Soon...

The Waverider soon arrived at the oil platform to stop Anti-Matter and his gang. Everyone got into position. Cisco, Ray, Constantine, Behrad, and Zari would deal with what they built while the others deal with the Ultra Rogues.

"Alright everyone. You all know the plan, so let's move in and stop them." Oliver said as they charge in. One of the security cams spotted them. Brainstein and Anti-Matter saw this and were not happy.

"Grrrr, they've found us! What do we do now?" Brainstein asked.

"Get the others to hold them off long enough for the portals to open. They can't stop us." Anti-Matter said as he rushed off to the heroes.

Back with the heroes, they managed to get pass the base's security system and we're heading to the machine when Anti-Matter and his pals stopped them.

"Well, well, well. Looks like we have some pests in our home. Time to do some exterminating." Inferno said as he fires up.

"Whatever you're up to... it ends now." Green Arrow said pointing his arrow at them.

"I think not Green Arrow. My plan is already set into motion. You heroes won't stop us this time." Anti-Matter said.

"Mind telling us what you're doing? We already know you're building a portal. Why though? To summon some allies?" Flash asked.

"Very well. My portal is not to summon help, but to create. This portal is going to turn everyone into their own dark, evil, cruel self. Light to dark, good to evil, kindness to cruelty. The world will become its dark self." Anti-Matter said.

"You can't do this. There are innocent people all over. Husbands, wives, and children. They don't deserve this." Supergirl said.

"Too bad. The world will be ours to control." Anti-Matter said sinisterly.

"Yeah, that's not gonna happen." Flash said. He then ran into them, scattering them.

"GET THEM!!" Anti-Matter roared as he gets up and fires at the heroes with his staff. The heroes scatter as the battle began. Black Wolf howls at Spyclops, sending him away. He then turns to Vibe, Atom, Behrad, and Zari.

"We'll distract them while you 5 shut down that portal." Flasheart said.

"On it." Vibe said. He then opens a breach that teleports them to the machine.

The heroes continue their fight with the Ultra Rogues. Powers, skills, and weapons, firing everywhere. Aqualad and King Shark was battling it out with Inferno and SharX, The three werewolves and Black Canary fought Adam Acid and Retox. Steel, Tigre and Rayburn Jr were fighting Tremor, strength vs strength. Frost, Mick, and Dig were battling Driller, Toxikita, and Invizable. Flash was running and fighting Electroloyzer at super speed. Supergirl was battling Psyclone in the air. Green Arrow was battling hard against Anti-Matter. All were battling hard against each other. Green Arrow jumped and spin kicked Anti-Matter off balance. He recovers from Green Arrow's attack.

"Give up, Green Arrow! You CANNOT stop what has been set in motion!" Anti-Matter said as he fires again at Oliver. Oliver continues dodge and fire arrows at Anti-Matter.

"You'll fail as always." Green Arrow said.

Meanwhile with the four geniuses and warlock are heading down to the machine to shut it off. They finally made it to see Terabyte, Spyclops, and Cyborg Brainstein in the room. John then casted a ice and plant spell trapping the three tech villains. The 4 get to work.

"Better hurry, mates. That spell won't hold them forever." John said as he tries to contain them.

Cisco, Zari, Behrad, and Ray begin to work on the machine. Zari begins to hack into it to shut it down.

"Whoa. Guys? This machine isn't just going to open a portal over here. It's going to open portals over every city in the world." Zari said looking at the computer.

"There's gotta be a way to shut it off." Behrad said looking at the machine.

"If that machine finishes booting up... it's game over." Cisco said as he hacks into the computer. Ray tries to help and sees a blue crystal glowing in center of the machine.

"Wait, that crystal in the power center. If we remove it... it should shut down the machine." Ray said as he goes to pull it out, but ends up shocking his hand. He looks closer to see a force field around the crystal.

"It looks like a force field is protecting the crystal.  You guys think you can shut down the force field?" Ray said.

"We're on it." Zari said as she and Cisco start hacking the shield. John was still struggling to keep the three tech villains are trying to break free.

"Anytime now!" John said as he continues to hold them.

After a few clicks of buttons, the shield dropped and Ray grabbed the crystal and the machine begins to power down. The portal begins to shrink. The three villains finally broke free and knocked John to the wall.

"John!" Zari exclaimed. Behrad then sent a wind tornado at them, sending them far away. Terabyte manages to dodge the tornado attack.

"Better hurry up with shutting it down!" Behrad said as he begins to fight Terabyte. Terabyte fires a blast knocking Behrad away and fires more bolts at the others. He knocks Atom down and plugs the crystal back in. The portal grows bigger and soon portals started to appear over every city.

"Face it heroes, you cannot stop this coming." Terabyte said.

Back with the others outside, the heroes are close to stopping the villains when portals started to come out of thin air. Flash, Green Arrow, and Supergirl look up in horror while Anti-Matter grins evilly.

"Finally! Soon the world will plunge into eternal darkness!" Anti-Matter yelled. Flash then grabs onto Green Arrow and Supergirl.

"Not if we stop it." Flash said. He then phased the three of them down to the machine. Anti-Matter saw this and was shocked and angry.

"NOOO!" Anti-Matter yelled. He quickly teleports down to the machine.

Flash, Green Arrow, and Supergirl arrived at the machine seeing it almost done booting up.

"We have to stop it. Everyone! On my mark, fire your powers on that machine." Oliver said. Ray manages to grab the crystal and prepares to fire at the portal. The heroes then together fire their powers at machine, causing it to malfunction. Anti-Matter arrived too late to stop them. He saw the portal ripple and finally explode. It sends a huge shockwave across the place, knocking everyone down. Anti-Matter gets up to see the machine destroyed.

"NOOOOOOO!" Anti-Matter roared as he sees his plan fail. He turns around to see the heroes looking at him and Terabyte.

"It's over. You failed." Green Arrow said pointing an arrow at him.

"No... this... this is just the beginning." Anti-Matter  said. He snapped his fingers and he, and Ultra Rogues teleported away.

"They got away." Behrad said.

"Don't worry. Next time we'll get them." Kara said.

"At least we stop them using that portal." Barry said looking at the wreckage of the machine.

"And we got this." Ray said holding the crystal.

"Oooh. So pretty." Zari said as she goes to touch the crystal, but Cisco grabs it.

"Hey, watch it. This crystal is powerful and dangerous. It best if we get this to S.T.A.R. Labs to analyze it." Cisco said.

"Good idea." Barry said.

"Fine." Zari said rolling her eyes.

"So... I guess that's it then." John said.

"Let's head back then, now that we're done here." Oliver said.

"I hope us destroying that machine while it was activated didn't cause any problems." Kara said.

"I'm sure it didn't." Behrad said.

They all headed back to the Hall of Justice. Unknown to them, a breach began to open in windmills field. The heroes were going to get some visitors from a different universe.
