Cosmic horror anime entity, amorphous mass of eyes and tentacles, reality-warping presence, emerging from dimensional tear, mind-bending geometries, sanity-breaking visions, incomprehensible symbols, eldritch awakening, reality-fracturing aura, non-euclidean movement patterns, perception-altering gaze effects, maddening void atmosphere, impossible objects, Hilbert curves.

Retro sci-fi pulp style, cosmic horror, a monstrous robotic entity emerges from an interdimensional portal, surrounded by the remnants of fallen civilizations and otherworldly phenomena, tentacle-like cables, reality-warping effects, eldritch symbols, a chaotic scene with a swirling energy vortex, a cosmic void with floating debris, a vibrant alien sun backlighting, eerie color shifts, and a bold contrasting color palette.
