Super Luigi Galaxy Part 3 - Kitchen World Galaxy

The centennial Star Festival is held to watch a comet in the Mushroom Kingdom. On the night of the Star Festival, Princess Peach discovers a star-shaped creature called a Luma and invites Luigi to come to the festival to see the Luma she discovered. Just as Luigi arrives at the town, Bowser invades the Mushroom Kingdom in a fleet of airships, littering the landscape with fireballs and petrifying its citizens in crystals. He invites Peach to his creation of his galaxy and removes Peach's castle from its foundations using a giant flying saucer, and lifts it into outer space. Kamek, one of Bowser's minions, launches Luigi, who tried to rescue Princess Peach, into space and he eventually lands on a small planet from Kamek's magic while the Luma escapes from Peach's hands. On the planet, Luigi wakes up after being knocked unconscious and meets the Luma that Peach found earlier, along with the space Rosalina and her star-shaped companions, the Lumas. Rosalina describes herself as a watcher of the stars who uses the Comet Observatory to travel across the universe. However, Bowser has stolen all of the Power Stars that act as the Observatory's power source, rendering it immobile. Bestowed with the power to travel through space through one of the Lumas, Luigi sets off on a journey across the universe to reclaim the Power Stars and restore power to Rosalina's observatory. Along the way, he finds friends from the Mushroom Kingdom such as Luigi and the Toads while fighting Bowser and Bowser Jr. at certain points. Upon collecting enough Power Stars, the Comet Observatory flies to the center of the universe, where Bowser is holding Peach captive. While confronting Bowser, Mario learns that he plans to rule the entire universe with Peach at his side. Luigi defeats Bowser and frees Peach, but one of the galaxy's planets collapses on itself, becoming a supermassive black hole that begins consuming the entire universe. The Lumas sacrifice themselves and jump into the black hole to destroy it, causing the black hole to collapse into a singularity and the universe is recreated entirely as the singularity explodes in a huge supernova. Rosalina appears to Luigi, revealing that dying stars are later reborn as new stars. When the universe is recreated, Luigi awakens in the Mushroom Kingdom, which was recreated in the supernova, alongside Peach and Bowser, and he celebrates the new galaxy that has emerged in the skies. If the player collects 120 stars, Rosalina will thank the player and, with the reborn Lumas, leave aboard the Comet Observatory to travel the cosmos again.
