Tseng
Leader of Shinra's Turks in Final Fantasy VII. Apparently killed by Sephiroth in the Temple of the Ancients, but turns up in Advent Children when he is captured by Kadaj, Yazoo, and Loz along with fellow Turk Elena, and later after being rescued by Vincent Valentine. He also appears in Last Order and Before Crisis, both parts of the Compilation of Final Fantasy VII. Tseng has known Aerith since she was a child and some people think he has feelings for her.
Tseng probably gets annoyed with Reno a lot.
