Disclaimer: I own nothing

Batman is sitting in the Batcave when Green Arrow walks up behind him and sets down in front of him a glowing green rock. "What is this?" Batman said.

"I presume it is Kryptonite. It was given to me by an Argus agent named Patrick Morgan. He said it was in case we were to get into a fight with Superman." Green Arrow said.

"I'll take the precaution. Some kryptonite armor just in case. But I doubt I'll need it."

Meanwhile, in Athens, Greece, Ares is watching. "Well then, we'll have to remedy that won't we. The Legion has been working on something. I think I should tip off old Batman and Superman. Let's bring them together." He picks up a gorilla-shaped piece. "And you, my ape friend, are going to make it happen. Go to work…" He puts down the piece. "Grodd."

In the Batcave, Supergirl runs up to Batman who has finished his Kryptonite armor. "Uh, Bruce…"

"Just a precaution in case I have to fight Clark."

"Uh okay. Listen we received word that Gorilla Grodd has made a plan to enslave all of humanity."

"Get the Justice League together. Grodd must be stopped."

Meanwhile, in the Hall of Justice, Wonder Woman walks up to Superman. "Clark, we got intel saying that Grodd has put a plan into action to enslave humanity."

"Get the Justice League together. We go to Gorilla City."

A few hours later in Gorilla City, Gorilla Grodd assembles the Legion of Doom, which consisted of Bizarro, Catwoman, Cheetah, Black Manta, Solomon Grundy, and Captain Cold. "Alright my fellow villains, I have a plan to enslave the Earth and give you six whatever you want. I have retrieved technology from Brainiac."

"So Grodd," Catwoman said, "What do you plan to do with this technology?"

"Once I mastered it, I will use it to amplify my telepathic powers. And then I will put the humans in their place. And then, you six can have the Earth, and I will lead my Gorilla Army to conquer the universe! The Earth will be yours, and then all worlds will kneel before Emperor Grodd!"

"Okay, I heard enough." Catwoman said. She took her whip out.

"So did I." Captain Cold said. He pointed his gun at Grodd.

"Traitors!"

"Informants." Just then, Batman's faction of the Justice League broke in. Cheetah and Solomon Grundy then attacked. Supergirl blasts Solomon Grundy with her heat vision and Shazam blasts him with his lightning powers, Solomon Grundy breaks free and grabs Supergirl's face and throws her to the ground and then punches Shazam into the sky. Solomon Grundy is then hit hard by Supergirl who keeps punching him in the face until Zatanna casts a spell that banishes him back to his swap where he would be trapped there forever.

Cheetah managed to capture Black Canary, who tried to scream at her but is futile, until Green Arrow catches her in a net arrow. She uses her claws to break free. Then Flash grabs her and takes her into the jungle.

Just then, Superman's Justice League faction bursts inside. Black Manta and Bizarro attack them. Hawkman and Hawkgirl attack Bizarro and they keep hitting him. Doctor Fate then opens a portal into deep space where Bizarro is then banished. Green Lantern and Wonder Woman then manage to secure Black Manta long enough for Aquaman to knock them out. "Catwoman, Captain Cold, you guys were great." Superman said.

"You." Grodd said.

"Hello Grodd."

"You may have delayed my plans, but I will succeed. All worlds will kneel before Emperor Grodd!"

"Keep dreaming." Batman said.

"Bruce, this is none of your business. Renegades are not aloud."

"So this is what his plan is."

"What whose plan is Grodd?"

"You'll find out soon enough."

"Martian Manhunter, take him in." Martian Manhunter carries Grodd off to an A.R.G.U.S. prison. "Bruce, your insurgents could've cost the lives of hundreds of apes here today. Keep this up and the Meta-Human community will be scared out of their minds."

"But we didn't Clark. And you think Meta-Humans need to be registered? That having them sign a piece of paper will keep them safe?" Martian Manhunter then floated down from the ceiling.

"Yes. And I will protect them from you." Batman's armor started to glow a bit green. "So, you got your hands on a bit of kryptonite."

"You really want to do this?"

"If it puts you in your place, yes. Whoever is on my side get behind me right now!" They started to pair up. Batman vs Superman. Supergirl vs Wonder Woman. Flash vs Green Lantern. Cyborg vs Aquaman. Green Arrow vs Hawkman. Black Canary vs Hawkgirl. Zatanna vs Doctor Fate. Shazam vs Martian Manhunter.

Meanwhile in Athens, Greece. Ares watches the tension rise. "Phase one complete. Commence Phase two."
