Iron Visor

From a distance it looks like a soldier's helmet drifting alone in space. Up close, it is a wall. Layers of olive and moss green plating stack over each other like scales, and a single red eye burns behind a grated faceplate. A long barrel juts from under the jaw and throws a twisting ribbon of white and pink fire. Iron Visor was once a border sergeant named Ottar Venn, who spent thirty years guarding a gate nobody else wanted. When The Capital asked for a soul to hold the new frontier line, he raised his hand first. Now he is the gate. His defense is the thickest in his squadron, and his plates shift on their own to catch incoming fire. His signature move is the Visor Lock: he closes his faceplate, takes every hit meant for the ships behind him, then opens up and fires one Overcharge Ribbon, a special attack that unspools across the battlefield like a burning flag. He moves slowly. He never needs to move fast. Nothing gets past him.
