This is Hack. Or at least her silhouette. Her brother is Slash. Together they are the despicable duo Hack and Slash (hur hur).
Hack, while not extremely intelligent with all things electronic, has fantastic gloves and goggles that help her hack into electronics and bypass security. However, she is quite street-smart and knows just when to strike and where, good at timing and planning and making things up on the fly.
Don’t ever separate her from her brother or there will be hell to pay.
