I’m sharing five trending Halloween coloring book subniches that are popping and people just can’t get enough of them.
AI-Generated Halloween Coloring Subniches: Grim Reaper
The Grim Reaper has always been known as the spooky symbol of death, but in this coloring book subniche, we’re giving it a softer twist. In this version, we turn the Grim Reaper into a cute and creative Halloween character.
It works especially well for older kids and adults who want something creepy but not too scary.

While the core look stays spooky, the cute add-ons keep it light and fun. Here’s where you can get creative.

Step 1: Keep the cloak, skull, and scythe as the recognizable base in a kawaii style.
Step 2: Swap props or add details like bunny slippers, a balloon instead of a scythe, or a pet cat by their side.
Step 3: Use these small changes to make the character more playful and fun.
