Dot Matrix (ReBoot)

The daughter of leading Mainframe scientist Welman Matrix, Dot originally was his assistant as a teenager. Now an adult and proprietor of Dot's Diner, Dot also acts as her younger brother Enzo's surrogate parent and guardian since the loss of their father. (What became of their mother is never mentioned in the series.) She later became the command.com of Mainframe in place of Phong.[3] She is admired for her brilliant and invaluable tactical skills, which led to her becoming a workaholic with business interests in most of Mainframe. Although she and Bob took until Season 3 to admit it, they are attracted to one another and this sometimes leads to awkward moments between them. When their father was nullified in the Twin City explosion, Dot and Enzo became each other's only remaining family, and for a long while she was adamant about keeping him from Games.

As Command.Com, she had to fight two successive Viral Wars from a position of inferiority and was forced to make many morally grey decisions, such as having Enzo go into a Game and stay there until he grew into a new Matrix as an insurance policy. It is a sign of her tactical skill that she was able to keep fighting against Megabyte, even with the loss of Enzo and the Principal Office, and then be able to cause some serious damage to Daemon. The emotional stress of the Viral Wars took their toll after the defeat of Daemon, and she fell for Megabyte's plan to impersonate the original Bob out of a desire to get back to the good times and forget all the pain and horror. After this, she came up with a plan that captured Megabyte and his entire Neo-Viral army in one swoop, but this was undone when it was revealed they had only caught a copy of Megabyte and the real virus was inside the War Room. Dot was voiced by Kathleen Barr.

Her name is a reference to the method of using an array of dots to generate characters, symbols and images. The dot matrix was once widely used in the form of dot matrix displays and dot matrix printers. It is possible that her name may also be a hidden reference to a sentient machine with an identical name from the film Spaceballs.
