Lava Beasts are monsters that appear in the cartoon series "Mighty Max".
Originally servants of Lava Lord, these creatures of molten rock became Skullmaster's slaves after he sealed their king in solid rock. After Max destroyed the Crystal of Souls, Lava Lord broke free from his prison and returned to lead the lava beasts against Skullmaster and his minions. They have made several appearances throughout the show - Skullmaster even sent one after Max in the first episode.
