The Triforce, as seen in "Zelda Game".
The Triforce is a golden relic from the land of Hyrule, famous for its wish-granting powers. There are three pieces: the triforces of Power, Wisdom, and Courage. Link owns the triforce of Courage. ("Zelda Game")
Balzak Globotron briefly encountered the Triforce in a laboratory on a Flying Saucer Aliens ship. He didn't pay it much attention, though. ("Balzak Globotron")
Figs knew that if they ever were to achieve the Triforce, they most certainly would not deserve it and should escape it at all costs. ("A Fig's (useless) Life")
