The battles have begun in the 2017 No Holds Barred Online Competition. In the latest competition, Pokémon Sun and Moon players get to use a huge variety of Pokémon, and limits such as duplicate Pokémon and items have been lifted. It should be an all-out brawl to see who reaches the top of the standings! Registered competitors can battle up to 15 times per day. The competition concludes on Sunday, August 27, 2017, at 23:59 UTC. If you missed the chance to register and battle in this competition, keep checking the Pokémon Global Link for more opportunities to battle.
