Behemoth King

Behemoth King is a more challenging version of Behemoth. He is fought when the players' team beats the Final Fantasy team (consisting of either just White Mage and Ninja when playing with 2 characters, or both with Black Mage when playing with 3 characters) and obtains the luminescent crystal. The events that follow this are not too similar with the precursor to Behemoth; once the crystal gets placed, it turns dark and drags the ship into a portal, which the players' characters encounter. The crystal materializes into Behemoth King instead of Behemoth however.

Behemoth King has a slightly different attack pattern and is more resilient to attacks than Behemoth. Other than this and his color swap, there is little to no other difference to Behemoth.
