Ripper

Ripper barely made it to the superhero scene. For starters, she had powers that made it hard to be a hero - she regenerated and her bones were really strong. That's not too bad. But, she can also pull simple objects out of her skin made of bone. She didn't advertise that, really. In her one and only combat, she was just a heroine using a bone sword that was strong and sharp enough to cut through alien armor. But, her time as a hero wasn't meant to last. In the battle, she was thrown through the portal that the aliens arrived through - and now she's trapped on the other side. On a world that Arc Knight says was doomed.
