20 Nano Banana Pro Prompts for Character Design

Character design used to require hours of sketching, multiple iterations, and serious artistic skill.

Now Nano Banana Pro can generate complete character sheets with turnarounds, expression variations, and costume designs in minutes.

Before we get into the prompts, let’s address the elephant in the room.

A Quick Note About AI and Artists

Some people hate AI image generation because they worry it replaces artists.

Here’s my take: these tools don’t replace character artists; they help people who can’t afford to commission artwork or need quick concept visualizations.

Professional character designers still do the refinement, personality development, and final production work that AI can’t touch.

Think of these prompts as concept sketches, not finished professional work.

If you’re creating something commercial or serious, hire an actual artist for the final designs.

But for personal projects, indie games, writing references, or just exploring ideas? These prompts work great.

Who Can Use These Character Design Prompts?

These prompts are useful if you’re:

• A writer visualizing characters from your novel or screenplay
• An indie game developer prototyping character concepts on a budget
• A dungeon master creating NPCs for your tabletop RPG campaign
• A content creator needing character references for storytelling
• Someone learning character design principles and studying different styles
• An artist looking for initial concept inspiration before refining by hand

Basically, if you need to see what a character looks like before investing in professional artwork, these prompts give you a starting point.
