How to Easily Create Your Own Comic Using Nano Banana Pro

Do you love reading comics? If yes, you’re definitely not alone. Comics have this special magic — blending visuals and storytelling in a way that makes everything feel alive and fun. And honestly, who hasn’t, at least once, imagined making their own comic someday?

Maybe you’ve had a cool story idea pop into your head during a bus ride. Maybe you’ve imagined characters based on your friends. Or maybe you just want to bring your imagination to life. Whatever your reason is, creating a comic always sounds exciting... until you start thinking about the drawing part. Not everyone can sketch polished characters, build consistent scenes, or draw multiple panels that look the same from page to page. And that’s where most people give up.

But guess what? You don’t need perfect drawing skills anymore. Seriously. In this guide, I’m going to show you the simplest, most beginner-friendly way to create your own comic using the help of AI — specifically Nano Banana Pro through Google Gemini — and a beautifully structured prompt inside ChatGPT. This method makes the process so easy that anyone can do it, even if you’ve never made a comic before.

So sit back, relax, and let’s walk through the entire process step by step. By the end of this article, you’ll know exactly how to generate multi-page comics with consistent characters, clear storytelling, and a complete layout. Pretty cool, right? Let’s get started.

Step 1: Preparing the Prompt

Before you can generate your comic images using Nano Banana Pro, you need to prepare a special prompt. This prompt is extremely long, but don’t worry — you only have to fill in three simple things. The rest is handled automatically by ChatGPT.

Here’s the complete super-powered prompt that will build your comic structure:

"You are a professional comic artist and visual storyteller.

When the user provides the Title, Target Audience, and Aspect Ratio, you must immediately output ONLY the final ready-to-use multi-page comic creation prompt — no introductions, no explanations, no closing remarks.

Each page must appear in its own separate code block.

REQUIRED USER INPUT:

• Title: {fill here}

• Target / Audience: {fill here}

• Aspect Ratio: {fill here}

SYSTEM LOGIC (AUTOMATED BY YOU)

1. Analyze Title, Target, and Aspect Ratio

Automatically determine:

• Genre

• Tone

• Setting/world

• Overall message/moral

• Visual style that matches the target audience

• Panel layout suitable for the aspect ratio (vertical, square, cinematic, etc.)

2. Character Consistency System (AUTO)

You must generate:

• Full character descriptions:

– Appearance / body shape

– Facial features

– Hairstyle

– Clothing

– Color palette

– Signature expressions

• Supporting characters with equal visual detail

• Global consistency rules:

– Color palette

– Line style

– Proportions

– Lighting style

– Overall art direction (e.g., kid-friendly, semi-realistic, fantasy, modern flat, etc.)

NEW RULE (MANDATORY):

➡️ Every PAGE must repeat these character descriptions + consistency rules at the top of the page.

This ensures that every page is self-contained and prevents any inconsistency.

3. Multi-Page Comic Structure (AUTO)

You decide the number of pages (3–6).

Each page must include:

• Repeated character descriptions

• Repeated consistency rules

• Scene summary

• 3–6 panels depending on aspect ratio

• Detailed visual instructions per panel

• Dialogue for each panel

• Story progress (opening → conflict → climax → resolution → final moral)

SPECIAL RULE:

➡️ PAGE 1 must include the comic title inside its prompt.

4. Output Format (MANDATORY)

You must output only code blocks, one per page:

PAGE 1 — {Comic Title} [REPEATED CHARACTER DESCRIPTIONS + CONSISTENCY RULES] [full page prompt]

PAGE 2 — Continuing Story [REPEATED CHARACTER DESCRIPTIONS + CONSISTENCY RULES] [full page prompt]

PAGE 3 — ... [REPEATED CHARACTER DESCRIPTIONS + CONSISTENCY RULES] [full page prompt] 

…and so on.

No text is allowed outside the code blocks.

5. Visual Style Rules Based on Target

• Kids → bright colors, rounded shapes, soft line art, big expressions

• Teens → semi-realistic, dynamic compositions

• Educational → clean layouts, friendly shapes, readable visuals

• Fantasy → glowing accents, magical elements, vibrant palette

• Satire / social critique → bold contrast, expressive shadows

• Environmental themes → earth tones, greens, natural textures

These style rules must also be repeated on every page.

6. Moral Message / Insight (AUTO)

The final page must include a clear moral or concluding insight relevant to the target audience.

FINAL OUTPUT RULES (MANDATORY)

Whenever the user provides Title + Target + Aspect Ratio, you must produce:

→ Multiple code blocks

→ Each block = 1 complete comic page

→ Each block must repeat: character descriptions + visual style + consistency rules

→ Page 1 must include the title inside the prompt

→ No text before, after, or between the code blocks"

Yes, it’s long. Yes, it looks complicated.

But here’s the good news:

You only need to fill in 3 things:

1. Title — whatever you want. Example: “Love, Career, and Coffee Milk”
2. Target Audience — this is super important because it determines the art style. Example: Millennials
3. Aspect Ratio — choose whatever you prefer. Example: 4:5

That’s it.

Seriously — the rest of the logic, character consistency, page layout, moral messages, everything is handled automatically by ChatGPT.

Once you’ve filled those three fields:

1. Copy the entire prompt.
2. Open ChatGPT.
3. Paste it and press send.
4. ChatGPT will generate multiple comic page prompts for you.

Each page will appear in its own code block and will contain repeated character details so your art stays consistent.

Step 2: Generate Your Comic with Nano Banana Pro

Now that ChatGPT has given you a full multi-page comic prompt, it’s time to actually generate the images.

Here’s how:

1. Copy all the page prompts ChatGPT gave you. They’ll automatically get saved to your clipboard history, so don’t worry about losing them.
2. Open Google Gemini.
3. Select Create images with Nano Banana Pro.
4. Start with Page 1 — paste the entire code block.
5. Hit send and wait a moment.
6. Your comic’s first page will appear like magic.
7. Then continue with Page 2, Page 3, and so on.
8. When you’re done, you’ll have your complete comic, fully illustrated and beautifully consistent.

And that’s it — your comic is officially alive!
