"An evil being whose strange power may even surpass that of the gods. It is mindless, only possessing the desire to cause disorder and disaster. Long sealed in the Lunar Sanctum, the Chaos Kin is suddenly free to spread anarchy."
Kid Icarus: Uprising - Idol Description (Chaos Kin and Palutena)
"The Chaos Kin binds Palutena to its will, manipulating her form like a foul puppet. By doing so, the Chaos Kin simultaneously shields itself and forces Pit to attack the very goddess he serves."
Kid Icarus: Uprising - Idol Description (Chaos Kin (Ash))
"The Chaos Kin's unfathomable magic allows it to survive even being burned to ash. In this state, only possessing Dark Pit could restore it to its full power. But Pit's selfless rescue banishes the evil creature into the Chaos Vortex."
NA: "This malevolent creature thrives on disorder, living in the Chaos Vortex and feeding on souls—even those of divine beings like Palutena. Its totally unpredictable behavior and appearance make it one of the most dangerous things Pit will face in his adventures."
EU: "A malevolent creature that captures its victims, drags them back to its nest, takes their souls, and uses the empty bodies as puppets. It's not picky about its prey, and even possesses Palutena at one point! Needless to say, the Chaos Kin is one of the most horrible things Pit has to deal with. It might even be in the top three."
