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

The Grandmaster Galaxy is the final galaxy of Super Mario Galaxy 2. It is located in World S. This galaxy is unlocked when the player has collected all 240 Stars, much like the Grand Finale Galaxy from Super Mario Galaxy. This galaxy contains two Power Stars: one for completing the level and another one for a second completion, this time 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, mainly because the player has to get all Green Stars in order to unlock this galaxy.

The first area is where Mario must use Yoshi to swing on the flower grapples to reach the Launch Star at the end of the area. 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 spoken to.

After using the Launch Star from the first planet, Mario lands on a planet with Flipswitch Panels, with a backdrop showing moving sprites of items from Super Mario Bros.. The player must activate all 21 Flipswitch Panels, 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 maneuver to the Launch Star at the end of the area. More Cloud Flowers are subsequently supplied along the way. There is also a 1-Up Mushroom at the top left that can be reached using the Cloud Flower.

This area contains planets that are made up of Shrinking Tiles and Red-Blue Panels. Octopi appear along the way. Sentry Beams are also found in the area. Mario must avoid all obstacles in order to successfully reach the Launch Star at the end of the section.

An area with a noticeable amount of electricity. In the beginning, there are some electrified blocks, later being followed by a long segment of Pull Stars where Mario must avoid electrical currents, mines, and Paragoombas to reach the end, where a Launch Star is located.

This planet has a noticeable amount of Hammer Bros., and Mario has to either evade or defeat them to reach the other side. Flomps are also present in this area.

The ending platform has three Boomerang Bros. that Mario must defeat. Defeating them reveals a Power Star (or a Launch Star in the Daredevil run). Note that defeating the Hammer Bros is not necessary for getting the Power/Launch Star to appear.

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. The planet is 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. Mario will still lose a life if he falls off, and will have to redo the level if this happens.

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 that the leader is seen sleeping. Yellow Toad is also asleep, and if the player speaks to him, he will mumble about 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 collects the galaxy's Comet Medal and deposits 9,999 Star Bits to the Banktoad.

The player must redo the The Ultimate Test mission, but under Daredevil Comet conditions. There aren't any Checkpoint Flags in this mission and, in the first area, the Paragoombas have been replaced with Choppahs and more mines have been added. Additionally, after defeating the Boomerang Bros. at the end of the level, rather than the Power Star appearing, a Launch Star appears that takes the player to the Gate-like planet where the Power Star and Rosalina are located.

Music from the original Super Mario Galaxy is played throughout the level, including the themes of Gusty Garden Galaxy, Good Egg Galaxy, Bowser's Galaxy Reactor, and Comet Observatory.

Trivia

 * This is the only galaxy in Super Mario Galaxy 2 which does not have any Green Stars.
 * 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.
 * The three figures from the Shiverburn Galaxy can be seen in the Pull Star Area.
 * If the player collects all Stars (e.g. completing all galaxies except Grandmaster) and then completes this galaxy, a special message will appear on his or her Wii Message Board, both congratulating and thanking the player for completing the game 100%.
