It has a 66% chance to use Lifeshaver on its second turn, and may do so twice. On the third turn it may use its special, Heave, a powerful attack. On its fourth and fifth turns it has a 33% chance to use either Atomic Rays, Lifeshaver, or Heave. Since they often attack with a Great Malboro, which use Bad Breath when alone, the Primeval Dragon should be killed last. Blizzaga attacks work well against it.
