Keith Shadis

Before Erwin took over, Shadis was Commander of the Survey Corps. Hundreds of soldiers died under his leadership without anything being achieved; he resigned and became an instructor.

As an instructor he is harsh and theatrical, but his judgement is sound: he sees precisely where each recruit belongs. His verdict on himself is merciless — he has simply turned out to be an ordinary man.

In season 4 he finally gets the moment in which he can give his life for something that works. He does not hesitate for a second.

• Shadis knew Grisha and Carla personally; his conversations with Grisha are one of the few outsider’s views of the Yeager family.
