A brooding, spectral knight stands poised for battle, cloaked in shadow and adorned with sharp, curved armor plates that gleam with an ethereal blue and cyan luminescence. The figure wields a double-bladed sword that emits an otherworldly, supernatural glow, hinting at dark power. The overall mood is one of gothic menace and agile, deadly intent, reminiscent of characters from Bloodborne, Soul Reaver, and Metroid. This collection of sprites, rendered in a 128x128 resolution, showcases the knight in various stances, from imposing forward-facing poses to more dynamic, action-oriented depictions, all presented with transparent backgrounds for seamless integration into a 2D game environment.
