Hisanmon is a Mutant Digimon whose name and design come from "Misery (悲惨 Hisan?)." Said to have been born from pure misery, Hisanmon is said to be unable to feel positive emotions. It wanders the Digital World, seeking those with troubled hearts so as to prevent them from experiencing the misery that created it, as well as giving misery to those who deserve it. One look into its eyes is said to haunt you with all of your wrongs.
Hisanmon resembles a 32-year-old man wrapped in a tattered gray cloak. It never removes said cloak, so what its body looks like is unknown. It has long gray hair and soulless orange eyes that have frighteningly large pupils.
- Haunting Gaze: Flashes its eyes orange, bringing back memories of all the wrong the target has done, leaving them in a comatose state, their eyes becoming like Hisanmon's eyes.
- Heart Healer: Flashes its eyes pink, soothing the target of any misery that ails it. This also undoes the effects of Haunting Gaze.
