Demon Core Portal Device In Sci-fi Lab

Photorealistic image of a futuristic spherical device labeled "DEMON CORE" on a metal lab table, connected by black cables. The sphere glows with vibrant blue and purple neon lights, and its central circular window reveals a swirling green and yellow portal containing small, crab-like alien creatures. In the background, a large portal or screen displays a cavernous, glowing green alien landscape with more creatures, one of which appears to be a grey, cat-like alien with glowing eyes, stepping out. The setting is a dimly lit, high-tech science laboratory with glass walls, showing other lab equipment and computer monitors displaying data. The overall mood is mysterious and tense, with cool blue and green tones dominating the lighting, creating strong reflections on surfaces.
