The team first appears after the departure of Manaphy and appear to be friends of Wigglytuff. They ask Wigglytuff for a key that looks like an Unown but he does not remember until they 'boost' his memory with a Perfect Apple. Wigglytuff remembers then goes inside his room and potentially wrecks it. He comes back out with the key and is too preoccupied with the Perfect Apple to listen to Team Charm. They tell the guild about Aegis Cave and the great treasure inside. The partner asks if they can go before Team Charm leaves and spurs everyone else to ask as well. Everyone makes their way to Aegis Cave and Team Charm and the player's team unlocks the mystery by collecting Unown Stones and defeating the Legendary giants. Team Charm are always one step ahead until they are defeated by Registeel and thank the team. They offer to help them when they need it. They help the team defeat Regigigas along with four Bronzong and four Hitmonlee. The player unlocks the secret by uncovering the Concealed Ruins. Team Charm thanks them for the team's help and leaves, hoping to see the team again. They do not appear in the game afterwards and are only seen in the fourth Special Episode in Explorers of Sky.
This Special Episode shows their actual history, and they seem to be dedicated treasure hunters. It is also revealed that they were unwittingly involved with Time Gears.
Team Charm, like most characters in the games and anime, has a unique character that sets them above others. They are an extremely skilled group of girls, but their character is most important. Lopunny, who seems to have set herself as leader, seems to be somewhat vain, and obsessed with beauty. Medicham would be the strength, the Pokémon equivalent of brawn, while Gardevoir seems to be the brain, as the team's calm and strategic thinker.
Like the legendary Team Raider, Team Charm has achieved the Master Rank.
