How to Make a Stunning Comic with Nano Banana Pro Prompts in 2025

Part 1. Is Nano Banana Pro Actually Free?

Short answer: yes, but with limits that make sense.

Right now (November 21, 2025), anyone with a Google account can jump into the Gemini app or AI Studio and start making Nano Banana Pro comic strips for free. You get a decent daily quota in “Thinking” mode — enough for 20–30 solid strips if you’re not spamming. Once you hit the cap, it drops you back to the older Nano Banana model, which is still good but nowhere near Pro level for comics.

Want unlimited? Gemini Advanced or the new Ultra tier removes the ceiling completely. Most serious creators I’ve seen on Reddit and X upgraded the same day because the difference is night-and-day for character consistency across panels.

Part 2. Step-by-Step Guide: Create Character Interaction Comics with Nano Banana Pro

Here’s exactly how I made the dog-vs-cat strip that’s now my phone wallpaper.

1. Open gemini.google.com or the mobile app → switch to “Gemini 3 Pro (Thinking)”.
2. Upload reference photos. I dropped in one clear selfie of my dog and one of my cat.
3. Use a numbered prompt (this is the trick everyone on X is sharing):
   “Create an 8-panel Nano Banana Pro comic in bold Marvel style, thick black inks, vibrant colors, perfect speech bubbles.
Panel 1: Dog sitting on couch, smug expression, bubble: ‘I’m clearly the favorite.’
Panel 2: Cat jumps in frame, tail puffed: ‘Keep dreaming, slobber machine.’
…continue the argument until panel 8 where they both fall asleep leaning on each other, tiny heart above.”
4. Hit generate. First try gave me 90% perfection. I just typed “make panel 6 more dramatic low angle” and it fixed it instantly.

That’s it. Ten minutes from idea to finished strip. The Nano Banana Pro comic generated figurine pictures are so realistic that my friend thought I paid an artist on Fiverr.

Note:

Always number your panels.

Add “consistent character design across all panels, exact same face” if you’re doing a series.

Throw in “SFX in comic font” for those sweet POW! and THWAP! sounds.
