Fiend Listing - Monster Arena

Monster Arena > Omega Ruins > Puroboros

HP: 20,000

Puroboros is a Bomb-type enemy that can be found in the Omega Ruins. You need to capture five of each Bomb-type enemy in order to unlock Bomb King in the Species Conquest section of the Monster Arena.

Puroboros, like the other Bomb-type enemies, will grow larger in size up to three times, and if not defeated, it will explode for a fair bit of damage. Defeat it as quickly as possible by focusing your attacks on one Puroboros before moving on to other fiends. These enemies are relatively easy to defeat.

Kimahri can use Lancet on a Puroboros to learn Self-Destruct for his Ronso Rage Overdrive.
