Exposed to the street life at a young age, Matilda Baruda would eventually adopt that lifestyle when she got older. She would be in and out of trouble with the law, often causing property damage and getting into fights. She would eventually become an independent B.W., going under the street moniker of Grilla, but eventually became a member of the Mad Mox Crew. Grilla is a rough, tomboyish, street smart thug with a bad temper. Her boorish nature is accompanied by a ruthless and vicious aggression, making her dangerous. However, Grilla does have a softer and, somewhat, maternal side to her. Though she may not act as such, she cares for her companions and will come to their aid if needed.
