Darkness Beasts

The Darkness Beasts are entities (or one entity, with multiple bodies) that dwell in the lowest levels of Mount Moon.

History
The Darkness Beasts may have existed for an unknown amount of time before Rose, Cobalt, and Victor entered Mount Moon. While they were there, the Beasts caused a rock slide that trapped Baritone and his mother, and then attacked the mother, killing her. When Rose and Cobalt entered the level of Mount Moon where the rock slide happened, the Darkness Beasts were in the process of attacking the Mysterious Egg, guarded by a Clefairy. When Rose and Cobalt rushed to defend the two, the Beasts were able to kill the Clefairy, before being driven off by...something.

Rose, Cobalt, and Victor warned a group of excavating scientists about the Beasts, and later informed Professor Skye about their existence.

Their current whereabouts, status, and activity are all unknown.

Description
The Darkness Beasts are probably every Trainer's worst nightmare. They may not even be Pokémon.

Physically, they appear as a dark, constantly shifting and changing mass that is capable of independent motion. All Beasts have multiple eyes of differing colors.

The Beasts encountered in the depths of Mount Moon were apparently invulnerable to Pokémon attacks, as Minuet's Sleep Powder and Bango's Ember had no effect on them.
