A rebel angel
Aziraphale is one of the main characters of the Good Omens series, adapted from the famous novel by Terry Pratchett and Neil Gaiman. Aziraphale is an angel who was there at the time of the creation of Adam and Eve and at the time of their temptation by the demon Crowley with whom, against all odds, he became friends. Since the creation of men, both spent most of their time on Earth and got used to it very well. Aziraphale is particularly fond of books and runs a bookstore, and he is also very fond of earthly food. So when it is announced that the antichrist will soon be born and eleven years later trigger the apocalypse that will settle the conflict between heaven and hell once and for all, the two friends are not exactly thrilled. So they decide to agree to do everything to prevent the child in question from reaching his destiny.
