Palutena's Arrow is Pit's Standard Special Move. Pit will pull his bow string back, and fire it when the the button is released. The arrow does 5% uncharged and 11% charged. Pit's arrows move much more quickly than other character's arrows, and can be controlled in midair. He is not able to hold his drawn bow indefinitely, however; he will release the arrow eventually, unlike Link and Toon Link.
Palutena's Arrows can actually be curved around in a full circle if controlled properly and avoid going off screen. Also, if two of Palutena's Arrows collide, they will cancel each other out.
This is one of the few Special moves that can perform a 180˚ and 360˚ reversal, by holding the opposite direction you're facing while charging an arrow. This does not affect attack power.
Palutena's Bow is exclusive to Brawl and never appeared in Kid Icarus, nor its sequel. But Pit used a bow as his main weapon in his games. The move appears to be based on the Arrow of Light, one of the three Sacred Treasures used to defeat Medusa. Normally, Pit fired regular arrows.
The Bow of Light, also known as the Sacred Bow of Palutena is Pit's weapon of choice. The bow splits into two blades, which Pit can wield. In the Kid Icarus series, Pit's bow did not have the ability to split into two blades. This is explained in the Subspace Emissary.
The bow Pit got from Palutena after the Medusa incident. As a standard bow, it's capable of firing arrows of light that can change direction. It can also be split to form two short swords--Pit holds one sword in his right hand in a standard grip and one in his left in a reverse grip. He may hold them like this so he can shift between bow and swords without losing a beat.
- The arrows look like a bright version the arrows fired from the Dark Cannons.
