Very tough fight. People say Kimimaro took on Lee, Gaara and Naruto while half dead so should pwn Haku, but Haku's bloodline limit ability (mirror thing) is virtually undefeatable. We havent witnessed Kimimaro being intelligent, so unlike maybe Itachi, who can figure out a weakness in almsot any jutsu, I dont think Kimimaro can get out of it. The fight could potentially be over very quickly, if Haku goes for the mirrors quickly, or if Kimimaro gets a few hit in early on. Tough fight. Good fight. All depends on who makes the first move.
