Just as Absol are noted around the world for appearing before a disaster comes, Brionne are known across Alola for arriving in the aftermath. Their presence in Alola was first recorded not long after the island's first inhabitants felt the wrath of their guardian spirits, when people noted a pod of Brionne dancing and playing in the ruins. At first the colonists were befuddled, for they wondered how anyone could sing and dance after such a tragedy – yet in between mourning the dead and rebuilding, they crept away to watch, and a few humans even joined in.
Some have hypothesized that Brionne did this because they are a colonist species, and have cause to assemble at and celebrate either the mist or the volcanic ash which frequently follows tragedy in Alola, but even most scientists prefer the traditional explanation: Brionne sing and dance, despite the pain, so that they can lift the spirits of the survivors.
The decline of the wild Popplio population left no wild Brionne to travel of their own accord – but they perform at concerts in the aftermath of tragedy all the same. Brionne today are known for accompanying idols and singers, and their strange pokemon music supplements many a beloved performer in Alola. Many historians note that the social role of idols, who strive to use song and dance to bring happiness to the people, was once fulfilled exclusively by these pokemon. In this era, it is the Brionne who bring their trainers to spots of tragedy, and push them, when they find themselves overwhelmed by sorrow, to smile and cheer up others.
