Battle FrontierPower Keepers #71 Pokémon Card

Battle Frontier is not a Pokémon species but rather a location and concept within the Pokémon world, first introduced in the Generation III games, Pokémon Emerald. It serves as an ultimate challenge for trainers who have conquered the regional Pokémon League, offering a variety of distinct battle facilities, each with its own rules and Frontier Brain to defeat. These facilities, such as the Battle Tower, Battle Factory, Battle Arena, Battle Dome, Battle Pike, Battle Pyramid, and Battle Palace, test different aspects of a trainer's skill, from strategic team building to quick decision-making. The concept of the Battle Frontier was highly popular among fans for providing extensive post-game content and a rigorous test of competitive battling prowess, fostering a deeper engagement with the game's mechanics beyond the main story. Its reappearance in Generation IV's Pokémon Platinum further solidified its status as a beloved staple for hardcore trainers, though it has been notably absent from subsequent main series games, leading to frequent fan requests for its return. The artwork on this card depicts a bustling, diverse landscape that embodies the spirit of a grand challenge facility, featuring various architectural styles and natural elements that hint at different arenas or areas within a sprawling complex.
