A Behemoth is a Raid Boss which can be fought in Kingdom Hearts Unchained χ / Union χ. Behemoths can be encountered if a Raid Boss is triggered after playing Missions 1 through 34, or Missions 131 through 160. A popular method for spawning Behemoths is to play Mission 10 several times, due to the large number of Heartless available in that mission.

Behemoths Ω are rare and only have a small chance of spawning. They can be encountered after Missions 131-160
