After the player has earned all eight Badges, Bede, who was chosen by Opal to be her successor, takes her place as the Ballonlea Gym Leader.
In the games
Ballonlea Stadium is the largest building in the town and is the site at which the fifth installment in the Galarregion's Gym Challenge takes place. It is located at the northernmost part of the town, across a wooden bridge crossing a small lake. Its exterior is primarily gray in color, with purple accents to signify the Fairy type. Like most Stadiums in the region, the Ballonlea Stadium contains a Poké Mart and a uniform shop.
The Gym mission is based on the premise that Gym Leader Opal is searching for a person to take her place as the Gym Leader so she can retire. In order for Opal to select a preferred candidate, challengers are made to undertake an examination as their Gym mission. The mission consists of three Trainer battles. At the end of each battle's first turn, the player is asked a question with two possible answers. Answering correctly results in a boost to some of the stats of the player's Pokémon, whereas answering incorrectly results in a stat reduction.
While pursuing Sordward and Shielbert, the player, Hop, and Piers will arrive at Ballonlea Stadium, only to learn that Bede has already taken care of most of the Dynamax Pokémon the brothers let loose in the Stadium. Before the player's group can leave, Bede demands a rematch with the player. After some assurance from Opal, the player will accept the challenge. After being defeated, Bede leaves to deal with the remaining Dynamax Pokémon at the Stadium.
