Pandora's Box

Pandora's Box (パンドーラの箱 Pandōra no Hako, "Pandora's Box") is a Treasure Box variant that debuted in Kid Icarus: Uprising. Appearing in Solo Mode, Pandora's Box inflicts damage to everything within its radius, and occasionally drops loot in the wake of its attack.

Pandora's Box
''Pandora's Box is in many ways the exact opposite of a Treasure Box. More often than not, these boxes are rigged with traps. But once in a while, they'll contain a pleasant surprise. If your health is low, it might be better to avoid them.''

Trivia

 * Pandora's Box is loosely based on the Greek mythological artifact of the same name.
