Grandmaster Galaxy

"Mario...so you were the one who collected all of the scattered stars...I want to thank you...your deeds will live on in the memory of the cosmos..."

- Rosalina

Grandmaster Galaxy is the final galaxy that appears in Super Mario Galaxy 2. The galaxy is located in World S. It is the most difficult galaxy in the game. This galaxy is unlocked when the player gets all 240 Stars, like with the Grand Finale Galaxy in the first game. It is an obstacle course with puzzles and enemies. This galaxy contains two Stars: one for completing the level and another one for doing it again under Daredevil Comet conditions. In the latter case, the player gets the Star from Rosalina. Unlike the rest of the galaxies, Green Stars don't appear here. This is primarily because the player had to collect all the green stars to unlock the galaxy.

The first area 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 in the first mission; they are replaced by Choppahs in the second mission. A Toad can also be found on this planet who will shout Yoshi's name when talked to.

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 Flipswitches (while avoiding Sentry Beams) to reveal the Launch Star.

After landing, Mario finds a Cloud Flower and a fan producing an upward gust. Mario must use the Cloud Flower to make it to the Launch Star at the end of the maze. More Cloud Flowers are subsequently supplied along the way. There is also a 1-Up Mushroom at the top left here that can be reached with clouds.

This area contains planets that are made up of many platforms that have electric walls moving through them. Also, Shrinking Tiles and Flip-Swap Platforms appear here too. Octopuses do pop up along the way. Sentry Beams are also found here. Mario must avoid all obstacles in order to successfully reach the Launch Star at the end of the section.

An area 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 Mario must avoid the electricity, mines, and Paragoombas to get to the end, where he finds a Launch Star. The 3 figures from Shiverburn Galaxy appear here.

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

The ending platform 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 these planets, next to some platforms (as shown on the screenshot). In the Daredevil run, the Comet Medal is replaced with a 1-Up Mushroom.

This planet is only accessed during The Perfect Run. It's a small planet with a small house built on it. Mario meets Rosalina on this planet, which strongly resembles the Gate in Super Mario Galaxy. There is also a 1-Up Mushroom behind the house and next to Rosalina is the final Power Star of the game, which Mario needs to collect.

The Ultimate Test
This mission is unlocked once the player gets a total of 240 Stars. The player must complete all the various tasks mentioned above. There are checkpoint flags at the beginning of the Electric Maze Area, the Platform Planets, and the Pull Star Area. Throughout the mission, the player can also speak with the Toad Brigade members. This mission, along with the Daredevil Run, is the only time the leader is seen sleeping. Yellow Toad is also asleep, and if the player speaks to him, he will say Star Bits, giving the player a hint on how to unlock the final mission.

The Perfect Run
The Prankster Comet for this galaxy is unlocked when the player finds this galaxy's Comet Medal and deposits 9,999 Star Bits to Banktoad.

The player must redo the The Ultimate Test mission, but under Daredevil Comet conditions. There are no Checkpoint Flags whatsoever, the Paragoombas of the first planet are now replaced with Choppahs, and there are considerably more mines than before.

If Mario avoids all the obstacles, he'll run into Rosalina, who will thank the player and award him with the final Power Star.

Music from the original Super Mario Galaxy is played as well. The music that is played in order is Gusty Garden Galaxy, Good Egg Galaxy, Bowser's Galaxy Reactor, and Comet Observatory.

Trivia

 * 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.
 * If the player looks back in first person mode at the starting point of the Pull Star Area, the Launch Star from the previous area can be seen above the Gate planet in the Daredevil Run.
