The Brutal Five

The Brutal Five is an elite group of trainers, who arrived on Miryus along with its explorers.

They initially lived in towns, challenging other trainers and putting their battle techniques to shame so much that they decided to take a step back. They would allow only the most powerful trainers worthy of challenging them, until one day when their home was found empty. They went away through the island to discover the secrets of nature and growing stronger with their Pokémon, so the rumours say.
