The Behemoth is the matured, larger, more powerful form of the Mauler, distinguishable for having grown prominent horns that it uses to balance itself as though they were a tail. It is believed these horns can sense subtle vibrations in the environment, and thus potential threats to the pack. The skin develops several more layers as the creature matures, slowing the creature down, although it is capable of short bursts of speed when it jumps or charges. Its jaw has continued to grow to unnatural proportions, granting it a number of more teeth. With no indication this growth ever stops, it's possible it eventually leads to the Behemoth's death.
