AOT Name Generator

Attack on Titan takes place in a world modeled on early twentieth-century Germany, and Hajime Isayama named almost everyone accordingly. Eren, Armin, Reiner, Bertholdt, Annie, Erwin, Petra, Gunther, and Hange are all German or Germanic given names, and the surnames follow: Yeager (from Jager, hunter), Braun, Hoover, Leonhart, Kirstein, Springer, Braus, Reiss, and Fritz. The one deliberate outsider is Mikasa, whose Japanese name marks her as the last descendant of Hizuru, and the Azumabito clan keeps that thread going in later arcs. Marleyans use the same Germanic pool (Theo Magath, Willy Tybur), while volunteers like Onyankopon and Yelena signal a much larger world.

A convincing original character therefore needs a plausible German first name and a surname that sounds like it belongs on a Berlin doorbell circa 1910: Falk Rieger, Liesel Kohl, Wolfram Diehl. Nobles from inside Wall Sina lean older and grander (Reiss, Fritz, Tybur); Survey Corps recruits and Marleyan Warriors are ordinary working names; Hizuru characters take Japanese names.

The list above pairs the canon cast with a large set of original names built on those rules, split into male, female, Hizuru, and overseas volunteers, so you can place an OC in any faction without breaking the setting.
