Justice

Justice is a street level Super with powers derived from an injection she's developed herself. Unfortunately, her years of research and the formula for creating this boost serum is stolen when her servers are hacked. She manages to track down the location of the IP used in the hack, and engages 2 thugs. She recognizes one of them as one of the brothers of a crime syndicate she took down years back. In the process, she killed his twin brother and he's now out for revenge. With the stolen formula for the boost serum, both he and his hired muscle are ready to engage whatever Justice can physically dish out. When the two thugs realize she's hanging in the fight, they both boost again, and Justice realizes she is possibly outmatched. The two thugs know no limits in their quest for revenge, and Justice is served with a brutal lesson.
