Presenting my version of the Grim Reaper.
Everyone has an appointment with her. She is a constant multiversal force of nature. But, even she cannot break certain rules, such as influencing herself onto life. Over the ages, she’s developed an affinity for the human race and started finding out what makes life tick since she knows what makes it stop doing so.
With her fellow Horsemen of the Apocalypse, she helped the Vortonians create the idea of a transformation belt. She, War, Pestilence, and Famine then started a school for both living and dead to attend called After Academy. She had many students throughout her existence, offering them a chance to learn from her whether they’re alive or dead. Her recent student, Lacey, is learning more than the average student so she could become the fabled Fifth Horseman of the Apocalypse, Kamen Rider Apocalypse.
After hearing about Vortech rising and getting his hands on the Foundation Elements, Death built her own transformation belt, the Mortem Driver to become Kamen Rider Death. She made three more after that and now trains Lacey on top of her own duties.
She’s actually very sociable and loves the Discworld series by the late Sir Terry Pratchett. He was one of the few that followed his crest, Non Timetis Messor (Don’t fear the Reaper).
