Galaxia Darkness is Meta Knight's Final Smash in the Super Smash Bros. series. Meta Knight enlarges his cape and throws it over an unlucky player causing the whole screen to go dark. Then, you see large slashes and all of the players goes flying, usually to their doom. If Meta Knight misses someone while using Galaxia Darkness, nothing will happen.
This final smash is relatively easy to perform. Simply swing the attack in front of the player and any player caught by the attack get a large knockback attack dealing about 40%. The remaining players get hit with a smaller attack dealing 10% and small knockback.. In Brawl, the move also hits the players right behind Meta Knight.

Meta Knight's Final Smash. He flips his cape, and the darkness within envelops his foes and plunges the world into shadow. He then unleashes a series of sword strikes that do terrible damage and launch his foes. In the darkness, Meta Knight can also reach and attack distant enemies. One can imagine Meta Knight zipping back and forth at high speed to accomplish this.
