Mike Zacharias (ミケ・ザカリアス) is a member of the Survey Corps under Erwin's command.

Attack on Titan: No Regrets
In the year 844, prior to the fall of Wall Maria, Mike served as a member of the Survey Corps under Erwin Smith's command when the latter was still a Squad Leader. As one of Erwin's most trusted comrades, Mike took part to the capture and the recruitment into the Survey Corps of Levi and his friends. During the mission, he teams up with Erwin to get Levi and is the first to attack him but is quickly defeated. Erwin eventually comes to attack their target. When he is disarmed, Mike intervenes, stopping Levi's gesture and telling him to look at his friends, who were captured by Erwin's squad members. After that, Erwin interrogates the trio, and, seeing none of them was willing to cooperate, Mike begins the physical threats by hitting Levi's head against the ground.

After the rain during the second part of the expedition outside the Walls ceased, Mike and Erwin manage to find Flagon's squad, only to learn a group of Titans killed most of the group before being slaughtered by Levi. When the latter attacks Erwin, Mike goes to help him but is ordered by Levi not to intervene. As the two discuss about Lovof's document, Mike worries about Erwin bluntly explaining all his plan to Levi. Eventually, Levi calms down and the three men leave to join the rest of their comrades.
