A Guard Armor is a Raid Boss which can be fought in Unchained X. Guard Armors can be encountered if a Raid Boss is triggered while playing Missions 35 through 66, or Missions 170 through 188. A popular method for spawning Guard Armors is to play Mission 57 three times, due to the large number of Heartless available in that mission. Rare Guard Armors can be encountered on Mission 170, 174, 180, 183 and 266.
