Main article: Avatar Color Duel Avatars come in many shapes and sizes, but on the whole tend to be either humanoid or animal-shaped. Each Duel Avatar is named with a color and a noun, such as Lime Bell or Peach Parasol. Both the color and the noun designate the Duel Avatar's general abilities. Rarely, a Duel Avatar will be created with a so-called "metal color", which gets its properties from the metal it's named after instead of a color, such as Silver Crow or Nickel Doll. On some Duel Avatars, the first prefix may not appear to be a color, such as Ardor Maiden, but "ardor" refers to a blazing flame and is used as a color to mean red and white.
