What kind of power does the new "Lucy" have?


Are the powers demonstrated by Luffy's replacement as Lucy based on a Devil
Fruit or Haki?

It might be haki because the way he blocked Jesus Burgess' attack, but he
didn't say armament haki, instead used some kind of technique.




He was just using martial arts and haki, many characters fight using haki
without saying it. You can tell he's using haki as his hands turn black.
