Zachary Ketchum, or called Zach by the family, is a six-year-old an aspiring Pokémon Trainer. He is the younger brother of Bailey Ketchum and Ash and Serena Ketchum's younger child and only son.
While Bailey takes after their mother, Zach takes after their father, having his spiky black hair but Serena's blue eyes. He wears a blue t-shirt, a pair of shorts and black and red sneakers.
Just like he takes after his father in appearance, Zachary takes after his father in personality as well, but not an extreme. Like his father, Zach has a strong sense of justice, especially with Pokémon. Despite his age, Zachary is slightly much more smarter than his father when Ash was his age. Zachary cares and loves all Pokémon, and when he's stuck at home will always been seen taking care of his parent's Pokémon, usually with Pikachu watching over him especially when he's near Ash's 30 Tauros.
Due to not being the right age to be a Trainer, Zachary isn't able to raise his own.
