Runo winced a bit at the crashing sound behind him and glanced back at the furred one a bit apologetically; he really hadn't thought that he could have possibly pushed him that hard, especially being as drained as he was. Even less fortunate was that it seemed that the action had not relayed any message to him in the slightest about waiting before acting. Horrified at Tanikazi's relentless attempt to attack despite the fact that the being in front of them had shown no signs of aggression, he stepped in front of the path of the robotic leg and took the hit in an attempt to keep him from causing damage to the girl that they had just found. 

Even though he had no idea what kind of metal the object was made of, the sickening crack that he felt run through him at the hit was enough to tell him that it was probably built to be much sturdier than he was. Of course, this was only so helpful after collapsing to the floor yet again.
