Eren Yeager Eren Jeager (Japanese: エレン・イェーガー, Hepburn: Eren Yēgā), spelled Eren Jaeger in the Funimation dub, is a fictional character and the protagonist of the Attack on Titan manga series created by Hajime Isayama. Eren is a teenager who swears revenge on enormous creatures known as Titans that devoured his mother and destroyed his town. In order to defeat the Titans, Eren, alongside his childhood friends Mikasa Ackerman and Armin Arlert, enlist in the Military and join the Survey Corps—an elite group of soldiers who fight Titans outside the walls. As the story progresses, later learning it was his father's doing, Eren gained the power of becoming a Titan later identified as the titular Attack Titan (進撃の巨人, Shingeki no Kyojin). Eren uses this power to give his people an advantage to defeat their enemies while learning of their true identity and their own history.
Titan (moon) Titan is primarily composed of water ice and rocky material. Much as with Venus before the Space Age, the dense opaque atmosphere prevented understanding of Titan's surface until new information from the Cassini–Huygens mission in 2004, including the discovery of liquid hydrocarbon lakes in Titan's polar regions. The geologically young surface is generally smooth, with few impact craters, although mountains and several possible cryovolcanoes have been found.
