Little Enzo Matrix is a young sprite living in Mainframe. He is the youngest son of Welman Matrix, and he has two older siblings, Dot Matrix, and Enzo Matrix. Little Enzo is a program copy of his older brother, the original Enzo Matrix. When Mainframe crashed Phong scanned all active icons in the city so that everyone would be backed up. Some people that had been deleted still had their PIDs on file so they were backed up as well. The original Enzo had his icon set to Game Sprite Mode. When Phong scanned it the system didn't recognize it as Enzo and backed him up simply as Matrix, thinking he was a game sprite. The system still had Enzo's real PID on file and a copy of the child Enzo was created when the city came back online.
