Grand Star

A Grand Star is a variation of a Power Star in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. It provides much more power than a regular Power Star. In Super Mario Galaxy, there is just one in each of the Observatories except the last, seeing as they grant access to another Observatory by adding to the power of the Comet Observatory. Each involves a battle with a boss, including Bowser, Bowser Jr., King Kaliente and Megaleg. In Super Mario Galaxy 2, Grand Stars are used to be provided reach for the next world as Bowser tries to get stronger using the Grand Stars for his Galactic Empire and new gigantic size, mannaging to put it into the center of the universe, probably because he uses Grand Stars to make himself huge.
