Trainers
If less than four players initiate a Max Raid Battle, a random selection of these NPC Trainers will populate the vacant positions. The level of their Pokémon is set to 70% of the host player's Pokémon (rounded down), hence a maximum of Lv. 70 if the host player's Pokémon is Lv. 100. KlaraSw, AverySh, and the Master Dojo Students only appear in the Isle of Armor, while Peony and Peonia only appear in the Crown Tundra.
Despite being depicted with Dynamax Bands, Klara, Avery and Peony will never Dynamax their Pokémon during a Max Raid Battle, nor will any other NPCs.
