She Has Bone To Pick With You

I really like Marrow. I think she's one of my favorite obscure X-Men. I'm not going to deny that my initial interest was because I thought she was strangely hot when I was a teen. She really is an interesting character though and has had some good story arcs. You can learn more about her by watching the video below.
