Personality Description
TK is a cheerful and amiable person. He doesn't like seeing anyone upset and will always try to cheer them up. He enjoys making people smile. In Digital World Adventures Part I, he was a crybaby due to being a young child. But in Part II, he was shown to have matured a bit being a preteen. His parents divorced when he was very young and his older brother, Matt went with their father while TK stayed with their mother. TK doesn't remember too much of his parents' divorce and is used to it thinking it was always that way. He went to summer camp with Matt on a special arrangement made by their parents. He and Matt along with the other Digidestined were chosen to become Digidestined. TK doesn't like to see anyone abuse the powers of darkness and will confront them due to almost being killed as a child and watching Angemon, Patamon's champion form die right in front of his eyes. Because of this, he is very protective of Patamon and gets angry whenever Patamon's life is threatened including when Ken tries several attempts to turn Patamon into his slave.
