Hakuneko is originally a white lioness but due to a genetic arrangement of the splicing process she's transformed into a bai ze/Hakutaku-like creature. Other than the horns and additional eyes, her skeleton has been transformed to lead also.
As for superpowers; she can manipulate metal. However, she limited to lead manipulation as a defense mechanism to lead poisoning coming from her bones. She can form lead weaponry (or even deflect bullets) and clones as a general form of offense. Or even coat her body in lead to resist radiation.
She also can manipulate and regenerate her own bones, therefore giving her extra lead ammunition to her arsenal. With regeneration comes self healing capabilties too.
Her suit is an anti-grav outfit to reduce the weight of her own skeleton so that she can be more agile on her feet. It also allows her limited flight capabilities.
