An epic, highly detailed anime-battle manga style digital illustration of the fully transformed Rago. The dynamic wide composition centers on Rago, a massive, terrifying shadow entity with bio-mechanical dark teal and jade-green armor plates with organic, thorny protrusions and glowing golden runic symbols. His colossal form is completely covered by thousands of ferocious, glowing emerald-green eyes following the musculature and armor contours. His face features a multi-eyed structure and a cavernous, open mouth with a vicious, multi-row, sharp-toothed grin. Directly integrated above and behind his head is the gigantic, cosmic 'Black Star'—a colossal, swirling, deep teal and dark cyan galaxy vortex with star fields and cosmic nebulae. Rago stands in a powerful, symmetrical front-facing pose, with a central, massive clawed hand reaching forward toward the viewer. A ferocious, chaotic energy aura of intense electric yellow and lime-green lightning crackles around his body, limbs, and eyes, creating jagged, high-energy patterns. The perspective looks up at the entity, with cracked, desolate barren earth at the bottom. High-contrast, dynamic lighting with bold line art, sharp highlights, and rich saturated colors against the complex entity. No text or dialogue panels.
