My Oc Black Widow , she is one of the four ponies of the Apocalypse of my fanfic , Death.

It’s called Black Widow for it for more than it was death she should fulfill her duty , but she loved life and thought very important , it is good or was until then, she also loved her at first, but when I tried to keep contact with some being the same had just died , she lives in the dimension of the dead, but when it comes into contact with the living it becomes visible to them, many died because she want to have a love, and the few who survived reported a pony black mane with dead appearance , legend has spread and the touch of death in love with killing those who tried it love gave him the name of black widow .

She did not want to have to take these lives of those who love , making love and feelings aside , becoming cold and unfeeling death.

To be death , I believe it makes sense to be a alicorn

His appearance in the fic amid Apocalypse brings the dead back to life, destroying the creation along with Famine, Pestilence and War.
