Suggested by Destroyer Slur is definitely a pretty tough fighter. After all, she was able to get some good hits in on Bass after all. That being said, anime Bass isn’t quite as OP as the manga version and Slur hasn’t shown that she is ready to deal with cosmic threats. Her hand to hand skills are good, but they simply won’t be fast enough to stop Gemini Saga. His Gold Armor will protect him well and his attacks will still be as devastating as they’ve always been. Gemini Saga wins.
