To unlock this stage, you must complete the " When Lightning Strikes" event.
Normal Form
Like the Kalos Pokemon League Stage, this stage's terrain changes depending on the type of Pokemon watching in the background. It starts off with a normal terrain, with two smaller platforms floating above the main platform. Watch out for the warning symbol that will appear in the large screen in the background. The symbol there will tell you what kind of terrain is incoming. For each elemental transformation, the platform will always return to normal before shifting to the next elemental terrain. The cycle of the terrains seem to be random as well.
Ice Terrain
Players lose traction on the floor. It's possible to slide off the platform.
Electric Terrain
The platform changes to an industrial-like setup with two fast conveyor belts that can throw players quickly offstage. During this terrain, it's better to fight in the middle or on the platforms above.
Wind Terrain
With powerful winds blowing upward, players' descent will greatly slow down, allowing vertical smashes more easily.
Ground Terrain
This transformation is generally for cosmetic purposes only and has no active hazard.
Omega Form
The stage has its normal terrain and main platform intact. There will be no terrain changes or active hazards.
