(Guess I'll post since no one else is)
Sentinel Hawk wasn't about to let this lunatic get to the girl she was defending. She watched the man carefully and had formulated her own plan by the time he had said the word five. He's going to try to use his speed to blitz me and either cripple me or move me out of the way. He doesn't know two things though. He doesn't know I'm covered in Nth Metal and he doesn't know I can regenerate from virtually any physical wound short of bodily destruction. I can't react as fast as he can so if I want to fight what he's about to do, I need to use those two things to my advantage.
She slipped her mace behind her while he stalked and transformed it into a spartan style shield. All she had to do now was figure out his most likely angel of approach. He wants to get to the girl, she's his real target. He won't come at me from behind because it gives the girl too much opportunity to escape. So that leaves...No more time. She acted on instinct and brought the shield to her side just as he took off. She felt the impact long before she ever saw it. He collided with her at speeds that instantly crushed the bones on that side of her body, not to mention liquefying several organs.
The pain was intense, but she pushed through it and reached out with her good arm and grabbed hold of him. The result should be that they both careened away from the girl rather than allowing him to carry himself into her, at least that was her plan. The other part of her plan took full advantage of her Nth Metal clothing as she channeled fifty thousand volts of electricity through her clothing and the Nth Metal shield (for a total of one hundred thousand volts) which should, presumably, move into his body as she turned herself into a giant electrical generator.
Either way she was thrown clear, hopefully with him and hopefully with him at least somewhat disabled. She crashed into the ground but by the time she'd hit the ground her wounds were already healing, her organs stitching back together and her bones repairing themselves. It would take her a few moments to fully recover, leaving her not so much defenseless as limited.
