From Bulbapedia, the community-driven Pokémon encyclopedia.
Joe (Japanese: ジョー Joe) is a supporting character who appeared in Zoroark: Master of Illusions, and the grandfather of Karl. He is an old watchmaker who has lived in Crown City for his entire life.
Joe and Tammy, a close friend of his, were first seen fleeing from the intense flames left behind by an Entei by taking refuge in Tammy's flower shop. All the while, they were unaware that the Entei was actually an illusion created by a Zoroark. Joe later met up with his grandson Karl, and joined everyone back to Tammy's shop for tea. There, he explained the legend of the city's guardians, as well as the story of the disaster that befell Crown City twenty years prior. Tammy, like Joe, refused to evacuate like the other townspeople because they believed that the city's guardians would not seek to destroy Crown City, like the news had been claiming.
His suspicions proved to be correct, as he and Tammy later witnessed the real city's guardians battling against Zoroark. He then allowed Karl, Ash, his friends, and Rowena to take shelter from Grings Kodai in Joe's house. There, he revealed that he helped construct the Pokémon Baccer World Cup countdown clocks in the city. They soon discovered Kodai's scheme to steal the Time Ripple's power. Joe's information led Ash and his friends to the final countdown clock, hidden in the Pokémon Baccer Stadium gardens, where the Time Ripple was.
Joe and Tammy later joined Ash and his friends after they foiled Kodai's plot. He watched as Celebi made several plants grow before it time travelled away. He was then among those who confronted Kodai and witnessed his arrest by Officer Jenny. Afterwards, he joined Ash, his friends, and Tammy at the seaport to see Karl, Rowena, Zorua, and Zoroark set sail for the Unova region.
