Power Star

''This article is about the artifact. For information about Professor E. Gadd's invention, see the article'' Power Star (Gaddget).

Power Stars are mystical artifacts with great power. Unlike the regular Stars, which only give limited invincibility, Power Stars grant the user with great strength. In Super Mario 64 and Super Mario 64 DS games, Power Stars are spread throughout the worlds, and Mario (or in the Nintendo DS remake, Mario, Yoshi, Luigi, and Wario) is sent to go find them all. There are 7 power stars (8 in DS remake) to collect in each world, and after finding 70 of them (80 in DS remake), the final boss, Bowser, can be defeated. There are 150 Power Stars in all, as of Super Mario 64 DS, but only 120 were in the original. After a long quest, Mario manages to find all the Power Stars and restore them to Peach's Castle, freeing Peach and the Toads. Stars have since been a recurring theme in Mario, but in particular Power Stars are used often in the Mario Party series of games. As of late, however, they have been phased out in favor of Shine Sprites, however Power Stars may make a return in the upcoming Nintendo Wii game, Super Mario Galaxy.

There are also Silver Stars which aren't as powerful as Power Stars but 5 of them will get you one.
