A Perfect-level Fallen Angel Digimon. It used to be an Angel Digimon like Angewomon, but was tempted over to the side of evil and fell down as a result. Lady Devimon is the female counterpart to Devimon; curiously, the latter is only an Adult-level Digimon.
Lady Devimon's main Adult form is Black Tailmon, and its main Ultimate form is Lilithmon. It can Jogress Evolve with Angewomon to become Mastemon.
