely ever has to engage Titans in combat.
