88

The Ultra Guardians act to defend Lunala from a strange entity that pursued it via an Ultra Wormhole. This creature, later named UB Black by Lusamine, siphons energy from Lunala’s Ultra Aura and attaches to the Legendary Pokémon to absorb its power. The heroes intervene and repel the threat with assistance from Solgaleo. However, the entity subsequently targets Solgaleo, draining its energy before fleeing through another Ultra Wormhole.
