The Flage (フラージ Furāji) is a Forces of Nature enemy in Kid Icarus: Uprising. It is a ghostly and gelatinous assassin in Viridi’s army that is armed with a sharp blade on each of its hands. It can disappear for a short amount of time, making it a difficult target to hit. While invisible, they can be hit, still make sounds and they also have shadows. The Flage can be considered similar to the Underworld’s own Zuree, due to its similar attack pattern and ability to disappear briefly. Because of this, these monsters are very dangerous and difficult to avoid during aerial battles.
This single-celled organism uses its ability to blend with is surroundings to be an effective assassin. Although invisible, the Flage makes noise and casts a shadow. But it will appear when it strikes, making this the best time to take it out.
Flages appear in the 3DS version as an enemy in the Smash Run.
These gelatinous assassins from the Forces of Nature in Kid Icarus: Uprising can disguise themselves so well, it's like they've disappeared. They furiously slash using their long, bladelike arms and then top off their attack with a powerful finishing blow.
