Megatron was now speeding across the city, destroying everything with his new power.

"There's no point in running. You're all going to die." Megatron said in a bass voice.

Back at the Decepticon base, the heroes and Autobots recovered as they got Flash off the treadmill. Things were not looking good for them.

"What happened?" Barry asked.

"Megatron made himself a speedster. He now has the Speed Force flowing through him." Impulse said.

"He's now faster and stronger than before." Drift said.

"We need to head back to figure out what to do." Batman said.

They then headed back at the Hall of Justice to come up with a plan. They then see on the TV Megatron causing chaos in Central City in a new form.

"Is that Megatron?" XS asked shocked.

"Who's his new tailor? Satan?" Impulse asked.

"Guys, I'm picking a huge amount Energon and Speed Force energy in Megatron's area." Cisco said.

"We need to stop him." Smokescreen said.

"No. Not you guys, us. We have to stop Megatron." Barry said looking at his fellow speedsters.

"What? What do you mean?" Steeljaw asked.

"Megatron is a speedster which means you guys won't be able to stop him. Only speedsters can." Barry said.

"Are you serious? I'm not staying out of this fight." Drago said with a growl.

"None of you guys are speedsters. There's no way you'll be able to keep up with him." Lobo Comando the blue wolf said.

"I'm afraid they're right. None of us would be able to stop Megatron." Superman said.

"Gobber, get Hiccup and his friends. We gonna need their help since now their speedsters." Barry said as Gobber opened a breach to New Berk to get them.

"Sorry amigos, but you're staying here." Piranha said as he suited up as Ripjaw and they ran off.

"Optimus, surely you're not agreeing with this." Ironhide said trying to get into the fight.

"I'm afraid that Flash is correct about us not being able to withstand against Megatron's new power." Optimus said.

They all look at the screen to see how the battle will play. They only hope they're enough to stop him.

Megatron continues his rampage until streaks of lightning pulled everyone away until the streets were empty. Appearing in front of Megatron was the 18 heroic speedsters all glaring at the Decepticon Warlord speedster. Fast Track, Impulse, XS, Flash, Astrid, Stormwolf, Jay Garrick, Hiccup, Wheeljack, Snotlout, Speedquick, Ripjaw, Fishlegs, Ruffnut, Tuffnut, Windstorm, and ThunderDozer.

"Ahh, the fellow speedsters." Megatron said with an evil chuckle.

"You're outnumbered 18 to one." ThunderDozer the Dozeratops said.

"This ends now Megatron." Flash said.

"Once and for all." Wheeljack said.

"You're gonna pay for EVERY innocent life you took." Impulse said.

The speedsters then sped around Megatron and fired bolts of lightning at Megatron. But he withstood the blast of lightning while grinning.

"Is that all you got?!" Megatron shouts as he fires lightning at them as they scattered.

"Just because you have the Speed Force doesn't mean you know how to use it!" Stormwolf said as he throws his lightning dagger constructs at Megatron.

"You'll never beat us all!" Speedquick shouts as he throws lightning shurikens at him.

Megatron chases after them as they sped through the city streets. Each of them trying to stop Megatron.

"Bring it on, tin can!" Snotlout said as he shot fire and lightning combo strike. Fishlegs lightning lassoed Megatron's foot and made him trip.

"The bigger they are, the harder they fall!" Fishlegs said as he sped off with his friends.

Ripjaw then created speed mirages of himself to attack Megatron while ThunderDozer speed ram him. Windstorm created a lightning wind gust at him. Flash and his kids fire bolts of lightning and knock him down. Megatron quickly recovers and sends a shockwave knocking all speedsters down.

"ENOUGH!!!! Decepticons, destroy the city! I'll deal with these pests!" Megatron said as he charges up a mega volt charge blast at them.

As Megatron goes to finish them off, a blast trapped Megatron in a blue bubble that slowed him down.

They turn around to see Cade Yeager aka Timeline.

"Just in time." Cade said as time slowed down to a snail's pace. He then fast forward time them away to safety. Megatron snaps free and roars in anger.

The speedsters were now in the Hall of Justice recovering from Megatron's brutal attacks.

"It appears we bit off more than we can chew." Wheeljack said.

"We need to come up with a better plan." Astrid said.

"There's too many of them, including Megatron." Nora said.

"What we need is more speedsters, but there aren't any more than us." Miko said.

"Yeah, it's not like we can give our speed to others." Tuffnut said playing with an energy ball.

"We would need to expand our minds and powers to connect others to it." Ruffnut said as Barry and Fishlegs eyes widened.

"THAT'S IT! You two are a genius!" Fishlegs said.

"We are?" The twins said. Fishlegs and Flash get to work.

A few minutes later....

The Autobots and the heroes were now in the center of the building.

"I was wrong. It's gonna take more than the 18 of us to stop Megatron and his army. Which is why we're going to share our connection with the Speed Force with you." Barry said.

"Wait, what?" Grimlock asked.

"You're gonna make us speedsters?" Wolf asked.

"Yes. It's an ability we can do, but you'll only have the Speed Force in you temporarily so be careful. Us speedsters we try to open our connection with you so can have super speed." Lobo Comando said.

"Sounds like a plan to me." Drago said.

"That way so there can be more speedsters to take down Megatron and his army." Meena said.

"Okay. How does it work?" Smokescreen asked.

"Just open your minds as we share our connection with the Speed Force." Bart said as the speedster helped hands.

As the speedsters concentrate, colorful lightning sparks off them and hits the Autobots and heroes. A blinding light fill the room.

Megatron was now on his way to destroy more cities when the speedsters blocked him.

"This is your last chance Megs. Stand down." Wheeljack said.

"Or what?" Megatron asked.

"Or we'll force you." Piranha said.

"You and what army? You 18 aren't enough to stop me." Megatron said.

"Good thing we brought some back up." Flash said.

Suddenly, more speedsters appeared. The Bad Guys, Drago, Thrasher, Princess, Green Arrow, Black Wolf, Vibe, Frost, White Canary Optimus Prime, Hound, Bumblebee, Arcee, Strongarm, Smokescreen, Ratchet, Ironhide, Drift, Grimlock, Barricade, and Steeljaw. All of them now one with the Speed Force. Megatron was surprised and angered to see this.

"This end now, Megatron." Optimus said.

"INDEED!!!" Megatron shouts as the two race against each other.

"Alright everyone, separate and stop the cons from destroying the city and protect the people." Flash said as they all broke off.

"So you now have speed, so what! It won't save you!" Megatron shouts as they fight at super speed.

Megatron then pinned Optimus down with heavy pillars with his lightning. He then taunts Optimus.

"How does it feel, Prime? How does it feel, knowing you could've prevented all this, if only you'd killed me when you had the chances? Believe me... that's a mistake I won't make." Megatron said as he fired a lightning bolt at Optimus but suddenly the lightning froze in the air.

"Who's doing this? Who doing this?!" Megatron shouts as the lightning disappeared.

"I am."

Megatron turns around to see who dares stop him from killing his most hated enemy.

It was Nora the Speed Force, Alexa the Strength Force, Bashir the Sage Force, and Dion the Still Force. All of them here to help win the fight.

"You're too late! You can't stop me! No one can stop me with my ultimate power!" Megatron said.

"You call that power? This, is true power." Nora said as the Forces join hands.

The four Forces turned into particles as they flow into Optimus, granting him their powers. Optimus Prime was now sparking yellow, pink, green, and blue lightning all across his body.

"That's... impossible." Megatron said in shock.

"I am the impossible. This is where this ends Megatron." Optimus said as he feels the power.

"Never! I win never admit defeat to a Prime!" Megatron roared as charges at Optimus only for him to grab Megatron and throw him far away with the Strength Force. Starscream and cons were shocked by this. To see Optimus stronger now.

"This is where it ends, Megatron! One shall stand, and one shall fall!" Optimus said as he sped off with Megatron in a flash.

Blue, yellow, red lightning chased purple and red lightning across the streets. Megatron throws a truck at him, but Optimus throws it away with Strength. Optimus Prime teleports with the Sage to sneak attack Megatron. Then he used the Still to freeze Megatron to land a hard punch at him.

As the battle rages on, the Speed Force the other Forces energy bleeds out into the world.

This... is... AWESOME!!!!" Sideswipe shouts as he knocks down a bunch of Decepticons down.

Drago was tearing through the Cons with his new speed, he was loving the feeling of electricity flowing through him. Arcee tackles down many of the cons in her way.

Steeljaw slashes through the Decepticons while phasing through them. But as this happened, lightning continues to crash down on the city.

Strongarm and Bumblebee pound down many Decepticons at full speed. Ironhide was having a blast running at super speed.

"Come and get it punks!" Ironhide shouts as he fires at them.

Cade Yeager then jumps high over Dreadwing and paused him in time.

"Now, Hound!" Cade yells as Hound fired his chain-gun at Dreadwing, who fell backwards unconscious.

Grimlock spin dashed through the cons like a bowling ball against some pins. He then dodged a lightning strike from the sky as he looks up to see.

"What's with the colorful lightning in the sky?" Grimlock asked.

"It's the Forces' energies bleeding into our world." Jay Garrick said.

"That's not good right?" Drago asked.

"No it is not." Fishlegs said scared.

"If we don't find away to end this, our battle will destroy the city." Drift said as more lightning crashed down. People ran for cover from this storm.

Optimus and Megatron clashed into hard as the force knocked them away.

Supergirl, Green Arrow, Flash, and Timeline rushed to Optimus.

"Optimus, you have to end this, before the city is destroyed." Supergirl said.

"I'm done fighting, Megatron." Optimus said as he sits down in meditation.

"Goodbye, Prime! This is the moment!" Megatron shouts as he used his ultimate power to destroy the city and people.

A huge lightning wave crashes throughout the city attacking everyone in the city. Optimus continues to mediate through the Forces.

Cade then begins to reverse time as Optimus focused all his four Forces energies into him. He was now in tune with them. He was one with the cosmic Forces.

"OPTIMUS! IT'S NOW OR NEVER!" Cade shouts as he finished reversing time. Optimus Prime then fired a powerful beam of Speed, Strength, Sage, and Still Force energy at Megatron, which broke his connection with the Speed Force.

"No, no, no, NO!!!" Megatron screamed as his connection to the Speed Force was broken and fell down unconscious, returning to his normal form.

"Lord Megatron, no!" Starscream shouts as they hurried into saving him.

"Curse you Prime! You and your new friends won today but the battle is far from over!" Starscream shouts.

The Decepticons then carry Megatron away as the heroes celebrate their victory. They then looked up to see beautiful colored auras in the sky.

"What is that?" Snotlout asked. 

"It's beautiful dude." Ton-Ton said.

"It's the universe restoring itself." Flash said. All the heroes and Autobots watched as the sky filled with energy. Good once again triumphed over Evil.
