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, or both with Black Mage) 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.
