Abel (アーベル Āberu?) is an officer (上官 Jōkan?) in the Scout Regiment Fourth Section under the command of Hange Zoë, who is noted for his trademark glasses, or "goggles." He participated in the 57th Exterior Scouting Mission and often accompanies higher-ups, such as Hange and Levi, on serious missions.
Abel is a man of average height, with light skin, short, blond hair, and light stubble on his chin and cheekbones. He is noted for always wearing thick-rimmed glasses with bands around his head, to prevent them from falling off in combat. His clothing consists of the typical uniform of the Scout Regiment with the green cloak worn on expeditions.
Abel is a serious man and a devoted Scout Regiment member, always acting bravely in battle and following his duties as a soldier.
StoryFemale Titan attracts several Titans with a loud screech, and Erwin Smith orders the supplies guard unit to intercept the Titans, with Abel and several other soldiers trying to distract them. However, they are ignored by the wave of Titans as they go to eat the Female Titan. Abel is exhausted after the attempt to kill the Titans surrounding the Female and retreats after Erwin gives the order.
Abel watches as Hange, aided by Moblit and other soldiers, make a second attempt to capture the Female Titan. They manage to succeed, but Hange brags about what she plans to do with her, causing Annie to kick the special target restraining weapon and escape once more.
Abel helps cover the Titan inside of Wall Sina, after Eren and Annie's battle exposes it. He then watches with the rest of his squad as Hange Zoë threatens Nick for answers.
They stop in Ehrmich District where Hange goes over a report about Annie Leonhart's background with a number of Scouts, including Abel. He hears Armin, Eren, and other members of the 104th discuss whether it is possible that Reiner Braun and Bertholdt Hoover could have been working with Annie.
Hange then takes a group of splinter group soldiers to Utgard Castle to rescue Historia Reiss while the main body continues on with Erwin. Abel is with Hange's team and participates in the battle against the Titans when they arrive at Utgard.
Afterward, Abel returns with the rest of the Scouts to Wall Rose to recover. When Hannes' Garrison squad arrives to report that there is no breach in the Wall, he is among the soldiers who gather around to listen. Learning that there is no breach, Hange calls for the Scouts to fall back to Trost and Abel prepares to go with them, but they are stopped by the sudden appearance of the Colossal and Armored Titans.
Abel and the other Scouts jump off the Wall to avoid the Colossal Titan's attack and Hange orders her soldiers to swarm it. They use their omni-directional mobility gear to swing around the Colossal Titan and as they dodge around its fist, Abel notes that though the Titan is big, that is all that it has going for it. However, before they can reach its nape, the Colossal Titan emits a scalding burst of steam that drives all of them back.
Hange leaves three of the four squads with her to watch Bertholdt and takes the remaining squad, including Abel, to face the Armored Titan, which is fighting Eren in his Titan form. During the battle, Mikasa and Armin land on the ground away from the Wall in an attempt to get Eren to escape and avoid being kidnapped. Abel comes down to call the two of them back, saying that it is dangerous. They follow him back to the Wall, and so does Eren.
Reiner charges after him, and when they next engage, Eren gains the upper hand. The Armored Titan roars in desperation and Abel quickly searches the area for Titans in preparation for a similar event to the one that cost them the capture of the Female Titan. He reports to Hange that there are no other Titans sighted in the area.
However, the Colossal Titan reacts to the roar and plunges down from the top of the Wall to land on Reiner and Eren. The resulting explosion knocks back and heavily injuries almost all of the Scouts around the Armored Titan, including Abel.
Despite never being seen in actual combat, it is implied that Abel is a fairly capable fighter, as he survived the 57th Exterior Scouting Mission, during which he directly engaged the Titan horde that was attempting to devour the Female Titan, and a fight against the Female Titan during the capture operation in the Stohess District. Furthermore, in the 57th Exterior Scouting Mission, Abel was part of the cart guard team, entrusted with the safekeeping of the special target restraining weapon meant to capture the Female Titan. This implies that he is among the few Scout Regiment members who knew about the true objective of the expedition, meaning that he has managed to stay alive for at least the past five years and that he is a trusted member of the Scouts.
- While he is not specifically named in the manga nor the anime, he is credited as "Abel" in the credits of the compilation film Attack on Titan: Roar of Awakening. His nickname "Goggles" has appeared in several forms of media such as the Height Comparison Chart released in the Wings of Freedom DVD/BD Bonus Pamphlet and the Attack on Titan Character Encyclopedia.
- Although Abel is portrayed with brown hair in the first season of the Attack on Titan anime, his hair color is changed to blond in the second anime recap movie to better fit his manga appearance. This change is retained in the second season of the anime.
