Kuklo

Kyklo is the main protagonist of the Shingeki no Kyojin prequel Before the Fall. He is the son of Heath and Elena Munsell. Kyklo was born from Elena's corpse that was vomited out by a Titan.

History
Kyklo was found as a baby crying in a mass of Titan vomit, amidst the dead titan flames. He is called "child of titan" and is essentially hated by the people inside the walls. He also seems to grow unnaturally fast. He parts himself from his past and gambles on the fate of humanity by enlisting in the scouting legion. 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).
