Shao Kahn's Helmet or Shao Kahn's Mask, sometimes referred to as the Mask of Shao Kahn, is an ancient spiked, samurai helmet guise carved out of bone and worn by the vicious warlord Shao Kahn the Konqueror, and it is the symbol of his own ruthless empire in the realm of Outworld. Shao Kahn's own "crown" which conceals his face first appeared in Mortal Kombat II along with him, though it has taken each different shape and form throughout the Mortal Kombat series. It also became as an another collectible relic within the Konquest mode of Mortal Kombat: Armageddon.
