Mackey is a whiz kid with computers and technology. He has to constantly make repairs to Priss' bike because of her driving and the situations she gets into. Mackey is also the sole caretaker of the hardsuits. He can pilot an armored suit himself, and drives a large truck that delivers the Knight Sabers and their bikes to a situation. Mackey's character was also extremely perverted, watching the Knight Sabers (even his own sister) in the nude as much as he could. (Source: Wikipedia)
