She is just a more expensive version of Black Cat and that’s it. More of a downgrade in the end. To her credit, she does do an attack that causes Bleeding to all enemies, but you have to wait to upgrade her fully to use it.
She isn’t worth the 90 Command Points it would take to add her to your team. I don’t see any reason to pick her up because she doesn’t have the intangibles that would make her a viable option.
