Three Mecha Combination Lineup

Create a high-detail vertical sci-fi concept art scene showing a “combination sequence” lineup of three futuristic transformable combat mecha vehicles inside a vast white-and-silver orbital hangar. Use a centered, perfectly symmetrical top-down / high three-quarter perspective looking down a long runway, with the three units aligned in a straight vertical column from top to bottom, as if waiting to combine into one giant robot. The hangar floor is glossy pale metal with panel seams, blue illuminated guide strips, recessed tracks, and tall mechanical support pylons along both left and right sides. Add electric blue energy arcs, glowing thruster halos, and holographic aura effects around each unit. Subject details: include exactly 3 discrete mecha units, each with a visible floor label directly beneath or near it: 1) top unit labeled “UNIT 03 SHADOW”, a sleek white, black, and blue winged stealth fighter-drone mecha with eight sharp radiating wing/fin assemblies and a pointed nose; 2) middle unit labeled “UNIT 02 BULLDOG”, a heavy black, gray, and white tank-like armored mecha with caterpillar treads, bulky rectangular shoulder weapons, large articulated mechanical arms raised outward, and a central cannon barrel; 3) bottom unit labeled “UNIT 01 RAIJIN”, the largest red, white, black, and gunmetal jet-mecha with twin cylindrical engine pods, angular red wing armor, a long dark cockpit nose, and blue thruster glow. Make the bottom unit dominate the foreground, the middle unit occupy the center, and the top unit appear smaller in the distance. Text content: render the three labels clearly in a compact futuristic HUD font on the floor: “UNIT 03 SHADOW” in blue, “UNIT 02 BULLDOG” in orange, and “UNIT 01 RAIJIN” in red and white. Optional customization: the unit names may be UNIT 03 SHADOW, UNIT 02 BULLDOG, UNIT 01 RAIJIN. Visual style: ultra-detailed hard-surface mecha design, cinematic Japanese robot-anime inspiration, photorealistic CGI rendering, crisp panel lines, micro decals, metallic bevels, exposed pistons, weapon mounts, glowing blue LEDs, volumetric light, clean futuristic industrial environment, high contrast but bright white hangar lighting. Use a vertical 4:5 composition, symmetrical layout, sharp focus throughout, no people, no smoke obscuring the units, no extra robots beyond the three listed units.
