Batman/Teenage Mutant Ninja Turtles

The mashup feels so seamless and fun — I wonder if it was an organic idea or a carefully planned crossover. What inspired this unique collaboration?

At times, the story balanced serious themes with humor, which made me curious if maintaining that tone was a challenge during writing.

Some moments felt like pure fan service, but I’d love to hear if there were particular character pairings that sparked inspiration or fun for the creator.
