"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 had an interest in video games when active, but it is not known if it was before or after he lost his Champion title. In any case, it developed into an obsession, implying that it is unhealthy, after he retired. The league cards only indicate a portion of the story, however. Mustard named the island "Isle of Armor," presumably because he used the island to hide away from the world as his armor, not wanting to suffer more from his partner's death.
