Luke Cis (Anime)

Luke Cis (ルーク・シス) was a skilled member of the Scout Regiment and a participant during the 57th Expedition Outside the Walls.

Appearance
Luke had chin-length, straight brown hair tied back in a ponytail and hazel eyes. He wore the typical Scout Regiment uniform.

The Female Titan arc
Luke is seen giving out uniforms to the new recruits with Dita Ness shortly after they arrive at the Scout Regiment HQ.

He is seen on the 57th expedition mounted from the Calaneth District into the Titan-infested lands outside Wall Rose. Not long into the expedition, Luke works with Ness to take down an abnormal Titan, despite being in an open field where their vertical maneuvering equipment can not be used at full effect; Ness takes out the Titan's ankles, and Siss destroys the nape of its neck as it falls. However, almost immediately after, the mysterious Female Titan appears. Following Ness' lead again, Luke tries to strike at the Titan, but it intercepts and crushes him effortlessly, before moving on to kill Ness moments later.
