Storyline

As Bowser’s airship arrives at the Mushroom Kingdom, everyone quickly hides in the castle’s secret treasure room. Unable to find anybody, Bowser leaves angrily and heads back to his kingdom. Back at his castle, he is chatting with Topper and Ludwig, the leaders of the Broodals and Koopalings. “What will I do now that Peach and Mario know how to avoid my attacks?” he asks.

Ludwig comes up with an idea. “If you take over the universe, they’ll have no choice but to obey you.”

”How have I never though of that?” Bowser wonders. He gets inside of his rocket and begins to fly into space to find a way to take over the world. To make sure nobody can stop him, he scatters his minions around the planet.

After seeing all of these falling objects, Mario decides to venture back to the Cap Kingdom to reunite with Cappy and save the world.

After the final Bowser showdown in the Galactic Kingdom, Mario realizes something. Bowser was defeated, but something is still after him. Once the player reaches 400 moons, they can sail for the Intergalactic Kingdom, where they meet Mrs. Zorgrogorf and her three alien children. She has been the real mastermind behind taking over the world. After collecting 800 moons, the player can finally go to the “Darker Side” of Super Mario Odyssey 2 — the Black Hole Kingdom. After a final journey through the alien mothership, they destroy the aliens and achieve world peace, for real this time.
