Then Tirek tells them that they never make him Force sensitive, and never gets to make him wield or construct his own lightsaber.

Stuingtion's engines explain the real story
But after hearing this new info on the Trainsformers, Brian then points out that Stuingtion's Engines could know about it. While they decline they don't know, Twilight is convinced they lied to them. As Brian states they didn't know anything about the Trainsformer's true history. Until T.C. looses patience and tells them they did lie. But they didn't give the whole story. As the engines explain how they knew about Megatrain resurrecting Tirek and how they combined their powers to create Cybertrain but then a war broke out from it and Tirek betrayed and threw away Megatrain because he knew the truth. As Twilight asks what is the truth. Which the engines explain that Trainsformers are on the edge of extinction. They're scattered across the galaxy, and they're a dying race. And the only thing that matters for them is to grab and hide, wherever they can, before somebody else, beats them at the finish line. As the engines apologize for not being honest but they only did because of what was to come. They don't have the whole idea, but they do know the battle is not like any other that they've every been in. It will take more than what they had to win it. But Fluttershy practically tells off Willy and tells him and the engines to leave and never return, leaving everyone in the room speechless at this turn of events. While Willy, with hurt feelings and feeling betrayed, agrees. Stating they'll go home to Cartoon World and never return and note they aren't really friends, more like expendable assets. As all of Stuingtion's engines, sad, heart broken, and no longer feeling like friends leave the castle.
But the Eds, Figge, and Cera are shocked at The Royals, Fluttershy, Twilight, and Brian for out for selling Stuingtion's Engines all because of a lie and start to chew them out. But Brian then grabs Eddy and tells them it's the end of the world. And Cera states she refuses to help if Stuingtion's Engines are not going to help, which Figge, and the Eds conquer. As Figge and the Eds then scold the formers stating that the engines knew of what was to come and only lied to protect them. As Eddy states that Stuingtion's Engines were friends with him and the other eds longer than the others as Double-D states that they would rather be with true friends and not walk aimlessly around. As Figge then points out to Fluttershy about how Willy stuck up for her many times before and how she risked her own life to bring back Willy. As he tells her she should be a ashamed of herself for selling him out. While Cera then angrily notes about how Stuingtion's Engines helped the team out on many adventures by providing them firearms, and other cool gadgets, which makes the Royals feel pity for what they said to them. As they begin to leave the room. While Brian tells to go ahead and leave. While Figge sarcastically agrees, not before slamming the doors shut with a long bang. But then the royals have a change of heart and decide to go and find them. While Brian and Twilight are confused by this, The Royals state that Cera is right and it wasn't right for them to sell them out like that. While Vinny states friends who lie must be in exile, but Barret notes doing so will only leading them to do something they'll regret. As Brian then asks what will they do about Solar Flare as Luna notes options are being considered. In which the Ghost Crew also leave, not before Zeb gives Brian a kick in the groin.

But before Q tells them that Clocker is with them and are in a sub, Eddy tells them they're finally learning something for a change. Then, Q beats him up with his cane and takes out a Trainsformer watch that killed Chancellor Ferdinand and tells them that the end is near, and if they don't help, the Earth will be destroyed by Cybertrain.

As a clone tells the general the chamber is falling, the sucking Earth progress is still going. As the chamber's still falling, it is grabbed on by some vines, and they all land on the floor. And the Trainbots and Deceptitrains begin battling, and TIE tells Twilight to grab the staff. And Twilight runs for it as the chamber begins sliding down, it is caught, and TIE and Gordon battle Megatrain, as Twilight runs for the staff. Angel Death senses her and tells Megatrain to kill her. But Thomas cuts off Megatrain's right arm, but Megatrain force chokes Thomas with his remaining arm, and tells him that he, Megatrain, and Angel Death could be the new rulers of Cybertrain, but Thomas tells him that wasn't gonna happen. Then he spits in his eye, and cuts him in two. As Twilight grabs hold of the staff, the chamber breaks loose and it falls and Twilight falls, and so does everyone, at the meantime Percy manages to kill Raul, and Willy kills Starsmoke. And Thomas kicks Twilight up and she manages to grab the staff. And Spike tells her not to let go, and Brian attacks Angel Death but she manages to stop him with her force lighting, and tells her that he could be a good apprentice, and he can be Darth Manacore again. But Brian tells her to say hello to his wife, and Sylveon throws his lightsaber and impales Angel Death! And she drives her saber up and then cuts her in two. And Twilight pulls the staff out, and the energy transfer stops and everyone cheers. But the chamber continues falling, and once everyone comes together TIE fires and manages to slow down the time, as Thomas grabs them as the chamber collapses to the ground, everyone believes they all died. When in fact they come out of the smoke, still alive and well!
But just as it looks like that's the end of the battle, Tirek then appears with a huge army and demands Brian to surrender or he will die while the Princesses will be sent to Tartarus. And if Brian does surrender, he'll still die and the Princesses will still be sent to Tartarus. But then Brian states he doesn't take orders from a coward as he tells Tirek that he thought himself all high and mighty. But he hides behind his soldiers, expecting them to do his work. But the truth was, he's weak and Tirek can't even help his own comrades, he just sends assassins to kill them, instead of doing it himself. And He'll never get rid of the royals, because he's just an old wimp. And that the truth is: if Tirek faced them, right now. He would loose. After a moment of silence, everyone opens fire at Tirek who then starts up a shuttle and flies it over the battle but then when things start to look bad, the Clone Troopers, the rest of the others, and the Insect Bots race in and join the fight as our heroes fight the many troopers as Brian takes control of turret and guns several of them down as Tirek continues trying to kill them all with his shuttle. As the team continue to fight, Celestia is minorly injured when some stray bullets hit her in the shoulder as Brian then charges one of the tanks armed with a Molotov cocktail as Shining Armor takes control of a 20mm cannon. But then a blast from the tank causes Brain to fall off his horse as one of the shuttle side gunners shoots him in the leg. But Brian manages to clear out of the tank's way as he throws the Molotov cocktail onto it, making flames erupt on the tank and he then shoots out the tank crew and hops inside it himself and gets it started up.
Just as Tirek's shuttle turns back around Brian gets the tank driving at it as Tirek tries to blast it with a rocket and Brian returns fire but neither have a direct hit. As Celestia shoots out the side gunners on the shuttle as Tirek swing sit back around for another go, as Brian sets the tank at full speed. Leaving both Brian and Tirek in a deadly game of chicken as they both continue to draw fire at each other, as Brian manages to shoot out the co-pilot in the shuttle and with a Battle cry, Brian charges the shuttle at full speed as Tirek is getting majorly injured from the hail of bullets from the tank's side turret. As everyone watches in concern, while Brian yells out: "SCREW YOU!!!" while Tirek screams in shock and fright as the tank and shuttle collide and the shuttle explodes into a fiery inferno! Then when the fireball clears, not only is the shuttle completely destroyed but Tirek is nothing but a burning corpse. As Brian triumphantly exits the tank declaring that Tirek will no longer bring harm to them ever again. As Cera takes care of the body.
Twilight returns to normal/"Sing a Song"/Ending
Then, suddenly Twilight's wings disappeared. As Hen is shocked, Twilight tells her she can use them whenever she feels like it. And soon, Brian apologizes for kissing her back in the sub, as Twilight notes they should just stay friends. And they share a brief hug. And Trax tells the other Trainbots it's time to rebuild Cybertrain and Earth and that it's time to go home, and they all fly off to Cybertrain, as heroes bid farewell to them. Then Edd asks Cera what she did to Tirek, she tells him that she cremated him, and shows his ashes in a jar and plans to dump them in the sea, and will send a letter to his family, then Skeeter asks the group to now what they're suppose to do. Soon, back home, they attend the Wubb Girlz's concert. As the Wubb Girlz sing their hit song: "Sing a Song" as the film ends.
