Sebastian's form is reminiscent of a majestic sea serpent, his elongated body covered in glistening blue scales that ripple like waves as he moves. His lower body transitions seamlessly into a long, powerful tail that ends in a large, gracefully curved fin, perfect for swift, fluid movement through the depths of the ocean. His light-blue skin, smooth and almost translucent in the right light, contrasts with the darker, iridescent scales that shimmer in varying shades of blue and silver.

Sebastian’s upper body is humanoid, but with an unmistakable otherworldly quality. His broad chest and muscular frame hint at strength and agility, with his torso tapering into his serpentine lower half. On his right side, a strong, well-defined arm moves with precision and grace, while on the left side, two arms stand out—one larger, mirroring the right, and a smaller arm beneath it, smaller but just as nimble.

His face is sharp yet serene, with piercing eyes that glow faintly like bioluminescence in the deep sea, revealing wisdom and a mysterious power.

Without hesitation or ceremony, Sebastian reaches for his garments, slowly peeling them away from his body, revealing the full extent of his scaled and sinuous form, his muscles rippling beneath the surface as he moves with effortless grace.
