Suggested by IKnowledge Beatrix Kiddo is an experienced martial artist who is quite proficient with a blade. She is a solid all around warrior who should be able to give Slade a decent match. That being said, Deathstroke is above a normal human physically thanks to his super human serum. Even without that, I’m inclined to say that he has superior hand to hand expertise. He was able to match up against Batman quite well. While Beatrix Kiddo did learn well, she just won’t be able to compete with this in the end and will have to take the loss. Slade wins.
