Hello,

Could somebody help me identify a character who appeared in the first comics I've ever read?

Unfortunately, I don't have any picture of said characters (lost the comics decades ago)

It was a black woman dressed as a cat or a panther. The source of her powers was magik, so she was able to make Superman bleed with her claws.
If I recall correctly, she was fighting illegal fur dealers.

Also I'm not sure about this last part, but I believe the story had some Superdickery as Superman let escaped tigers bite him, breaking their teeth on his skin.
