Mario went to 2.5D in New Super Mario Bros. While Mario and Peach take a walk together through the Mushroom Kingdom, Bowser Jr. kidnaps Peach and flees. Mario gives chase, venturing through eight worlds. Mario eventually catches up, defeating both Bowser and Bowser Jr. and rescuing Peach. In Super Mario Galaxy, Mario is invited by Princess Peach to the centennial Star Festival in the Mushroom Kingdom. Upon arrival, Bowser invades the kingdom and rips Peach's castle from its foundations and lifts it into outer space. After failing to prevent the Princess from being kidnapped, Mario meets star-like creatures called Lumas and their companion, Rosalina. Rosalina tells Mario that Bowser has stolen the Power Stars, the source of power for Rosalina's mobile observatory, and has taken Peach to the center of the universe. Mario then travels to various galaxies to reclaim the Power Stars to restore power to the observatory and reclaim Princess Peach. In New Super Mario Bros. Wii, another 2.5D game, Mario, Luigi, and two Toads are attending Princess Peach's birthday party when Bowser Jr. and the other seven Koopalings ambush the Princess and kidnap her. Mario, Luigi, and the two Toads chase after them across eight worlds, defeating each Koopaling as they progress. The quartet eventually confronts Bowser, defeating him and saving the Princess. In Super Mario Galaxy 2, Bowser, who has transformed himself into a giant using the Power Stars, attacks the Mushroom Kingdom and abducts Peach, taking her to the center of the universe. With the help of the Lumas, Mario pilots Starship Mario, a mobile planet in the shape of his head, in order to travel to various galaxies and gather the Power Stars, used to fuel the ship. After multiple battles against both Bowser and Bowser Jr., Mario eventually arrives at Bowser's lair at the center of the universe, where he defeats him and rescues the Princess. In 2012, Mario returned in New Super Mario Bros. 2 where he collects several coins scattered across the Mushroom Kingdom in addition to saving Princess Peach from the evil clutches of Bowser and the Koopalings.
