Angel: "I am God."
Alexandra is not a nice person. She is a stickler for the rules and a religious fanatic, which is something that people don't normally realize at first because she keeps so much of her thoughts and actions to herself. She believes that the angels have been deprived of heaven, and that some major changes need to occur in purgatory in order for the angels to reach heaven. Interestingly, she doesn't actually believe in God, because she believes that all angels, collectively, are God. Therefore, she tends to view angels as dethroned kings and queens deprived of their right to rule.
Shockingly, she is not that fun to hang out with. She has no sense of humor. She does not yell when she's angry, but she will be so cold that you may freeze on the spot. She's also extremely conniving, tends to view people as "enemies" or "people not worthy to be enemies" and she will do absolutely anything to destroy an enemy. She has more enemies than not, although most of her enemies would be shocked to discover that they are actually her enemies.
Alexandra comes from a long line of distinguished angels, and she adopted their snobbery in every way. During the great angel migration, she was one of the few angels who wanted to stay in purgatory. Eventually, she relented, and for a short period of time she lived on the floating island of Heaven. However, she eventually relocated back to the Bureau. Even though she is hard to get along with, most people are grateful that she chose to work for the Bureau when all the other angels were essentially sticking their heads in the sand. Little did they know that Alexandra did not come back to help the Bureau or, by extension, purgatory - she came back to conquer it. She has apparently never read any history books, or she would realize how futile her endeavor is.
Recently, she came into a strange power that no one else knew about. But what will she use it for...?
