Ironhide and the other Autobots took the ponies into the war room to explain exactly what they're up against: The Decepticons. He began to explain the different kinds of Decepticons there is.

Ironhide: These Decepticons are nothing more than savage brutes that like to destroy everything in their path. INCLUDING ponies. Now, in my class, you wil know exactly what Decepticons you will be seeing out in the battlefield.

1. Megatron, their leader. He is power hungry, pure evil, and unequaled in battle except for Optimus Prime. He would like nothing more than to make all Equestrians, that's YOU, his slaves.

2. Starscream, the Decepticon's air commander and Megatron's second-in-command. He is a crafty, cowardly, and self-serving adversary. Don't turn your back on Starscream, unless you want something sharped buried in it.

3. Devastator, a Constructicon combiner that pulverizes everything in its path, sucking up bots like a deranged vaccum cleaner. If you encounter this one, you will highly likely die.

3. Brawl, a massive Decepticon that turns into a tank. He has 2 razor sharp blades atacked to his knuckles. He also has missile launchers, a cannon, and is heavily armored. If you encounter this one up close, you're DONE for.

4. Shockwave, He was the one that attacked your military base, and he did it well. He is a savage brute that loves the smell of destruction. He is more than willing to kill a few ponies in his path.

Ironhide: These Decepticons, and lots more not mentioned in the video, are a force to be reckoned with. Wait a second, I hear something.

Optimus: All Autobots, make your way to the front gate. The Decepticons are coming! Quickly.

Ironhide: Prepare for battle, guys.

Fluttershy: I'm scared. I hope they don't see me.

Rainbow Dash: Come on, guys, let's go.

The Mane 6 and the Autobots saw a large Cybertronian jet smash through the window and transform into the evil Megatron, the Decepticon leader.

Megatron: HAHAHAHAHAHA!

Optimus: Megatron, we meet again.

Megatron: Yes, Optimus. We do. And you will NOT get in the way of my plans for domination of Equestria and Cybertron. Do you know how long I've waited to find the Allspark and get my revenge on you Autobots?

Optimus: Looks you're going to have to wait a lot longer.

Megatron turned his arm into his fusion cannon and attacked Optimus Prime. Prime grabbed Megatron by the shoulder and punched him in the face. Megatron retalitated by hitting Optimus and then kicking him into Celestia's throne, smashing it and the wall. Princess Celestia got out of the way just in time. Megatron charged at Optimus, who got back up and lunged at Megatron. The ponies could only watch as Optimus and Megatron continued their battle.

Soon, the other Decepticons, Starscream, Shockwave, Brawl, Blackout and Bonecrusher arrived. They arrived to do battle. And a battle it was. Ironhide fought against Brawl, Ratchet battled Bonecrusher, Bumblebee fought Starscream, and Arcee took on Shockwave. Blackout meanwhile attempted to grab the Allspark.

Ratchet: I hope you have a plan, Optimus. I could use help.

Optimus: A little busy right now.

Optimus punched Megatron in the chest, but Megatron fought back by firing his fusion cannon at Prime. Prime was caught in the explosion, sending him flying into the statue room. Optimus and Megatron continued their battle, smashing several statues in the process. Princess Celestia's royal guards arrived and began attacking Megatron.

Megatron: Fools! You really think you stand a chance against ME? How pitiful!

Megatron swatted most of the guards out of the way and blasted at a few with his fusion cannon. Megatron turned his attention back to Optimus, and grabbed and slammed him into the floor. Optimus took out his Ion Blaster and began shooting at Megatron. The bullets hurt, but they also made Megatron angrier.

Megatron's hand turned into a flail and he started battering Optimus Prime with it. Optimus took out his Energon sword and stabbed Megatron in the leg with it. But Megatron managed to get up and pounded Optimus. Megatron then turned his attention back towards the Mane 6. Megatron smashed through a wall, and came towards the ponies.

Megatron: FOOLS! YOU CAN'T ESCAPE MEGATRON! GIVE ME WHAT IS MINE! GIVE ME THE ALLSPARK!

Applejack: I'm NEVER giving you this Allspark, Megatron, so just give up.

Megatron: Oh...so unwise. Then I'll take it...BY FORCE!

Megatron attempted to step on Applejack, who avoided Megatron's attacks. Rainbow Dash flew all over Megatron as he did with Starscream. But Megatron was much more clever than Starscream, and grabbed Rainbow Dash and slammed her to the ground. Fluttershy hid, and even Pinkie Pie was scared. Twilight attempted to use magic to fight, but that wasn't enough to deterr Megatron. Optimus arrived back in the battle and lunged at Megatron.

Optimus: Go! You have to destroy The Allspark. Quickly! GO!

Ratchet: I'll escort you to ponyville. Hop in!

Ratchet turned into his vehicle mode and 4 of the Mane 6 got in him while the other 2 got in Ironhide. They drove over to Ponyville for the final showdown against Megatron and the Decepticons. Megatron broke free of Prime's grasp, turned into a Cybertronian Jet, and made his way towards Ponyville.

Meanwhile...

Optimus Prime quickly changed into truck and began to head for Ponyville himself to stop Megatron. But it was hard to see where the others went because all the trees in the forest were blocking the way. Suddenly, a large tank started firing at Optimus. Optimus dodged the explosions as fast as he could. Then, the tank turned into a gigantic Decepticon known as Brawl. Brawl was an enormous Decepticon that had 2 missile launchers, a cannon and was heavily armored. He also had long sharp blades on his knuckles.

Brawl charged at Optimus, who changed into robot form to take on Brawl. Brawl lunged at Optimus, and both tumbled through the forest, knocking down trees as they went. They both got up, and Brawl open fire with his missile launchers. Optimus avoided the missiles and the explosions that followed. Prime took out his dual energon swords and sliced off one of Brawls missile launchers. Brawl attacked with his blades, but Optimus' agility helped him avoid those.

Brawl took out his cannon and opened fire, and a missile hit Optimus, sending him flying through several trees. Optimus got back up and jumped over Brawl, and sliced his head off. Brawl's headless body crashed to the ground. He was dead. Optimus turned back into a truck and continued his drive over to Ponyville.
