Music when Luffy first used haki against Fujitora? In the Dressrosa arc there is a scene where Luffy is carrying Law and Fujitora steps in front of him. 

Luffy then drops him, coats his right arm and takes a stance. During this scene there is a track that plays but I can't seem to find it anywhere. 

I'll be back later to add the following information:


Episode name and number
Youtube clip of the scene I am referring to


But if anyone knows off hand, please let me know? I'd like to find an OST version of it but I can't seem to locate the track name. 

It's episode 683 
With a Rumbling of the Ground - The God of Destruction, Giant Pica Descends
Here is the youtube clip

I have pasted the website that allowed me to find this OST below, it could be useful to use in the future:
