Haki

Spirit Energy

A strange technique that seems to frightened anyone just by looking in their eyes. Shanks and Luffy possess this technique.

Originally seen in the first chapter, Shanks used it against the Lord of the Coast in an attempt to save a young Luffy from the wrath of the sea beast, even at the cost of one of his arms. The Sea King was forced to flee with fear from this power. In Chapter 434, when Shanks went into Whitebeard's ship, he made the crew on Whitebeard's Ship fall to the ground unconcious. When he clashes with Whitebeard's spear to sword, the energy splitted the clouds apart. Later, Luffy unintentionally uses it on Motobaro scaring it away in a fashion oddly similar to Shanks scaring of the Lord of the Coast.
