Shadow Peach

While possessing Peach, the Shadow Queen looks like the princess: her skin turns darker, her dress becomes black with white details, and she now wears a cloak (black with white details as well) with a high collar. Her crown and her jewelry take new shape and are red now. The Shadow Queen is shown to be a ruthless, vain, hardened, dark, and cruel tyrantess who cares for nothing but herself or her desire for power and control. She is a highly power-hungry and ruthless demon whose actions have led to the destruction of entire lands and the murders of millions. She is shown to be one of the (if not the) most disturbing and immoral villains within the series and doesn't demonstrate any kindness or care for anything or anyone, even those who did favors for her, as she killed Sir Grodus knowing that he resurrected her. Many of the monsters Mario fought were part of her army, and her most loyal followers were the ones manipulating the course of events to revive her, in which they succeeded.
