I took a look through some of the frames of that scene, and it looked as if Ruby absorbed energy from the last Beowolf. When she killed all of the others, they didn't show any sign of energy coming out of them. I also figured that there might have been a figure appearing in the red shape from the blast. To me, it looks like a woman lying down; you can see the feet on the left and her head and hair on the right. I can't say for sure that that was intensional with it being rendered in a 3D space and all.
