Power Star

"Hey, you have 77 Power Stars! How lucky! ♪"

Power Stars are mystical artifacts with great power. Unlike the regular Stars, which only give limited invincibility, Power Stars grant the player great strength, power, and energy.

In Super Mario 64, Super Mario Galaxy, and Super Mario Galaxy 2 when the star for any given level has been collected, playing the level again will turn the Star into a transparent version of itself. This Star can be collected, but it will not add to the player's total Star count. In Super Mario Sunshine, they are replaced by Shine Sprites. In all, there are 754 Power Stars in these four games combined.

Super Mario 64 / Super Mario 64 DS


In Super Mario 64 and Super Mario 64 DS, Power Stars are spread throughout the worlds, and Mario (Yoshi, Luigi, and Wario in the Nintendo DS remake) is sent to go find them all. There are six Power Stars (seven in the DS remake) to collect in each world, and after finding 70 of them (80 in the DS remake), the final boss, Bowser, can be defeated. There are 120 Power Stars in all in Super Mario 64; this was increased to 150, due to Secret Stars, in the DS version. After a long quest, Mario manages to find all the Power Stars and restore them to Peach's Castle, freeing Princess Peach and the Toads.

Super Mario Galaxy
Power Stars make a return in the Wii game Super Mario Galaxy, where there are a total of 121 stars to collect for each Mario and Luigi (for a total of 242).

There are four types of Power Stars: First, there are regular Power Stars, the bread and butter of the 3-D Mario Games. The second kind is the three Green Power Stars that, in addition to acting as normal Power Stars, unlock the Green Launch Star in the Comet Observatory which leads to the Trial Galaxies. The third type is the Red Power Star. There is only one; it appears in the Super Mario Galaxy mission "Gateway's Purple Coins". Last are the seven Grand Stars, the first of which, and the only one obtained without a boss fight, is the first star in Gateway Galaxy. Subsequently, the other six Grand Stars are each collected by beating Bowser or Bowser Jr.. These power up the Comet Observatory and unlock new Domes to explore.

There are also Silver Stars, which aren't as powerful as the regular Power Stars. Five Silver Stars are equal to one Power Star. They can combine to form a Power Star.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Power Stars play the same role as in Super Mario Galaxy. There are 242 Power Stars in total (116 normal Power Stars, six Grand Stars, and 120 Green Stars). If the Cosmic Guide is used, the star will be a Bronze Star instead of a gold one.

Mario Party series
Stars have since been a recurring theme in Mario games, but in particular Power Stars are used often in the Mario Party series of games. They are most often found at a certain spot on the board, waiting for characters to grab them. Traditionally, twenty coins are required to pay for these Stars, but some of the more recent titles in the series feature more unique ways for acquiring these precious items. All of these games allow an option to retrieve Bonus Stars to increase the chances of becoming the Super Star.

Trivia

 * It is interesting to note that, in both Super Mario Galaxy and Super Mario Galaxy 2, the shadows of Power Stars when they hover over the ground are shaped like a circle, while the shadows of Grand Stars are shaped like a Grand Star viewed from the top down.
 * Also in Super Mario Galaxy and Super Mario Galaxy 2, the Power Stars seem to have a rainbow circling around them when there turning around before the character grabs it. This rainbow can also be seen before the player enters the Galaxy, when there selecting which episode, or mission to do.
