Narrator: Previously in Cog and Auteur's Merged Universe Adventure.

Ironhide (TFA): Sir. We have something which may interest you.

Ultra Magnus (TFA): Go ahead, Ironhide.

Ironhide (TFA): Yes sir.

(Then they show the video of the villains and their new allies)

Doubleleader: We can help you guys to take care of those heroes and their two friends.

Megatron (BW): Who are these two you speak of?

Doubleleader: You will see them when we take care of them.

(At the city)

Cog: Give it up!

Doubleleader: Hahahahahahaha! Don't think you won, Cog! We have backup!

(Suddenly ten vehicles come in)

Vaggie: Oh, crap!

(In the Merged Universe Villains League Base, a dark laugh is heard as the villains are in shock by seeing the figure behind the laugh)

(Present Time)

Starscream (TFA): Even I am surprised...

Gray Mann: Who are you?

????: I am Megatronus Prime, also known as The Fallen. I am the one who merged the universes into one.

(The villains get even more shocked by hearing this)

Blackarachnia (TFA): So it was you.

Megatronus: Exactly.

Shockwave (TFA): How did you do that?

Megatronus: It's a long story.

(Flashback)

Megatronus: It all started when I lost my battle against my universe's Optimus Prime, Bumblebee and the other Autobots, getting destroyed in the process.

(Megatronus is seen at another world, receiving greater powers)

Megatronus: After my supposed death, I ended up in another world, where I received godlike powers which are far more powerful than a Prime.

(Then Megatronus is seen merging the universes)

Megatronus: At first, I was planning to return to my own world, and destroy it.

(Flashback Ends)

Megatronus: But I decided to simply merge the universes where you originally belong, turning them into one. And with your help, I can finally take over the merged universe!

(The villains get extremely shocked)

Waspinator (TFA): Unbelievable...

Megatronus: And above all, I can see how eager you are to destroy the heroes who insist on standing in your way. (pulls out his dark staff) Let me show you how I did what I did.

(Meanwhile at the heroes' base)

Sentinel (TFA): Those disgusting villains got lucky to have escaped alive. Next time, we will destroy them!

Optimus Primal: What should we do next?

(Then Cog, Auteur and the characters seen in the previous episode come in)

Angel Dust: Hi, Alastor.

Alastor: Angel Dust. It's been so long.

(They have a hug)

Scout: Spy. Pyro. Engineer.

Spy: Scout. Soldier. Heavy. Demonman.

(The mercenaries do a high five)

Bumblebee (TFA): Sari.

Sari (TFA): It's been so long, Bumblebee.

Charlie: Where did you find them?

Auteur: We found them in the jungle after we engaged Starscream in a high speed chase and beat him.

Cog: Unfortunately, he escaped.

Sentinel (TFA): (to Optimus) Why didn't you help them to capture Starscream?

(Then the ground starts shaking as more universes are seen merging into the already merged universe. As the merged planet is seen getting twenty times bigger)

(Back to the Merged Universe Villains League Base, more villains appear)

????: What just happened?

????: Back to life, huh? My lucky day!

????: What's the meaning of this?

????: I could ask the same!

Megatronus: Hahahahaha! HAHAHAHAHAHAHA!!!

(More universes are merged. And this means more villains. However, wherever there are villains, there are heroes. Where could more heroes be?)
