━━━━━━━━ COPY FROM HERE ━━━━━━━━

Create an original, epic vertical poster (2:3 portrait): a Japanese "yami-kawaii" monster scene in the spirit of 80s thrash metal record sleeves, cute-creepy and loud, built ENTIRELY as a handmade food collage of real potatoes and potato skins splattered with explosive neon paint. Mix two visual worlds: radioactive nuclear-apocalypse thrash (gas masks, hazard symbols, mutants, ruined cities) and cold biomechanical horror (bone fused with machinery, black-and-bone tones), all rebuilt from potato. No satanic, occult or religious symbols anywhere, including crosses and stars, in the corners or the background.

CHARACTER CHECK (do this first): Decide whether the main character is female or male.
1. If a character image or sheet is attached, judge from it by body build, shoulders, chest, jaw and face. Long hair, a slim frame, a mask, armor or a non-human look do NOT mean female; a broad-shouldered, muscular or flat-chested body is male.
2. If no image is attached, use this choice: [GIRL / BOY]. If no choice is written, pick one at random.
Then use only the matching outfit section below (GIRL or BOY), never both.

IDENTITY LOCK (if an image is attached, this overrides every other section): The main character IS the attached character, standing in the middle ground, instantly recognizable even though they are built from potato. Copy exactly from the image: face or mask (same shape, same colors and same material look), head shape, species, horns or antlers (same size, shape and branches), ears, hair colors and hairstyle, eye color, skin color, armor and its colors, tentacles, mechanical or non-human body parts, body type, hands, claws or talons, and feet. The potato pieces and peels that make the character are dyed in the character's own colors, never left plain potato beige. A porcelain or white mask stays porcelain or white: never turn it into a cartoon, yellow or orange bill, beak or snout. Never turn the character into a plain human, never replace their mask with a human face, and never give their features to the creature. The character's own colors always beat the outfit sections and the color palette; neon only appears as paint splashes around them.

COSTUME RULE: If the attached character wears any armor or a mechanical, non-human or signature costume (plate armor, a corset, a bodysuit, a leotard, a cuirass, biomech limbs), they keep that WHOLE look from head to toe: mask or helmet, torso, corset or bodysuit, arm and leg armor, gauntlets, claws or talons, boots or clawed feet, in their own colors. Never replace any of it with a T-shirt, crop top, jeans, skirt, shorts, socks or sneakers, and show bare skin only where the image shows bare skin. The punk look is only ADDED on top: the open potato-skin battle vest, a french-fry bullet belt, studded belts, spiked wristbands, chains and one prop. If the attached character wears normal everyday clothes and has no armor or bodysuit, they wear the full outfit below but keep their own face, hair, horns, ears and colors. If no image is attached, invent a new character from the matching section.

ANATOMY AND BODY PART COUNT (check before finishing): The main character reads clearly with correct anatomy, a natural pose and believable balance, even though everything is potato collage. With an image attached, copy its anatomy and the exact number of every part: hands, fingers or claws per hand, arms, legs, feet, toes or talons, tentacles, eyes, ears, tails, horns or antlers, wings. Without an image, use a normal body about 6 to 7 heads tall: two arms, two hands with five fingers, two legs, two eyes, two ears. Nothing is duplicated, merged, missing or floating, and a hand holding a prop still has the right number of fingers.

ART STYLE (very important): Everything (character, creature, background, sky and frame) is made of two materials arranged together like a giant handmade food sculpture-collage.
1. Real potatoes and potato skins: carved and sliced raw potato, thin curled peels, crispy fried skins, wedges, french fries, ridged chips, hash-brown shreds and piped mashed potato, with visible knife cuts, potato eyes and little green-white sprouts, starchy shine and brown earthy skin texture. Pieces are dyed with food coloring where the design needs color, and cut so their shapes form every surface: skin, armor, hair, vest, teeth, bones, buildings and clouds.
2. Explosive neon paint and food-dye: splashes, splatters, drips, spray mist and brush smears, layered over and between the potato pieces and spilling past the edges.
Show the making: toothpicks, kitchen twine, skewers, crumbs and small shadows between layers. Shapes stay bold with strong silhouettes. It looks like a giant handmade potato punk gig poster, not a plain photo of food, a 3D render or a clean digital painting.

BATTLE VEST (both outfits): a sleeveless battle vest made of stitched potato-skin "denim" with 12 to 20 patches carved from potato slices and chips, ALL DIFFERENT (no repeats) in varied shapes, sizes and dyed colors: made-up band logos in jagged unreadable lettering, radiation trefoils, biohazard signs, mushroom clouds, gas-mask skulls, toxic barrels, lightning bolts, mosh-pit zombies, a melting robot, a mutant rat, a thrashing fist, a cracked cassette, metal pins and a big back patch. No stars or star shapes.

THE GIRL (only if the check says female):
- Look: petite, pale, doll-like, porcelain skin with a faint lilac-grey tint and pink blush; very long two-tone hair made of dyed curled peels and shredded hash browns (for example black and toxic green, or hot magenta and electric cyan) with blunt bangs or twin buns; big glassy eyes with neon highlights and tired dark shadows; a deadpan or quietly mischievous expression, maybe a small fang or an eyepatch.
- Headwear: a carved potato skull-mask helmet, a gas mask pushed up on the head, a spiked crown of fries or a studded bandana.
- Outfit (only for a character with no armor or bodysuit): thrash metal lolita, with the battle vest over a cropped band-style top, a french-fry bullet belt, studded belts, spiked wristbands, chains, a spiked choker, ripped ruffled layers of thin peels, mismatched striped thigh-high socks and chunky white high-tops or platform boots carved from potato.
- Coverage: tasteful, chest and hips fully and opaquely covered.

THE BOY (only if the check says male):
- Look: slim, pale, doll-like young man, porcelain skin with a faint lilac-grey tint; a messy shoulder-length two-tone wolf cut made of dyed peels (for example black and toxic green, or bone white and hot magenta) with choppy bangs over one eye; sharp glassy eyes with neon highlights and heavy dark shadows; a deadpan or smug expression, maybe a small fang, a stitched scar or an eyepatch.
- Headwear: a cracked carved-potato skull-mask or gas mask pushed up on his head, a crooked spiked crown of fries or a studded bandana.
- Outfit (only for a character with no armor or bodysuit): 80s thrash headbanger, with the battle vest over a jacket of dark fried potato skins and a ripped band-style top, a french-fry bullet belt, studded belts, spiked wristbands, chains, a spiked choker, ripped peel jeans or baggy shorts, mismatched striped socks and chunky white high-tops or platform boots carved from potato.
- Coverage: tasteful, chest and hips fully and opaquely covered.

PROP (one only), carved from potato: a pointy V-shaped electric guitar with french-fry tuning pegs, a spiked microphone, a dented skateboard or a boombox.

THE CREATURE (exactly ONE creature with exactly ONE head, and no other big monster anywhere in the image): invent a gigantic kaiju-sized companion, a huge lumpy potato monster covered in peel scales, chip spikes and sprouts, creepy and adorable, clearly loyal to the main character and looking nothing like them, in different colors from the character. It has too many sharp teeth carved from raw potato, mismatched eyes (one big, one small, in different colors), a long pink tongue, and bone, stitching, toothpicks, twine, studs and a few patches matching the character's vest. Its drool is dripping sour cream and neon paint.
COMPOSITION (very important): the creature's single head appears only ONCE, in the FOREGROUND: its huge head and open jaws, or its giant claws, fill the lower third IN FRONT of the main character, cropped by the frame edges. MIDDLE: its neck and body wrap around and behind the character. BACKGROUND: the rest of its body coils up over the setting to the top of the frame, bigger than the buildings, and ENDS IN A TAIL TIP, never a second head. The main character stands in the middle ground, smaller than the creature but clearly the focus, calm and unbothered. Optionally add one tiny sidekick, such as a potato black cat with red eyes or a little mashed-potato ghost.

BACKGROUND (pick one that fits): a nuclear-blasted city of stacked potato blocks and burnt fries under a radioactive sky with a glowing mushroom cloud of piped mashed potato and toxic barrels; a biomechanical factory grown from potato bone and pipes, venting neon smoke; a graffiti back alley full of creepy potato plush toys; or a backstage corridor covered in chip flyers and potato amp stacks. It is all potato and paint too, echoing the vest motifs.
FRAME: a rough border of curled potato peels, with no title, subtitle, caption, signature or readable word anywhere: not in the corners, on clothing, patches, signs or walls. Any lettering stays broken and unreadable.

COLOR PALETTE: explosive neon paint splashes (acid green, hazard yellow, hot magenta, electric cyan, ultraviolet purple) on deep ink black, clashing with the natural potato colors (starchy cream, golden fried yellow, earthy brown peel, crispy dark edges), with bone white and ash grey for the biomechanical parts. Loud, saturated and high-contrast, like a gig flyer under blacklight covered in paint.

VIBE: sweet, dangerous and a little absurd at once, epic and handmade, a deadpan, unbothered character in the middle of the noise.

AVOID: a plain food photo, photorealism of a real person, 3D render, clean digital painting, vector art; the main character turned into a plain human, left plain potato beige, recolored, or with their mask changed into a cartoon, yellow or orange bill; armor, a corset or a bodysuit replaced by a T-shirt, crop top, jeans, skirt, shorts or sneakers; bare skin where the image shows armor; changed eye or hair colors; two creatures, a creature with two or more heads, or the creature only behind the character; the character's face copied onto the creature; extra, missing or fused fingers, limbs, tentacles, tails, horns, antlers, ears or wings; messy anatomy; real brand or band names or logos; satanic, occult or religious symbols (pentagrams, stars, crosses, demons, goat heads, sigils); repeated patches; titles, captions, graffiti words, readable text, watermarks or signatures; sexualized framing or exposed chest or crotch; gore beyond small stylized drips; muddy colors.
