Gien wears a full set of black body armor with yellow highlights that covers his entire body, and also a purple cape which is secured around the front of his chest and drapes down his back. His helmet protects his whole face, except for his eyes. It features spiral horns, one on each side of the helmet, resembling those of a mountain goat.
Golden Age Arc Edit
As the commander of the Black Sheep Iron Spear Knights, Gien leads his army into battle against battalions from the army of Midland. After his army starts to gain the advantage, Guts enters the battle assisting the latter side. Upon bursting into the battle, Guts begins to decimate Gien's soldiers with ease. The commander engages Guts in fight, but meets his demise after only one strike. His army is then wiped out thoroughly by the Band of the Falcon and Midland's reinforcements who join the fray soon after.
- Gien and the entire battle he participates in are exclusive to the movie Golden Age Arc I: Egg of the Supreme Ruler, the first in a trilogy of films adapting the Golden Age Arc of the manga.
