Fierce Deity (Legend of Zelda: Majora’s Mask)
Whilst not strictly a sword the Fierce Deity is a mask which Link can wear that transforms him and bestows upon him special powers and a glorious sword. It consists of two blades that criss cross to form one. Is it functionable? Maybe. Is it awesome? Fuck yes!
The Fierce Deity is one of the transformations Link turns into in Majora’s Mask, achieved by wearing the Fierce Deity’s Mask. This transforms him into a mysterious and powerful warrior resembling a Hylian. It is one of four mask transformations in the game.
Whilst the weapon straddles that line of fact and fantasy there is no argument that it is a work of art. Deadly art, but art none the less. No elves or magical dwarves went into the making of this blade but does that make it any less exceptional? No, it doesn’t.
