Kuklo

Kyklo is the main protagonist of the Shingeki no Kyojin prequel Before the Fall. He is the son of Heath and Elena Munsell and miraculously survived when his heavily pregnant mother was swallowed whole by a Titan.

History
After the death of her husband, a Squad Leader in the Survey Corps during an expedition, Elena Munsell became a member of a Cult that worshiped Titans. While heavily pregnant, she led a mob responsible for opening the gates and was devoured by the Titan that entered. Her corpse was discovered in a ball of Titan vomit, and two members of the Survey Corps cut her open after witnessing movement. Inside, they discovered her infant son had miraculously survived.

Dubbed the "Child of Titan", he was hated and feared by the people within the Walls. He was raised in captivity, and kept alongside many exotic animals. He parts himself from his past and gambles on the fate of humanity by enlisting in the Survey Corps. Kyklo has survived from the outside wall: in order to defeat the Titans, he gets his hands on the 3D manuever gear. Although the gear is still imperfect and causes a troublesome incident for Kyklo, he fights the Titans. Whether it is because it is his fate to fight them, or it is because of his past, he fights against them.

Trivia

 * His name, Kyklo (キュクロ), was taken from German word for Cyclops, which is Kyklop/Zyklop (キュクロープ). He was named so because he only has one functioning eye (his left eye).
