It consists of a platform similar to Final Destination again but it is a much larger stadium than before. The background has a audince and clouds. When the Ninja's and Armys invades it shares it's background with the Halberd stage again.
The stage beigns with a battle between Mario, Kirby and Link. After the brawl, the Army suddenly invades the stadium, and Mario, Kirby and Link, along with Peach, Zelda and Rosalina, end up going up against Differant creatures some resembling the Subspace. Eventually, the Ninja Sukai appears, carrying a Trophy Box. Mario gets hit and knocked away and Kirby or Link ends up fighting Paint Petey Piranha, who holds the princesses captive. Kirby or Link manages to rescue one of them, but Wario and Waluigi suddenly appears wielding a Dark Cannon. Wario suddenly notices the other princess and fires his weapon at her instead. Reduced to a trophy, the other princess is taken by Waluigi. The stage ends with Kirby or Link escaping with the princess he saved and a bomb exploding, taking the stadium to Ninjai. Midair Stadium cannot be played again until the game is cleared.
