In addition, Sōdo is a (Japanese: 身具職人Tool Meister). His job is to repair various objects Pokémon use as weapons in battle, such as his Sirfetch'd's leek sword or his Grookey's stick.
Sōdo was first seen rescuing a young boy named Marvin from falling off a cliff. Later, Marvin was taken to Sōdo by Shirudomiria in order to properly thank him for saving his life earlier. After a brief introduction, Shirudomiria offered to let Marvin participate in a Dynamax simulation with her and Sōdo. Together, they fought and defeated a Dynamax Pangoro hologram, giving Marvin the confidence to set out on a Pokémon journey. Having received approval from his parents, Marvin joined the others on their quest to study Dynamax.
Later, everyone found Leon on the outskirts of Wedgehurst, trying to move a large flock of Wooloo off of some train tracks. Sōdo and Shirudomiria stepped in to help, driving off an Obstagoon that was terrorizing the Wooloo. After introducing themselves, Leon left to appear on a television program in Motostoke. To Marvin's surprise, Sōdo and Shirudomiria revealed they helped Leon hoping that their efforts would leave enough of an impression that he'd give them an endorsement for the Gym Challenge.
Later, the trailer house was attacked by a trio of wild Drednaw. In order to battle the Bite Pokémon, Sōdo and Shirudomiria each received a Rotom Phone with a Pokédex function installed, officially making them both Pokédex holders. With some assistance from Sobble, the Drednaw were defeated. Afterward, Professor Magnolia suggested Marvin keep Sobble, which he happily accepted.
Sirfetch'd is Sōdo's first known Pokémon. It was first seen being used to rescue Marvin from falling off a cliff.
