Description
Legendary Pokémon Groudon and Kyogre join the clash in the Primal Battle Online Competition! In addition to the Pokémon that are typically allowed, Groudon and Kyogre could also be included on a players team. All battles were Double Battles using Pokémon Omega Ruby and Pokémon Alpha Sapphire. Players weren't allowed to bring in Pokémon from past games via Poké Transporter.

The competition used the Double Battle format and players could register 4 to 6 of their level 1–100 Pokémon to their Battle Box. Pokémon automatically became Level 50 during battles. A 20-minute time limit for each match was automatically enforced in-game, beginning at the start of each battle. If the outcome had not been determined when the time limit expired, the game automatically applied tiebreakers to determine a winner. At the beginning of each battle, players had 90 seconds to select their Pokémon to battle with. At the beginning of each turn, players had 60 seconds to select a move or change Pokémon in battle. If a player had not made his or her selections at the end of this period, the game automatically made selections for the player. Players could battle up to 10 games per day of the competition. Any unplayed games would carry over to the following day.
