Kidd wouldhave fought a bit longer if he knew how to use advCoC. Those that lack advCoC coating will be smacked when hit with it. Like Luffy was. When he learnt it, he went toe to toe and ultimately be the victor.
To be honest I wouldn't be that surprised if Kid does indeed get rekt even if I expected him to push Shanks further
It's Shanks first on-screen fight in 25 years, he's going to look amazing.
Only Luffy or Blackbeard can make him look bad
