Flage

The Flage (フラージ Furāji) is a Forces of Nature enemy that debuted in Kid Icarus: Uprising.

Physical Appearance
The Flage is a long, gelatinous green mass with dark spots scattered across its body. It possesses the Forces of Nature's signature cycloptic yellow eye, as well as two blade-like arms.

Kid Icarus: Uprising
The Flage will blend into its surroundings and reveal itself at random, slashing at its opponent once within range. Though its invisibility is more impressive than the Zuree, its camouflage is flawed by the presence of its shadow and the noises it emits.

Super Smash Bros. for 3DS/Wii U
Flages appear as enemies in the multiplayer feature Smash Run. Defeating them grants the player power-ups.

Flage
''This single-celled organism uses its ability to blend with its 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.''

''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.''

Trivia

 * Its Japanese and English names are derived from the word "camouflage."
