Colby is married to the gym leader, Mavis, and their daughter is the gym leader, Velvet. Colby grew up with Mavis and the members of the elite four. Colby is very humble and easy going, so most people wouldn't guess that he's the pokemon champion. He also often leaves the pokemon league to visit his wife or his daughter, and often just leaves to escape his responsibilities as champion. However dispute his easygoing nature, he is extremely protective of others, especially his friends and family. He's slow to anger, but he's the last person that you'd want to piss off.
