Pit calls to the goddess Palutena for her army of Centurions. An enormous image of Palutena will appear in the sky (which is transparent on most stages, but is easier seen on stages such as Final Destination). The Centurions fly onto screen one-by-one, ramming into other players at incredibly high speeds. When hit by a Centurion, the opponent takes a range of 15-25%. Each Centurion deals a single attack to a character, and then falls in battle. During the course of the attack, Pit is free to move and attack as he pleases, but he is not invincible during his Final Smash. Centurions can be destroyed by enemy attacks; however, due to Centurions' high damage output and speed, it is far more preferable to dodge.
The quote Pit yells out is: "All troops.....move out!" ("全軍.....突撃!", All troops/units.....charge!)
In Super Smash Bros. 4, Pit's Final Smash changed from Palutena's Army to Three Sacred Treasures. However, it is referenced in Palutena's Guidance, where Palutena, now joining the fight and becoming a playable character, refuses to help Pit during their battle.
In the original Kid Icarus for the Nintendo Entertainment System, the Centurions played a large role in boss fortresses. On those particular levels, Pit could find hammers and use them to break open statues scattered around the area, freeing the Centurion trapped inside. When Pit eventually reaches the boss chamber, any Centurions that he rescued will fly in and attack the enemy. However, this only effectively damaged Twinbellows; Hewdraw was too hard to hit and Pandora beat them with ease. This is where the Palutena's Army attack concept is taken from. Just as in Brawl, the Centurions in Kid Icarus would perish after being hit a single time, though they could attack repeatedly in the original game. They did not return for the sequel; Centurion statues are present, but they only hold items now.
