You are a Yonko that was the Straw Hat crew alliance, the one that can use all types of Haki, which is rare because not all people can even use basic Haki

But you can use all of them

And when you are sitting in a bar of Sabaody Archipelago, waiting for the crew to arrive, a fake Straw Hat crew suddenly comes in

Fake Luffy: "Yo, we are the straw hat crew, respect us-"

They say inside the bar, then you take a look at them which, shuts them up entirely, cuz you are a Yonko, and you can basically kill someone by just looking at them using your Haki
