Why can only Luffy and some few characters can use Emperor's Haki?


Is there any link between being a D and emperor's haki?




**Conqueror's Haki** is _very rare_ ability that **only 1 in a million can
get**. Unlike **Armament** **and Observation** which can be **gained** through
_training_ , Conqueror's Haki **cannot**. You must be **born with it**.

Those with Conqueror's Haki are said to have a **qualities of a King** (or
_Queen_ if female). Which the show has shown with Roger (Pirate King), The
YONKOs (Emperors), Hancock (Empress), and Doflamingo (Celestial Dragon).
