Killing Edge

The Killing Edge is a recurring weapon in the Fire Emblem series that has a high chance of dealing a critical hit. It appears as an item in Super Smash Bros. Ultimate that can be picked up and, when used, swung forward in front of the fighter. When the sword glows red, it deals double knockback and damage, and if the player successfully lands a hit with it when it is in this state, the critical hit sound effect from the Game Boy Advance Fire Emblem games can be heard.
