Halloween AI Prompts You Can Copy
A prompt is a short brief. These Halloween prompts name what to preserve, what to change, how to light it and what to avoid, so they work across Gemini, ChatGPT and dedicated image models.
Quick answer
- Copy a prompt, replace the bracketed details with your own, and keep the preservation clause at the top.
- One prompt should change one main thing. Split costume, background and lighting into separate passes.
- For video, reuse the still prompt and add one motion plus one camera move.
- Keep a short negative list: no extra limbs, no text, no watermark, no identity change.
How to use these prompts
Every prompt below has the same skeleton: reference, preserve, change, camera, light, avoid. That order is not cosmetic. The model reads the opening as the job and the ending as the constraints.
Replace the bracketed details with your own. If you are using Gemini or ChatGPT, paste the prompt as a normal message and attach the photo. If you are using a dedicated image model, put the photo in the reference-image field and the prompt in the prompt field.
Five costume prompts
Midnight Braids
Use the uploaded photo as the primary reference. Preserve the subject’s recognizable facial identity, facial proportions, skin tone, approximate age and natural anatomy. Transform the subject into an original gothic Halloween fashion portrait. Change the hairstyle into long violet braids decorated with delicate silver hair accessories. Replace the clothing with an elegant black-and-purple velvet outfit featuring subtle lace and metallic details. Place the subject in a moonlit Victorian garden with soft fog, glowing lanterns and dark autumn foliage. Use photorealistic editorial photography, realistic fabric textures, natural skin details and cinematic soft lighting. Keep the same number of people as the uploaded photo. Avoid altered facial identity, extra limbs, duplicated fingers, distorted anatomy, text, logos and watermarks.
Cosmic Princess
Edit the uploaded photo into an original celestial Halloween princess portrait. Preserve the subject’s recognizable face, natural skin texture, body proportions and pose. Replace the outfit with a midnight-blue fantasy gown featuring silver embroidery, softly glowing star patterns and realistic flowing fabric. Add a delicate silver moon crown and luminous accessories. Place the subject inside a moonlit observatory with a starry sky visible through tall windows. Use elegant fantasy fashion photography, realistic fabric details, cinematic rim lighting, and a deep-blue, silver and violet color palette. Keep the person recognizable. Avoid altered facial identity, extra people, distorted anatomy, text or watermarks.
Haunted Unicorn Mascot
Using the uploaded photo as reference, transform the subject into an original haunted unicorn mascot costume portrait. Preserve the subject’s recognizable face, skin tone, head proportions and original pose. Create a realistic wearable mascot costume with charcoal plush fur, a twisted glowing horn, deep eye sockets with soft green light and a tattered velvet cape. The outfit should look like a believable costume worn by a real person, not a new mechanical creature. Place the subject in a foggy autumn forest at night with carved pumpkins and cold moonlight. Use cinematic costume photography, realistic fur and fabric textures, and a green-violet palette. Do not replace the subject’s face with a mascot head. Avoid extra limbs, distorted hands, duplicated body parts, logos and text.
Forest Witch
Use the uploaded photo as the primary reference. Preserve the subject’s recognizable face, natural skin texture, body proportions and pose. Transform the subject into an original forest witch: layered moss-green and charcoal clothing, a wide-brim hat with dried leaves, small glass bottles and a lantern. Place the subject in a damp ancient forest at dusk with drifting fog and bioluminescent mushrooms. Use cinematic fantasy photography, realistic fabric and botanical textures, and a deep green-amber palette. Keep the person recognizable. Avoid altered facial identity, extra people, distorted anatomy, text or watermarks.
Skeleton Glam
Use the uploaded photo as the primary reference. Preserve the subject’s recognizable face, natural skin texture, body proportions and pose. Transform the subject into an original skeleton-glam Halloween portrait: elegant black evening wear, delicate white bone-inspired makeup around the eyes and hands, silver jewelry, and a deep burgundy backdrop. Keep the makeup clearly decorative and human. Use editorial beauty photography, realistic skin texture, soft rim light and a dark red-green palette. Avoid a full skull mask, altered facial identity, extra limbs, text or watermarks.
Pet costume prompt
Use the uploaded pet photo as the primary reference. Preserve the animal’s original breed, fur color, distinctive markings, eye color, facial appearance and natural anatomy. Dress the pet in a soft pumpkin-inspired Halloween costume with a small green leaf accessory. Keep the costume fitted naturally without covering the animal’s eyes or changing its species. Place the pet in a cozy autumn photography studio with warm lighting and miniature pumpkins. Create a photorealistic professional pet portrait with realistic fur texture and natural shadows. Avoid extra animals, unnatural paws, duplicated limbs, text and watermarks.
Pet prompts fail when the model changes the breed. Put the breed and the markings in the preservation sentence, not in a later style sentence. If the costume covers the eyes, the portrait is unusable; say "does not cover the eyes" explicitly.
Couple costume prompt
Use the two uploaded photos as references for two different people. Preserve each person’s recognizable face, skin tone, body proportions and identity. Do not swap faces and do not add a third person. Dress person one in an original cowboy costume with a hat, vest and boots. Dress person two in an original angel costume with soft feathered wings and a simple halo. Place them back to back in a foggy barn with warm string lights and autumn hay. Use cinematic couple portrait photography, realistic fabric and feather textures, and a warm amber with deep green palette. Keep both people recognizable. Avoid altered facial identity, extra people, distorted anatomy, text or watermarks.
Two-person edits need a model that accepts multiple reference images. Upload one clear photo per person, not a group photo. Say "do not add a third person" and "do not swap faces" explicitly.
Image-to-video prompt
Use the provided image as the exact visual reference and starting composition. Create a continuous five-second cinematic Halloween portrait animation. Keep the subject’s recognizable face, costume, hairstyle and body proportions consistent with the reference. The subject slowly turns their head toward the camera with a subtle mysterious expression. A gentle breeze moves loose hair strands and the edges of the clothing. Soft fog drifts through the scene. The camera performs a slow and smooth push-in. Maintain realistic motion, stable anatomy and consistent lighting. Do not change the person’s identity, replace the costume, add characters or introduce sudden scene cuts. No text or watermarks.
Swap the motion sentence for one of the four recipes on the Halloween video page. Do not stack motions.
A negative list that actually helps
Negative prompts are not magic, but a short list catches the recurring failures:
- altered facial identity, different person, face swap
- extra limbs, extra fingers, duplicated body parts
- text, logos, watermarks, UI elements
- plastic skin, over-smoothing, HDR halos
- extra people, extra animals
- sudden cuts, multiple scenes (video only)
Do not paste a 200-word negative list. Long lists dilute the instructions that matter. Six specific failures are enough.

Frequently asked questions
Do these Halloween prompts work in Gemini?
Yes. Gemini can accept an attached image and a text instruction. Paste the prompt, attach the photo, and ask it to edit the image rather than describe it.
Do they work in ChatGPT?
ChatGPT image editing accepts a reference image and a prompt. Keep the preservation sentence at the top and ask for an image edit, not a description.
Why is the prompt so long?
Each sentence does a job: reference, preservation, costume, scene, camera, light and constraints. Removing the preservation sentence is the fastest way to lose the face.
Can I shorten the prompt?
Yes, but keep the reference and preservation sentences. The costume and scene can be shortened to one sentence each.
What is a negative prompt?
A list of things the model should avoid. Keep it short and specific to the failures you actually see.
Can I sell images made with these prompts?
Check the model provider terms and the game fan-content policy. Do not sell copies of another artist’s work or imply official endorsement.
