Wonder how Luffy's awakening will act. Would be lame if they all just turned the floor into an element. Would be cool if Luffy could render all weapons useless as they turn to rubber in his presence.
In terms of Luffy I always look at his power ups in regard to his fight with BB. Gura has that earth tilting move so if Luffy can turn the ground into rubber he can get more leverage. Make it soft landing ground when hit & disrupt normal movements. I also see BB going retarded with his abilities and Luffy might need to have rubber cushion environmental destruction. However, the most beneficial idea would have awakened Luffy take physical damage & rebound it. Think of it like Full Counter from Melodias (Seven Deadly Sins) or how he does bullets. BB gives him a quake to the chest he tanks some of it and hits back with that King Kong and remainder of the quake.
