Here we see Freelancer holding the lantern and we see Discord, Deadpool, Pinkie Pie, and the Mask at a pizzeria and they are eating pizza.

Pinkie: "Whatcha got there?"

Freelancer: "It's a lantern."

Deadpool: "We can see that but what is it?"

Freelancer: "You all remember Gen 1 of Monster High?"

Discord: "Oh we love that until Disney decide to make a copy cat called Descendants and them cancel the whole thing."

Freelancer: "This is the lantern containing the genie Whisp and she grants 13 wishes."

The Mask: "Wait a second, this reminds me of the time when our chums from Death Battle made Vegito and Gogeta to fight each other."

Deadpool: "Hold up? You mean they used the power of the Dragon Balls to make Vegito and Gogeta fight each other?"*realizes*"You're gonna use those 13 wishes to make 13 battles between fusions are ya!?!"

Freelancer: "That's right my tumor riddled friend, I'll use these wishes to make battles of multiple fusions happen."

Deadpool: "Sweet! This is gonna be awesome. Although we need to finish up the Rick and Morty marathon first before we move onto fusions."

Freelancer: "Gotcha. But first let's show them a sneak peak of the fights."

Deadpool: "Are you gonna use fan made fusions like Goffu and Shadic?"

Freelancer: "Of course, fan made or official I'll even include fusions of all kinds like Super Bat and Composite Superman and Omni-lander or Lord Drakkon."

Suddenly we see Rick and Morty come out of a portal and look at Freelancer and the others.

Rick: "Don't do those fights!"

Morty: "We don't want to do those fights!"

Freelancer: "What's going on?"

Rick: "Look Freelancer, we do not want to fight the Avengers."

Morty: "I don't want to see Iron Man die again, especially in my hands."

Rick: "Or any Undertale character get slaughtered."

Freelancer: "I see where you guys are going with this. To be honest if I had the Undertale game I wouldn't do a genocide run either, even though you can remove the consequences from the game's files that doesn't mean they're gone."

Morty: "Yeah without consequences what are we living for?"

Freelancer: "As for the Avengers I'd say I seen Tony get killed one too many times and I would not want to see him die again."

Rick: "Yeah he might die in the universe where he went to Sakaar instead of Hulk cause the Soul Stone needs a sacrifice to get the stone."

Freelancer: "Alright, I understand."
