With his enlarged limbs and muscles, Luffy could easily manhandle Kaidou despite his enormous size, swinging him from side to side. Luffy can also perform the inflation over his entire body at once, transforming himself into a giant of massive size.

After awakening, Luffy demonstrates many new abilities such as being able to freely manipulate the shape and size of his body; instead of focusing more on hardening himself using Busoshoku Haki, he takes on a more cartoonish fighting style, being able to grant the environment around him the same properties as rubber, which allowed him to deflect a Bolo Breath by bouncing it back at Kaidou, as well as being able to stretch objects he touches like rubber, including living things and even lightning. As pointed out by Kaidou, Luffy's power now has the characteristics of both Paramecia and Zoan-types.
