Counter (Kid Icarus)
From the Super Mario Wiki
Counter is Palutena's default down special move in Super Smash Bros. for Nintendo 3DS / Wii U. It is based on the power seen in Kid Icarus: Uprising. Like other counter moves, Palutena braces herself for an attack, and when hit, strikes back with her staff, dealing 1.3 times the amount of damage of the attack (dealing a set 10% at minimum). Palutena's Counter deals less knockback than most other counter moves, however, but it can potentially make 1-hit KOs if Palutena blocks any attacks that deal 40% damage or more.
