Worm MR1

Worms resemble their namesake, only they have large tusks and a stinger that can be poisonous. They are experts at burrowing, and although they are not high in intelliegence, Worms are some of the most loyal monsters.

In Monster Rancher 2, Worms could become large, beetle-like monsters known as Beaclons. This is considered a separate breed, and it has been featured instead of Worm in Monster Rancher 3, Monster Rancher 4 and Monster Rancher EVO. Worm finally made a comeback in the Online game installments.

In order to enter the metamorphosis in Monster Rancher 2, the Worm must have lived to be at least four years of age, have little to no stress, 80+ loyalty, not be raised spoiled or strict, and must be under B rank. If all of these conditions are met, the Worm will wrap itself in a cocoon on the 4th week of June. The next week, the Worm will emerge as a random monster with a Worm sub-type.


Named for being a worm, though it resembles a caterpillar more.
