The Grim Reaper
There is no right or wrong when it comes to depicting the very image of death. They could be a skeleton with a scythe, a wolf with two sickles, a genderfluid feline with a book, or just a simple angel of death, but they are all the same to the Grim Reaper because eventually Death comes for us all.
However, one has to consider Death’s feelings on the matter of being the Grim Reaper; it sounds like an easy job to simply take souls. But to Death they grow tired of hearing the same screams, the same pointless lines of dialogue, the fake promises, and they grow tired that all mortals don’t see everything they do against the Grim Reaper is inevitable. However, that changes the very moment they meet their next target, which is our next character.
