What is the Fenrir Keyblade?

The Fenrir is a weapon from the Kingdom Hearts series of video games. According to Kingdom Heart Wiki, it is a "keychain." This accessory modifies the appearance of one of the game's Keyblade weapons.

The Fenrir can be equipped on the weapon of Sora, the main playable character. When equipped, it gives Sora's Keyblade the look of a key to a pin-tumbler lock.

In Kingdom Hearts II, the Fenrir is given to Sora by Tifa after witnessing the battle with Sephiroth at the Radiant Garden. It can also be found at the Keyblade Graveyard. The name is taken from the name of Cloud's motorcycle in the Final Fantasy VII: Advent Children movie.
