I had a thought

Once Holly unchains the Loyal Three, how is she going to get their powers back?

She takes three evolutionary stones to the moon pool. A Moon Stone, a Fire Stone, and a Thunder Stone.

She dunks them in, and when she takes them back out...they've all been blessed with Star Clan's magic.

Taking the Blessed Fire Stoneto Fezandipiti results in a fiery aura surrounding where his chains once lay, with him now being a Fire/Fairy Pokémon.

The Blessed Moonstone goes to Okidogi. His muscles return, and he bow had a 'chain' made up of amethyst geodes. He is also now a Rock/Fighting type.

And last but not least, Munkidori gets the Blessed Thunderstone. Sparks surround his head, granting him back the intelligence he once had. He is also now an Electric/Psychic type.

Just a thought.
