Enzo Matrix is a sprite living in Mainframe. He is the son of Welman Matrix, the younger brother of Dot Matrix, and later the older brother to Little Enzo. When he was a young sprite his father was nullified when Mainframe's Twin City was destroyed. He lived with his older sister, Dot Matrix, at Dot's Diner. Enzo idolized Bob when the Guardian came to Mainframe to help protect the city. He was the envy of the little sprite and Enzo dreamed of being a Guardian just like Bob. Enzo's pet and best friend was a dog named Frisket. Despite his small stature Enzo was very brave, always ready to go into a Game Cube or face Megabyte or Hexadecimal. Enzo also had a habit of greeting Bob by tackling him to the ground.
