I went into the Angel page and it said that Amenadiel, Lucifer, and Michael had chosen last names. What was the last name Michael choose? Cause I don't remember him having one in the show
I don't remember if they chose last names. Frankly speaking, Amenadiel, Michael, and the rest of the angels aside from Lucifer have one name. Michael's original name used to be Mi-ka-el which was used to rhyme with Samael, though he later changed it to Michael.
