Opening/During the Age of Apocalypse/Meeting with General Thunderbolt Ross

Here is how the Avengers return in Mickey Mouse, the Avengers, and the Age of Ultron.

The film starts in 3600 B.C., an aged En Sabah Nur is about to undergo a transference into a younger body.

The Egyptian worshipers: (chanting) En Sabah Nur!

Little did En Sabah Nur and his horsemen realized, Horus and the royal guards make ready for the attack as they went inside a technologically-advanced pyramid that works off of sunlight.

Inside the pyramid, Death was testing the ability of the regenerating mutant's body with a knife.

Death: Soon, you will rule forever, My Lord.... (as En Sabah Nur lied down and Death came to the young mutant) Sleep. (as he rested) Let the transfer begin.

The moment the body transfer began, Horus signaled for the guards who're betraying En Sabah Nur.

Horus: It is time.

With that, Horus and the resistance fought the Horsemen of Apocalypse.

Famine: Watch over him!

Horus: Down with the false god!

Famine: Horus!

So with that, Horus led the resistance to the attack.

Famine: Protect our god!

Horus: Attack!

Famine made sure the transeration completes, the other horsemen fought off Horus and the guards.

Famine: It's just about done!

Horus: By the power of the Egyptian Gods, I sentance En Sabah Nur and his horsemen into kingdom come!

With one spell to cast, Famine finished the transfer as Horus trapped her along with the other three horsemen in their Tombs of Eternal Rest as well as En Sabah Nur himself inside.

Horus: At last, the age of En Sabah Nur is done.

Finally, the title showed "Mickey Mouse, the Avengers, and the Age of Ultron" as the screen fades into pitch black.

Years later at the Magic Kingdom of Disney, Mickey Mouse and his friends were having a banquet.

Mickey Mouse: Oh boy! Isn't this banquet swell, Minnie?

Minnie Mouse: It is so beautiful.

Just then, Mickey notice General Tunderbolt Ross getting his punch.

Mickey Mouse: General Ross?

General Thunderbolt Ross: Long time no see, Mickey.

Goofy: Gwarsh, General. What're you doing here?

Sylvia Marpole: The Mind Stone?

Steve Rogers: That's right, Sylvia.

Tony Stark: We've gathered everyone together, and we've got a lot more with us.

Max Goof: Woah! There's more Avengers besides you guys?!

Bruce Banner: Yeah.

With that, the entire Avengers gathered together to see Mickey and his friends.

Red She-Hulk: Hey, Mickey, remember me?

Mickey Mouse: Betty Ross, is that you?

General Thunderbolt Ross: That's right, Mickey, she's the Red She-Hulk while I'm the Red Hulk.
