She didn't know any of the fighters on the field, but that didn't bother Kelly. Where she hadn't actually been in battle before, she had been training for this at the agency on her homeworld. Like she told Thomas, she knew that she could help, so she was going to.
She made the trip from Providence as soon as she heard that one of the ships had made it down. She hadn't exactly "suited up" for battle, but there was almost an aura of frost surrounding her and emanating around her body as she walked right into the fray. Before any of them got a chance to notice that she was there, she began blasting the group of soldiers with large ice projectiles, killing a few, while mainly subduing most.
Once the enemy soldiers actually took notice of her being a threat against them, they began to turn their attention toward her. "I... did not... go from being tied up in a basement... to this amazing new home..." the rage on her face was apparent when, for the very first time, her body turned into full ice, "just to have it taken away by some assholes like you!" With her final, punctuated words, she took out all of the soldiers who had surrounded her in one blast, with a scream.
After that outburst, she was mostly depleted of her energy, but she was able to turn back into her normal form and continued attacking the soldiers as much as she could, holding on through most of the fight before falling to her knees, catching her breath.
