I don’t think Hammerlock would actually be black, but don’t tell anyone. He is a hunter, but he has (at least in the beginning) naturalist motivations, as he is interested in conservation more than killing. It just so happens that these attempts don’t quite go as planned and these rare creatures just happen end up as trophies on his wall. Later on, the character is depicted more as a hunter, who is interested in learning about these exotic creatures. His method just happens to be to pay someone to kill them.
