A Power-Up Drop is an item debuting in Kid Icarus: Uprising, usually appearing in aerial segments and dropped by Treasurefish. When collected, they temporarily give Pit invincibility to enemy attacks. After about a minute, the Power-Up Drop will wear off. The Power-Up Drop itself is a golden droplet that flashes between yellow and blue colors with wings and a halo. Like with most other items, it is a two-dimensional sprite.
"Power-Up Drops make you invincible against attacks. While its effects aren't long-lived, this powerful item can turn the tide of a losing battle if used wisely."
