"Ra's is insane, and dangerous for various reasons." she replied, stopping to watch her mother again. "She works for him, sometimes. Because she is better, she can help protect them, and train warriors. Ra's has tools, an army, the pit...weapons. Shiva doesn't need them." she didn't need any weapon, because she was just that dangerous on her own.
She looked at Terry again, eyebrows raised. "I said a fair right. No tools, no weapons. Shiva would win." If it was just the two of them, nothing but their own fists, she couldn't see Bruce winning. If he had things to work with? Then yes, he could probably do it.
She shrugged, her slender shoulders rising and falling gracefully. "I wouldn't know. I met her shortly after I took up Batgirl." though she would imagine a like growing up with Shiva wouldn't have been much better than the one growing up with Cain. At least he loved her, or thought he did, though she showed it in strange ways. Shiva was about as motherly as a lump of iron.
