Behemoth first appeared in "The Million Dollar Ghost." At the beginning of the episode Vlad tried to gain the Skeleton Key, however before he could, Behemoth appeared and the two battled. Vlad managed to gain the upper hand and he and his duplicates ensnared Behemoth. It looked like he was going to win, when Behemoth managed to break free and knocked Vlad and his Duplicates back out of the Ghost Zone. Vlad got up and the two faced each other, ready to continue fighting, when Vlad's "Change the Ecto-Filtrator" alarm started going off. Behemoth left, shortly before the portal exploded.
At the end of the episode Vlad returned weakened and injured by accident, and grabbed the key, as he was gloating to himself about his victory Behemoth returned and then ate him, as he was too weak to fight back.
