Gold Star

The Gold Star is the third of the Crystal Stars Mario collects in Paper Mario: The Thousand-Year Door. Prior to the events of the game, the ringmaster of the Glitz Pit, Grubba, used the Gold Star to power a machine that lets him suck out the life force of the fighters to power up his own. Upon entering the Glitz Pit, Mario and his partners witness a fight between The Koopinator and Rawk Hawk, which the latter wins and receives a belt with the Gold Star on it. With their objective in sight, Mario and his friends climb up the ranks of the Glitz Pit, only to find that the Gold Star on Rawk Hawk's belt is fake. After claiming the champion title themselves, Mario discovers that Grubba has the Gold Star and confronts him in battle, where he fights in a powered-up form known as Macho Grubba. After being defeated, Grubba's assistant, Jolene gives Mario the real Gold Star as thanks. The Gold Star teaches Mario the move Power Lift to use in battles.

The fake Gold Star appears later in one of Bowser's intermissions, where he discovers Rawk Hawk's secret training facility. Confusing the fake with the real thing, he attempts to steal it, but Rawk Hawk shows up to stop him. As Bowser fights him off, Kammy Koopa is knocked into the fake Gold Star, which breaks it, and Rawk Hawk tells Bowser who has the real one, calling Mario by his stage name "Gonzales".

Trivia

 * The Gold Star is the only Crystal Star not to be named after a jewel. Gold is a mineral or element.
 * While Grubba has the Gold Star in his possession, he can use it to power up himself, much like Mario uses Power Lift to boost himself up.
 * The Gold Star and the Diamond Star are the only Crystal Stars that are not from a chapter that involves the X-Nauts or the Shadow Sirens in any way.
