Name the build
Round shoulders, heavy middle, short legs. Plain words keep the model from drifting back to a slim default.

Keep the Same Man in Every Scene
Keep the face and the build locked
Step 1
Fix the build first
Say the body shape in plain words: round shoulders, heavy middle, short legs. Vague prompts drift back to a generic slim figure.
Step 2
Add a job and a prop
Apron, guitar, clipboard, dog lead. A prop gives the hands something to do and stops the arms hanging loose.
Step 3
Lock the face
Reuse the same face description across scenes, then switch to image-to-image so the second picture keeps the first one's head.

Six decisions that keep one character recognisable
Posture sells it
A lean, a crouch or a raised fist gives the body a line. Standing straight on hides the shape you asked for.
One prop at a time
A guitar, a tray, a leash. Props explain the pose and give the fingers a defined job.
Dressed, always
Every prompt keeps the character fully clothed. It keeps the output usable for games, comics and client work.
Face lock
Write one face line and paste it into every prompt, then use image-to-image to carry it into the next scene.
Flat colour wins
Cartoon shading holds up at small sizes and stays consistent. Photoreal skin drifts between passes.
User Feedback

I needed a everyday jobs concept the same afternoon I found this page. I typed what I wanted for "Cupcake Tower", ran it twice, then changed only the light and the palette on the second pass. The version I kept went straight into a client deck and saved me a stock-photo search.

My first try for "Mail Route" came back too polished, more advertising than real photograph. I rewrote the sentence to describe the surface and the actual light in the room, and the third attempt looked like something I could have shot myself. That is the one I still use for ai fat man generator mockups.

I use it the way I use a sketchbook: one prompt for "Dented Armour", one for "Pirate Helm", then I pick the half that works and iterate from there. Two of those frames ended up in a package for a client who could not decide between the two directions, and seeing them side by side settled it in a minute.

Heavier Body, Same Face
With a reference photo, yes, and the build changes more reliably than the face. Ask for the same face with a heavier build, and lock hair, beard and gaze so the model spends its changes on the body.
Models exaggerate whatever trait you name. Add constraints that belong to a real person: posture, how the shirt fits, an occupation, a room. Ask for a natural-proportion editorial portrait instead of a funny one.
Only with their agreement. An identifiable person in a body-altering image made without consent is harassment in most workplace and platform policies, and several platforms will remove it.
Upload the reference, describe the body in plain measurements of shape rather than adjectives, and change nothing about the head. Neck and jawline are where identity breaks first, so ask to keep the jawline intact.
