黑暗奇幻組合機甲陣容

A dramatic dark fantasy mecha lineup on a black smoky studio-like background, rendered as ultra-detailed concept art with a wide cinematic composition. Show exactly 6 sinister biomechanical figures standing side by side on a glossy reflective floor, all designed as parts or forms of a combining robot set. The overall design language is gothic, infernal, and baroque: blackened steel, tarnished silver armor, serrated edges, thorn-like protrusions, skeletal filigree, red glowing cores and eyes, with subtle white-metal highlights and traces of crimson energy. The mood is ominous, majestic, and apocalyptic.

From left to right: first, a towering humanoid overlord mech, the largest figure in the lineup, with a crown-like halo ring behind the head, huge layered black feathered or blade-like wings draping downward, ornate chest armor with a bright central core, multiple red glowing orbs embedded asymmetrically, and a long staff or spear held diagonally. Second, a tall slender angelic-demonic humanoid mech with an elongated body, spiked antler-like crest, narrow waist, blade-like hanging armor panels, and red glowing shoulder nodes, posed upright and regal. Third, a beast unit on four legs, low and aggressive like a demonic wolf or draconic hound, covered in curved blade armor and long swept-back horns, with glowing red eyes and an arched tail or spine silhouette. Fourth, a heavy quadruped siege unit, bulkier and more armored, with a forward head assembly and two large circular shield-like wheel structures mounted on its sides, full of radial spikes and a glowing red core at the center of one wheel. Fifth, a centaur-like or upright beast warrior mech with long legs, layered armor, horned head, and a sharp avian-draconic profile, slimmer than the heavy unit but still imposing, with red lights in the chest and head. Sixth, a symmetrical winged emblem-like unit resembling a mechanical phoenix crest rather than a humanoid body, with two broad metallic wings spread outward around a central halo ring and a tapered hanging tail piece set with 3 visible red gem-like cores.

Keep the palette nearly monochrome except for the glowing reds. Emphasize razor-sharp silhouettes, intricate engravings, layered armor plates, cables and skeletal mechanical details, smoke drifting behind the figures, and faint reflections beneath their feet. The image should feel like a premium concept sheet for a {argument name="theme" default="dark combining robot"} in the style of hyper-detailed dark fantasy sci-fi illustration. Use a panoramic aspect ratio, front-facing lineup presentation, and high contrast lighting that picks out metallic edges against the deep black background.
