Moses Braun (モーゼス・ブラウン Mōzesu Buraun?) was a member of the Survey Corps and the first person shown to be killed by a Titan at the beginning of the series. He appeared to show great passion for humanity and was a conditioned soldier.
Braun had unkempt, cheek length, blond hair and light-green eyes. He was well built and wore the typical uniform of a member of the Survey Corps along with the common green cloak.
During a mission with the Survey Corps, Braun's squad begins to take formation around a Titan via horses in order to kill it, and soon after, he switches to vertical maneuvering equipment with his team mates. He then takes position and attempts to kill the targeted Titan, but is killed, and the Survey Corps is only able to bring back his arm.
When the Survey Corps returned to the Shiganshina District after their failed expedition, his mother starts asking for him, and the Commander of the Survey Corps, Keith Shadis, gives her his arm which was all that remained of him. She cries and pleads with Keith, asking if his death contributed to humankind's retaliation. He denies and cries that they again did not make any progress on the recent expedition.
- The relation between Moses' family and the Braun family from which Reiner Braun hails, if any relation exists, is unknown.
- Moses is a biblical prophet, famous for his participation in the Exodus and the creation of the Torah. In the story of the Twelve Spies, he sends one man from each of the twelve tribes of Israel to explore Canaan, and at their return they describe the land as being inhabited by giants and surrounded by large Walls.
- In German, his surname "Braun" means "brown".
