Mustard

Core series

• In the past, Mustard used to be a Fighting-type Gym Leader . He became the Galar League Champion soon after a heated battle with Opal about 50 years prior to the events of Sword and Shield , a position which he managed to hold for 18 years, longer than any other League Champion before or since. He only lost the title after his prowess in battle began to wane following the death of his partner Pokémon. After refusing a suggestion by the then chairman of the Galar Pokémon League to have a match rigged in his favor, Mustard retired from the Galar League entirely and traveled around the world , until he bought an unnamed island off the coast of Galar and named it the Isle of Armor , setting up his Master Dojo there to teach people about Pokémon battles . One of his students was Leon , who would go on to become a Champion himself one day as well, despite failing to finish Mustard's training due to his horrible sense of direction preventing him from finding the Towers of Two Fists .
• Upon arriving at the Master Dojo, Mustard accepts the player as his student and has an easy battle with them. He then puts all of his students through three trials, with the player ending up as the winner and earning a Kubfu as a gift from Mustard. After befriending Kubfu, the player must evolve it at either the Tower of Darkness or the Tower of Waters , depending on their choice, with Mustard acting as the final opponent before Kubfu can evolve into Urshifu . Once the player has successfully found a way to unlock Urshifu's Gigantamax potential, Mustard will challenge the player to one more battle, where he holds nothing back. After this battle, he can be challenged to a rematch once a day if the player talks to him while he plays Pokémon Quest in the Master Dojo.
• This is a transcript of the back of Mustard's League Cards in Pokémon Sword and Shield .
• Normal League Card "Mustard is the former Fighting-type Gym Leader and is regarded as one of the strongest Champions in Galar's history—reigning undefeated for 18 years. His intense drive for strength meant he insisted on discipline, both in himself and in others. His character changed drastically, however, after his post-retirement globe-trotting. His sudden purchase of a deserted island added to the surprise of those around him. When asked for his reasoning, he answered with a smile, "There are lots of ways to be strong in this world. I want to see them all!" The name "Isle of Armor" was also his idea." Rare League Card "This photo was taken about 50 years ago, when Mustard defeated the Fairy-type Gym Leader and went on to become Champion. He reigned undefeated until he lost his partner Pokémon. After this, his losses started to mount. He remained popular even after losing the mantle of Champion, but decided to retire after the league chairman at that time asked him to win in a rigged match. Mustard developed an obsession with video games after his retirement. Apparently he held off while he was still active in order to maintain his image to his fans."
• Mustard keeps his Pokémon in Ultra Balls .
• Mustard will Gigantamax his Urshifu at the first opportunity. After completing the Galarian Star Tournament , his Pokémon's levels will increase.
• Mustard uses these three Pokémon as both a partner and potential opponent in the Galarian Star Tournament .
• Mustard gives this Kubfu to the player once they have cleared his three trials.
• Mustard also owns three fast Galarian Slowpoke that are used in the first trial of the Master Dojo. All three Slowpoke have 31 IVs in HP and Speed , with 252 EVs in HP and Speed and 6 EVs in Special Defense . They also start the battle with a +6 stage boost in Speed. While these Slowpoke are treated as wild Pokémon encounters, none of the three can be caught.
