Solid Twilight is best known for her destruction of the Elements of Heaven (killing Venom Twilight), and destroying the Elements of Zanzibar (supposedly killing Naked Twilight/ Big Boss). She has no family, and would rather be in Alaska preparing for the Iditarod. After destroying Shadow Moses, and learning she had a sister, Liquid Twilight (Liquid Snake x Twilight Sparkle x Applejack), she and a friend of hers started an anti-Metal Gear NGO, Elements of the Future.
