Bellamy probably the first one to get eliminated. Cavendish might take this tbh. His speed and swordsmenship in his Hakuba form is kind of crazy. Unless Pedro pulls out the Sulong. Jabra could also be the contender here with his Wolf Zoan and Rokushiki.
Cavendish should be able to just tap into Hakuba, since he seems to be supressing him at all times. On the other hand Pedro needs full moon, but I can definetly see Sulong Pedro able to contest with Hakuba. If not outright win. Cuz Pedro was already impressive without his Sulong. Unfortunately we never saw his Sulong form.
