Art style: Anime / Manga.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Rick Sanchez, an elderly, lanky scientist in his seventies, tall and gaunt with a slightly hunched posture. Pale bluish skin, a long angular face with a large protruding chin, thin frowning mouth, heavy eyelids and dark unibrow. Wild, spiky light-blue hair standing up in erratic tufts, faint stubble drool-flecks at the corners of his lips. He wears a knee-length pale-blue open lab coat over a plain teal t-shirt, brown trousers and simple grey sneakers. In one bony hand he grips his metallic portal gun, its emerald-green muzzle faintly glowing. His expression is cynical and sardonic, yet a rare flicker of genuine unease tightens his eyes. Behind him a fractured, glitching interdimensional void of collapsing green portals and broken code fragments.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Anime / Manga" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Anime / Manga". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Anime / Manga" idiom, not in any other medium.
