Killing Edge

The Killing Edge is a recurring weapon in the Fire Emblem franchise 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 Killing Edge glows red, it deals double knockback and damage, and if its user successfully lands a hit with the Killing Edge in this state, the critical hit sound effect from the Game Boy Advance Fire Emblem games can be heard.
