Triforce
The Triforce is a sacred item that appears throughout The Legend of Zelda. It is split into three different parts: the Triforce of Courage (associated with Link), the Triforce of Wisdom (associated with Zelda), and the Triforce of Power (associated with Ganondorf). The Triforce does not distinguish between "good" and "evil," and when the three pieces of the Triforce are reunited, it can grant whatever wish the holder desires. In the Zelda series, Ganon seeks the Triforce in order to gain power and take over Hyrule while Link and Zelda attempt to stop him.
In the Super Smash Bros. series
The Triforce appears as the symbol of the Legend of Zelda series in all 4 Smash Bros. games. In Super Smash Bros. Melee, on Zelda and Sheik's Target Test stages, it appears as structures. It also appears in the Underground Maze of Melee's Adventure Mode as a goal one must reach to complete the stage. In Super Smash Bros. Brawl and Super Smash Bros. 4, the Triforce is seen in Link's and Toon Link's Final Smash, Triforce Slash, as it traps the opponent while Link or Toon Link slashes them.
