Grandmaster Galaxy

Grandmaster Galaxy is the final galaxy that appears in Super Mario Galaxy 2. The galaxy is located in World S. This galaxy is unlocked when the player gets all 240 stars, just like Grand Finale Galaxy in the first game. It is an obstacle course with puzzles, enemies, and Power Stars at the end. This galaxy contains two Stars: one for completing the level and another one for doing it again but with only one hit point and no checkpoints. In the last case the player gets the star from Rosalina.

Flower Grapple Planet
The first planet is where Mario must use Yoshi to swing on the flower grapples to reach the Launch Star. There are several obstacles along the way, such as Mines and Bullet Bills. Paragoombas also appear, but they are replaced by Choppahs in the second mission.

Flipswitch Planet
After using the Launch Star from the first planet, Mario lands on a planet with Flipswitches, with a backdrop showing moving sprites of items from Super Mario Bros.. The player must touch all 21 Flip Switches (while avoiding Sentry Beams) to reveal the Launch Star.

Electric Maze Planet
After landing, Mario/Luigi finds a Cloud Flower and a fan making an upward gust. Mario/Luigi must use the cloud flower to make it to the Launch Star at the end of the maze. More flowers are supplied along the way.

Platform Planet
A planet that has many platforms that have electric walls moving through them. Also, platforms that shrink and platforms that move when Mario spins appear here too. Octopuses do pop up along the way. Electric force field devices are also found here.

Pull Star Planet
A planet with a lot of electricity. In the beginning, there are some blocks with electricity on them. Later, there is a long segment of Pull Stars where the Mario must avoid the electricity, mines, and Paragoombas to get to the end, where he finds a Launch Star.

Hammer Bro. Planet
This planet is highly infested with Hammer Bros., and Mario has to get past them to reach the other side. Flimps are also present in this area.

The end area has three Boomerang Bros. that Mario must take out. Defeating them reveals a Power Star (or a Launch Star in the Daredevil run).

The Comet Medal for this galaxy is on the far right side of this planet, next to some platforms (as shown on the screenshot).

The Gate Planet
This planet is only accessed during the Daredevil run. It's a small planet with a small house built on it. Mario also meets Rosalina on this planet, which strongly resembles the Gate in its prequel, Super Mario Galaxy. There is also a 1-Up Mushroom behind the house.

Trivia

 * This is the only galaxy in Super Mario Galaxy 2 to not encounter the green stars. This is primarily because the player had to collect all the green stars to unlock this galaxy.
 * This is the only galaxy in Super Mario Galaxy 2 that requires the player to collect Star Bits in addition to collecting the Comet Medal for a Prankster Comet to appear.
 * Using the infinite flutter jump glitch, it is possible to clear the star with Yoshi.
