Sonic Arrows

Sonic Arrows are a gift to some Apollo cabin members from their father, Apollo (The Olympian God of Music and Archery).

Appearance
Though it was never mentioned except in The Last Olympian during the Battle of Manhattan. It seems that the arrows seem to look like normal arrows, save for their supernatural qualities.



Usage
Sonic arrows make a screaming noise as they are shot, and when they land, they unleash a loud blast. Percy describes it as sounding like a power chord on an electric guitar, magnified through the world's largest speakers. They are very useful in battle, because besides killing or maiming enemies, they also confuse them. However, they are not always lethal. They can only kill weaker monsters, other monsters and half-bloods are just stunned.

The Last Olympian
The leader of the Apollo Cabin, Michael Yew, used sonic arrows against Kronos' army on the Williamsburg Bridge in the Battle of Manhattan. Michael then disappeared (presumed dead, he fell off the bridge when Percy struck it with Riptide and released his powers to prevent the Titan army from crossing).
