An epic, highly detailed illustration of a red Tyrannosaurus-like robot in battle armor. The mech features thick armor plating, exposed hydraulic pistons, cables, and sharp metallic claws. The T-Rex has an open jaw with jagged teeth, glowing cockpit-like eyes, and a bulky tail to emphasize power. The color palette is bold reds, oranges, and metallic tones with orange highlights. The creature is in a dynamic forward-leaning attack pose with one claw extended, set against a vibrant explosive background with radiating streaks of teal, lime, orange, and beige. The artwork is rendered in a thick comic-book style with heavy black outlines, high-contrast shading, and painterly brush strokes. The scene resembles a retro-futuristic mecha toy or transformer aesthetic. Include the stylized caption 'transformus rex' at the bottom in a bold italic font.
