Greaser was the eldest of five siblings and grew up in a family where her father, a passionate gearhead, instilled his love for fixing cars in each of his children. From a young age, she excelled in her mechanical abilities. She possessed the remarkable skill of being able to diagnose car issues by sound alone. She could also dismantle engines or transmissions, and reassemble them with ease, often outpacing her siblings.
Today, she is the guardian of the Joe garage, ensuring everything, from dirt bikes and quads to various civilian and military vehicles, remains in peak condition under her expert care.
