Playstation All-Stars Style Smash Stages

[Zzuxon]

I was doing research on Playstation All Stars Battle Royale. Somewhat to my surprise, It is a very well thought out crossover game, and I've gained a lot of respect for its devs. One of my favorite things I discovered about the game is the way stages work. They start out the way Smash stages do, a location from a series. But, midway through the match, the location is invaded by elements from a different series. It'd be like if halfway through a match on Skyloft, Bowser's Airships showed up and began firing on the city.
That is what this thread is for, for people to come up with PSASBR style stages based on Nintendo series. Include

Stage Name: This is the location of the stage.
Primary Series: The series the location is from.
Secondary Series: The series that invades the location.
Intrusion: How the invasion occurs, and what happens.

Here are some I came up with:

Bowser’s Castle
Main Representation: Super Mario
Secondary Representation: Sonic the Hedgehog.
Intrusion: Dr. Eggman’s forces attack the castle.


Skyloft:
Main Representation: Legend of Zelda
Secondary Representation: Super Mario
Intrusion: Bowser’s Airships arrive and open fire on Skyloft


Kongo Jungle:
Main Representation: Donkey Kong
Secondary Representation: Ice Climber
Intrusion: The background freezes over. Snowmads and Ice Climber enemies alike appear on the stage.


Saffron City:
Main Representation: Pokemon
Secondary Representation: Legend of Zelda
Intrusion: Does that Moon have a face?


Colosseum:
Main Representation: Fire Emblem
Secondary Rep: Advance Wars
Intrusion: A door to the arena blasts open as Advance Wars units storm the field.


The Maze
Main Representation: Pac-Man
Secondary Representation: Donkey Kong
Intrusion: Arcade Donkey Kong appears in all of his glory and begins rolling barrels through the Maze.

Thought of ideas for such a thing some time ago. Here's a few:

Pikmin/Pokemon - In a generic forest environment where pikmin can be seen scampering and carrying objects in the background, until a group of them carry in a pokeball and release insert pokemon and start battling it.

Wii Play/Advance Wars - Where the stage takes place in "Find Mii." Mii's walk around and stare at the fight until Black Hole tanks and infantry start pouring in and capturing the buildings. The Miis retaliate with their own "Tanks!" as such until they win.

Majora's Mask/Twilight Princess - Where the fight takes place on the clock tower and the moon descends over the course of the battle. Once the moon is about to crash, twilight portals would appear and suck it up (along with parts of termina) and spew out Twilight Princess related pieces. Zant would also appear. That stage resets itself when the after the Song of Time is heard playing and you're warped back to the beginning.

Yep these would be fun

Please pardon the bump...
Ruined City Escape
Primary Series: Mega Man
Secondary Series: Sonic the Hedgehog
The stage takes place in the intro stage from Mega Man 7 with the Mad Grinder watching the fight and wrecking the city. Later the G.U.N. Truck from Sonic Adventure 2 crashes into it and various G.U.N. Soldiers try to fend it off.
