To me Katakuri was an enemy that make Luffy growns up in some many aspects not only with his observation haki, he force Luffy to use the snake man and that form of the Gear Four it's another level and he have what we can say a similar devil fruit so make my hype it's even bigger to one day see the awaking of the gomu gomu no mi, Katakuri to me it's not only a amazing villain but also a incredible and honorable warrior. Excellent choose dude
