There is a form of haki no one in one piece has mastered and only joyboy was able to do it. The haki is advanced imperial haki. The haki will send out yellow/gold lightning that would be so bright it will light up the whole world.
When luffy finally uses this haki it will make every single person even the likes of akainu bow down to luffy. This haki is also the source that vegapunk needed to activate the ancient giant technology.
