Under any other circumstance, Shauna would punch anyone that ordered her to do anything. She was her own person, and she did only what she wanted to do. So, while Roma's 'order' made her pause, she was ultimately fine with it solely because he kept his word. He said if she joined him, she'd never run out of people to punch, and he was right. Eyes locking onto the group of marines, Shauna rushed them head on. 

She struck fast and hard - harder than most people would expect and with skill that defied her age. Lashing out, Shauna's fist collided with a kneecap and a marine buckled to the ground. Jumping forward, her knee thrust outward and the nose of a marine was broken. Landing, she swung wildly while the marine staggered back, his fist meeting his ribs with enough force to send the man barrel into 2 others. Whipping around, the back of her hand collided with a face and she swung around, burying her left fist in the marine's stomach.

She was breathing heavily, the blood loss from the cuts starting to get to her. Her head was swimming, but she kept fighting. The back of her heel collided with a face while her fist was buried in another. Wrapping her arms around the waist of a marine, she hugged him from behind before pulling back, her back bending as she suplexed the man, his head head hitting the ground while causing his neck to twist at an awkward angle. Grabbing his face, Shauna roared as she threw the marine into another group, knocking them all down like bowling pins. 

Looking around, she breathed heavily while holding her face, looking back to the ship. Her eyes struggling to focus on the people, though she could make a few things out and her brain was still functioning... Somehow. 

"Hey, cap'n," Shauna called out to Roma, "you want me to deal with fish sticks?" She inquired, cocking her head to the side.
