Once again, it is time for the Star Festival and Princess Peach sends Mario a letter:
Would you like to see the stars with me on my balcony? It would be so relaxing to sit back and enjoy the night, because after all, this only happens once in a lifetime (or so they say, I've seen that blue-dressed lady about ten times in the last five years!).
Oh, and I have cake.
With warm regards,
Princess Peach Toadstool
Mario sets off into the night, Toads celebrating and collecting Star Bits. Mario decides to collect some too along the way, to give Princess Peach as a gift. Eventually, Mario reaches the castle and goes inside.
To his horror, he sees Bowser Jr. and the Koopalings holding the Toad Brigade, Luigi, and Princess Peach hostage on the balcony. Jr. tells Mario that he couldn't have done it without his new friend, and as Jr. holds up a new wand, just like the other Koopalings, Mario is shocked to see Young Master Luma inside the wand, pounding and spinning against the glass for help.
Jr. and the Koopalings laugh as they are pulled up to an Airship by Boom Boom, Pom Pom, and none other than Bowser himself. Bowser roars at Mario, saying that he will never save the Princess and the Brigade, not even Luigi. With that, the Airships leave Mushroom World and set off to the center of the universe.
Mario thinks it's all over, and cradles his head in his hands when suddenly a flash of light appears. In front of Mario, who looks up in surprise, is Rosalina, Polari, Lubba, and the Red Luma. The four tell Mario that it is not over, and he can still get Luma, at the very most, for the others are chained up. The Red Luma once again gives Mario the power of the Red Star, stating that this time, its powers will stay with you until you get hurt, not when you touch a Launch Star or water. Mario however, can't spin without Luma, and thus Polari inhabits him, saying, however, that he is old and the spin may not work sometimes, so use it wisely. And thus, Mario sets off, hoping to find the lost Luma.
Mario catches up with the airships and navigates through them, defeating multiple Goombas and Koopa Troopas along the way. Eventually, he reaches Bowser Jr., who tells Mario that the others are already gone, and the Koopalings pass by with the captives. Jr., however, sees Mario make a run for them and challenges him to a battle, which Mario wins. Jr. is stunned long enough for Mario to break his wand, releasing the trapped Luma. Luma thanks Mario and gives him a Red Power Star, which allows Mario to fly again. The two fly away with Polari at their side, while Bowser Jr. yells at them to get back.
The three arrive at the Comet Observatory, which once again is blacked out. The three watch the Power Star go into the Beacon, lighting it with red fire. Rosalina and Lubba arrive, thanking Mario for giving power to the observatory. They tell Mario that the Toad Brigade is being held captive by Larry Koopa, and that galaxy can be accessed by the Terrace, which has just opened up with the Red Power Star's power. Rosalina agrees to rename the Observatory to the Comet Mario and redesigns it, as long as Mario is on the ship. Thus, Mario goes into the Terrace to begin his quest.
After collecting 7 Power Stars, Mario faces Larry Koopa in his "galaxy", named Larry's Lava Lair. Behind him, caged up, is none other than the Toad Brigade. Mario defeats Larry, and the Koopaling reluctantly releases the Brigade and speeds off in a Koopa Clown Car. The Brigade gives Mario a Grand Star and Mario goes back to the Comet Mario with the Toad Brigade.
After beating Wendy O. Koopa on her airship in Sky High Galaxy, Rosalina and Lubba alert Mario that Iggy Koopa that Iggy Koopa is holding Luigi hostage in his castle. Mario goes there and gets him back. Luigi is playable after beating Iggy.
After beating Ludwig von Koopa, Rosalina, Lubba, and Polari tell Mario (or Luigi) that with 80 stars, the Comet Mario can fly to the center of the universe to save Princess Peach. Once the player collects 80 stars, Comet Mario becomes fully functional and speeds off to the center of the universe. Upon entering, the player goes through a painful obstacle course (as before) but it is shorter, and before long faces Bowser and Bowser Jr., who have the Red Grand Star in a strong, Bullet Bill-proof glass ball. In a much smaller, but just as strong glass ball, is Princess Peach.
Bowser and Bowser Jr. fight Mario in a similar manner as Super Mario Sunshine, with Mario having to ground-pound the cracks in the glass balls: three on Peach's, three on the Grand Star's. After this is done, both glass balls explode, and Mario sets out to grab them. However, another figure drops from above and crashes onto the ground below, sending the Red Grand Star and Peach out of sight.
The Koopa, with the colors of Morton Koopa Jr. but the looks of Bowser, tells Mario that he is Morton Koopa Sr. and the ultimate reason behind Jr.'s return, Peach's, the Brigade's, and Luigi's capture, and the events of the entire series. He challenges Mario/Luigi to a fight, and, without waiting for an answer, gravity makes the two fall onto a planet. The entire battle consists of the past two final battles (SMG+SMG2), plus one new one, but with Sr. instead of Bowser. The last part is a 3D version of Bowser's fight in NSMB2, except instead of being inside a castle, this one is in deep space. Sr. breathes silver fire and throws silver sledgehammers, and the player must sneak underneath the Koopa to hit the switch. After that, Sr. falls down out of sight, but thanks to the Koopalings, Jr. and Bowser, Sr. is brought back up, in the exact same size as he was fought in SMG2, and Mario must go up to hit the switch. Sr. and the other Koopas are seen falling down, and as Mario/Luigi watches, he sees that he is above Mushroom World. Suddenly, he falls onto the Gate Planet, where the Red Grand Star, Peach, Rosalina, Lubba, Polari, the Toad Brigade, and Luigi/Mario are waiting. They all thank the plumber for restoring order to the universe, and give him the Red Grand Star. Upon collecting it, everyone gains the ability to fly and they all return to the Mushroom World while the credits roll.

Mario has many different power-ups in this game. A few of them are new, but some old ones that weren't used as much got the glory this time.
The Red Star, which transforms Mario into Flying Mario, is first found in Mushroom World, in the first mission, Luma's Rescue. The power-up has been altered from the first game, allowing you to touch Launch Stars, water, and to keep it until you get hurt, and thus the power-up no longer has a time-limit on it. An example of this is when you reach Jr. (cutscene), and he casts a magical spell at you so you lose the power-up.
Appears in: Grand Finale, Sky High, Falcon Flying, Bob-Omb Blast. TBC...
