Goggles is an unofficial name of a member of the Survey Corps who participated in the 57th Expedition and often accompanied higher ups on serious missions, such as Levi Ackerman and Hange Zoë.

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

Personality
Goggles was quiet and very loyal to his superiors, earning their trust. He showed a calm and serious attitude but was able to act properly as a soldier during times of crisis, such as when he directed Marlo Freudenberg and Hitch Dreyse to their superiors after the battle with Annie Leonhart.

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, aided by Moblit Berner and other soldiers, make a second attempt to capture The Female Titan. They manage to succeed, causing Hange to brag about what she plans to do with Annie. After hearing this, Annie kicks the Special Target Capture Weapon and dislodges the hooks; allowing her to escape yet again.

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 Bertolt, The Colossal Titan, while half transformed 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 Zoë'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. Soon after, Goggles can be seen with Squad Levi while they speak with Dimo Reeves and Flegel Reeves, listening to the message from Erwin as brought by Nifa. He watches as Levi interrogates Historia Reiss and forces her to accept the 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 Brigade. Nifa states that Erwin wants them to track Eren and Historia through The Reeves Company to their end location. Which he believes will be 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. 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.
