Bowser's Galaxy Generator

"All right! Time for the grand finale, Captain! Somewhere in there... Your princess is waiting! You need to stop that monster before he devours everything in his path! Get in there and show him what ya got!"

- Lubba Bowser's Galaxy Generator is a galaxy in the game Super Mario Galaxy 2. It is located in World 6 and is the last galaxy of this world. Bowser is fought here for the final time. The entire galaxy appears to take place inside a giant, foggy hallway; this is likely somewhere inside the giant Bowser head that forms the galaxy's exterior.

The galaxy uses elements from every part of the game, such as Snake Blocks and the Drill Spin. Yoshi will also be needed to bypass certain obstacles, but he cannot be used in the final battle (without the use of glitches).

The power-ups found here are the Cloud Flower, Blimp Fruit, Spin Drill, and Dash Pepper. The galaxy has many obstacles such as lava and electricity. Common enemies here include Magikoopas, Banzai Bills, Hammer Bros., Boomerang Bros., and Magmaarghs.

The Prankster Comet for this galaxy is the Speedy Comet. This Speedy Comet requires the player to reach the Star before time expires. There are + Clocks that will increase the player's time limit, and Bowser is not present.

Planets/Areas
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
A small planet that resembles the platforms in the Bowser levels of the first game. Once Mario lands on this planet, a Luma leads Mario down a path and change into a Launch Star. However, if Mario chooses another route and climbs to the top of a pole, he obtains a Life Mushroom. Note that the Large Door Planet is almost directly under the planet a long way down.

Platform Planet
A small platform occupied by three Hammer Bros. The player must defeat them to reveal the Floaty Fluff to sail down the Volcanic Planet, although it is not actually needed to get down safely since the player can touch a wall of lava and use this momentum to fall to the bottom safely. During the speed run, the Hammer Bros. are replaced by two Boomerang Bros. The Platform Planet is actually separate from the Volcanic Planet.

Volcanic Planet
A planet made out of lava waterfalls that come out of volcanoes. Fireballs come out of torches, and Mario can fly using the Floaty Fluff found in the previous planet until he reaches the bottom or he can touch a wall of lava and use this momentum to fall to the bottom safely and avoid the fireballs until he gets to the bottom, where he can use a Spin Drill to exit the planet.

Banzai Bill Planet
A cylindrical planet surrounded by lava. There are several Banzai Bill Cannons here, and Mario can use the Spin Drill to go through the dirt and access other areas of the planet while avoiding the many Banzai Bills and lava; however, he can save much more time if he ditches the spin drill and backflips on to the Banzai Bill Cannon then long jumps to the Launch Star at the end. Also, during the Prankster Comet mission, the Banzai Bills are replaced by Octoombas.

Lava Castle Planet
In this sidescroller planet are several platforms that spin around, Bullet Bills and also Cloud Flowers. There is lava at the top and bottom of the planet. At the end is a Launch Star. There is a glitch that allows the player to infinitely circle this planet which is shown below. During the prankster comet mission, the Bullet Bills are not present. Also, on the top of the planet, there will be a small area barely tall enough for Mario and Luigi. The area is filled with coins and a 1-Up Mushroom and leads to the Luma that turns into the Launch Star. This can be a shortcut.

Yoshi Bridge Planet
A planet with a wooden bridge where a Magikoopa is found. There is also a platform that tilts according to Mario's current position on it. Yoshi's Egg is found on the right side, and the Yoshi can use the flower grapples on the left side to reach the next planet.

Yoshi Magma Planet
A big, long planet. If Yoshi goes forward and swings to the left, he will get a 1-Up mushroom. From the platform with the Boomerang Bro on it Yoshi can infinitely flutter-jump until he is so high he gets caught in the Lava Castle Planet's gravity orbit, Mario (with or without Yoshi) will orbit the planet indefinitely. Yoshi must navigate the sinking lava platforms to reach the left side. On the left side are three Boomerang Bros. and several Lava Geysers. After defeating the enemies, two lava walls open briefly. After eating a Dash Pepper, Yoshi can rush through a long section before the walls close again and crush them. After using a Sling Star, Mario and Yoshi get to a second area with a large chain of Snake Blocks. They must dodge the lava geysers and Magmaarghs. At the end, there is a Comet Medal and a Blimp Fruit that is used to avoid being eaten by a Magmaargh. The player needs to use Yoshi in order to obtain the Comet Medal. The top of this planet can be explored by getting Yoshi on the previous planet and using the infinite Flutter Jump glitch. From up there, the Large Door Planet can be seen, but the Big Door itself cannot.

Large Door Planet
A castle-like planet with a few Lumas, a large Bowser Statue, and a pole that Mario can use to get to the top. Mario must get off of Yoshi to climb the pole unless he uses Yoshi's Infinite Flutter glitch. On the top part of the planet, there is a Life Mushroom on the left, on top of another pole and meteorites in the center. Mario must Ground Pound these to smash open the door locks and finally enter Bowser's lair.

Throne Planets
A small planet shaped slightly like a star. In front of this planet is another planet that is shaped like a large throne. Bowser is seen sitting on this throne when Mario first enters the area. He only remains here briefly before battling Bowser on the Bowser Battle Planet.

Bowser Battle Planet
It is identical to the other battle planets. It is a small, round planet made out of black bricks with a few rocks that release coins.

Bowser Battle Vortex
This area is the setting of the second stage of the fight with Bowser. It is a vortex with a black hole in the background. The only places for Mario to stand is on the meteorites used against Bowser. If all present meteorites have been used up or destroyed, a new one will immediately be called in; the meteorites will never disintegrate on their own.

Garden Planet
A small garden planet with flowers, a little pond, and dirt. There are some Star Bits on the bottom of the planet. This is the planet where the final Grand Star and Princess Peach will appear after defeating Giant Bowser. It resembles a simplified version of Gusty Garden Galaxy's planets since there are grass and flowers on the top half and just dirt on the bottom.

Green Star 2
The second Green Star is in front of the tilting platform, where Yoshi is. The player can see the star far out, and there are multiple ways to reach it. The easiest way is to get on Yoshi, jump straight toward the star from the tilting platform, flutter jump, dismount, and spin to get the star. Another way is that Mario can also reach the star if they have the Cloud Flower power-up, where they must long jump, make a cloud, and then long jump again. Yet another way is to beat the Boomerang Bros. on the next planet, get the Dash Pepper in the opening, and go back to where the Green Star is. Dash Yoshi can then jump, flutter jump, and dismount to get the star.

Prima Official Game Guide description

 * "This is it -- Bowser's last stand in the cosmos. If you can survive his trap-loaded defenses and Magmaargh minions, Bowser will challenge you to a final showdown for the sixth Grand Star. Bowser will not go quietly, though. You must muster all your strength to bring down the Koopa King and free the universe from his evil plans."

Trivia

 * When Yoshi is dismounted right before the fight with Bowser, he waves goodbye to Mario or Luigi.
 * A remix of Bowser's Galaxy Generator's music can be heard in Mario & Sonic at the Sochi 2014 Olympic Winter Games.
 * Both Bowser's Galaxy Generator's music and the final boss theme, "Fated Battle", appear as selectable songs in the Mario Galaxy stage in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate.
 * This is the only galaxy in a game where the galaxy's world map icon is seen in a cutscene, and the only Bowser galaxy whose icon is not a castle on a lake of lava.
