One complete massive stationary orbital rail cannon boss,...

One complete massive stationary orbital rail cannon boss, native 128x128 pixel sprite on transparent background. Same old crater emplacement identity as first reference: deep-navy square armored base, silver-white broad horizontal rail barrel, a seed-gold energy chamber inset low in its body. Strict orthogonal SIDE ELEVATION facing screen RIGHT at 90 degrees; cannon barrel and muzzle extend horizontally right, no front view, no isometric or three-quarter angle, never show two broad faces. Thick naval-blue pedestal rests on broad two-layer rectangular ground base; NO tracks, wheels, human crew, extra gun barrels or wings. One enormous silver rail barrel with two clear rectangular coil housings and a dark round muzzle end at far right. Under the barrel, one readable amber-gold circular energy chamber framed by navy shielding plates. Two short silver stabilizer feet share a horizontal ground baseline. Wide horizontal silhouette occupying about 116 by 88 native pixels, full structure visible with margins. Broad geometric pixel blocks, strong dark contour, two tones per surface, sparse clear seams. Deep navy, silver white, dark purple shade, small gold energy core. No rust texture, no tiny panel lines, no gradients, no glowing haze, no terrain or shadow. The small first image establishes cannon identity; the battle tank reference supplies native pixel craft only, do not copy its mobile chassis.
