A great Batman TAS Jervis Tetch x Reader fanfiction is one that can make you feel like you're part of the story. The writer should use vivid descriptions, not just of the physical appearances but also of the emotions. The story could incorporate some of the iconic elements from Batman TAS, like the art style or the other characters. This adds depth to the fic.
