Goggles is the unofficial name of a member of the Survey Corps Hange Zoë's squad, noted for his trademark glasses, or "goggles". He participated in the 57th Expedition beyond the Walls and often accompanied higher ups on serious missions, such as Hange and Levi Ackerman.

Appearance
Goggles was a tall man with light skin, short dark brown hair, light stubble on his chin and cheek bones. He was noted for always wearing thick rimmed glasses with bands around his head, apparently to prevent them from falling off in combat. His clothing consisted of the common uniform of the Survey Corps.

Personality
Goggles was a serious man and devoted Survey Corps member, always acting bravely in battle and following his duties as a soldier. He seemed to be a loyal and reliable subordinate, since he was trusted to accompany high rank members in critical situations, like the meeting in the hideout where Eren and Historia were being hidden from the government and the following operation to rescue them from the Military Police First Interior Squad.

The Female Titan arc
The Female Titan attracts several Titans with a loud screech and Erwin Smith orders the supplies guard unit to intercept the Titans, with Goggles 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. He is exhausted after the attempt to kill the Titans surrounding the Female and retreats after Erwin gives the order.

Goggles watches as Hange Zoë, aided by Moblit Berner 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, making Annie to kick the Special Target Capture Weapon and escape once more.

Clash of the Titans arc
Goggles is later seen in the ruins of Castle Utgard forming part of the group responsible for rescuing Ymir, Reiner Braun, Bertolt Hoover, Connie Springer, and Krista Lenz. He is later seen with other Survey Corps soldiers trying to attack the half transformed Colossal Titan, but is forced back when it releases large amounts of hot steam. The soldiers then withdraw and waited for it to stop releasing steam under Hange's orders.

The Uprising arc
Goggles is seen again when Eren Yeager is rescued, looking at Mikasa's wounds and recommending that she get to a doctor quickly.

Goggles is reunited with Squad Levi, Hange, Keiji and Nifa, listening as they discuss Armin's plan to seal the hole in Wall Maria using Eren's Titan hardening abilities, and as Hange reveals Pastor Nick's murder at the hands of the Military Police First Interior Squad.

Soon after, Goggles can be seen with Squad Levi while they speak with Dimo Reeves and Flegel Reeves, listening to the message from Erwin brought by Nifa. He watches as Levi interrogates Historia and forces her to accept her role as queen. He also hears Nifa speak about Erwin's plan to have Eren and Historia handed from the Reeves Company to the Military Police and track them to the location of Historia's father, Rod Reiss, the true ruler of the Walls.

Later on, while a group of members of the Military Police carry two caskets from a funeral home to a carriage, presumably hiding the kidnapped Eren and Historia, Goggles and Keiji monitor the scene from a concealed location, with Nifa and Levi monitoring from a roof. Shortly after, Kenny Ackerman and his subordinates make their appearance and several of them ambush the soldiers, killing Goggles and the rest of them, except for Levi. The bodies of Goggles and Keiji fall to the ground from the rooftop, much to Levi's horror.
