The Great Iniquity

Episode 1 of Nightwing & Batgirl.
Nightwing, Batgirl, and Black Canary fought Roulette and her henchmen in stopping an illegal underground wrestling tournament she is sporting. They were disguised as the audiences, and later when the first match started, Nightwing, Batgirl, and Black Canary then showed up into the ring. 
"You dare ruin the show?", Roulette told them.
"If you don't knock out this act any sooner, you might be the ones getting knocked out.", Black Canary told her.
"We'll see about that.", Roulette replied.
"Come down here and fight.", Black Canary challenged.
"As you wish.", Roulette accepted.
First, Nightwing, Batgirl, and Black Canary took down the wrestlers involved, namely Bane, Blockbuster, KGBeast, Killer Croc, Bizarro, Hellgrammite, Hellhound, and Atomic Skull. With their reflexes, Nightwing and Batgirl were able to evade their attacks and later outsmarted them. With her Canary cry, Black Canary knocked them down unconscious. Later, Roulette and her henchmen came in and battled the heroes. After a short fight, Roulette was later knocked unconscious by Black Canary. She was tied with a Batrope by Nightwing. Later, the police arrested her and the wrestlers involved in the tournament.
The scene moves the next day. At Nightwing and Batgirl's headquarters, they got to the rooftop and looked at the beautiful sunrise. 
"Sun shines brighter in Gotham these days, doesn't it?", Nightwing asked. 
"Indeed.", Batgirl agreed. "A lot has changed in this city through the years. Some for the better.", she continued. 
"By that statement, I guess we've done a pretty good job making Gotham a safer and better place.", Nightwing said. 
"I think so too. But there's one thing that remains.", Batgirl replied. Nightwing looked at her. 
"Criminality.", she continued. 
"Yes that is. But there will always be crime. We can't ever truly stop it. We can only keep it at bay. And that is our job.", Nightwing said. 
"And I wouldn't mind spending a lifetime fighting crime by your side.", Batgirl replied. 
They went back inside their headquarters and continued their conversation. 
"It's been so many years already since you've changed your identity. Why aren't you changing your vehicles' name yet?", 
"If it ain't broke don't fix it.", Nightwing answered. 
"Nice", Batgirl replied. 
"R-Cycle, R-Mobile, R-Plane, R-Marine, R-Ship. They all still sound cool anyways.", Nightwing said. 
"And Robin didn't?", Batgirl asked. 
"Now that I stepped outside Batman's shadow, I had to think of a new identity. One that would set me apart from him. For that reason, Nightwing is born.", Nightwing answered. "Have you ever thought of changing your name to something cooler?", he asked her. 
"If it ain't broke, don't fix it.", Batgirl answered. 
"Oh, you got me there.", Nightwing said, as they laughed. 
Nightwing and Batgirl were called on to the Batcave by Batman, Flash and Wonder Woman. 
"Nightwing and Batgirl. I'm back.", Batman announced. 
"After almost 2 years, finally.", Batgirl replied. 
"This calls for some celebration, I guess.", Nightwing said. 
"That can wait. For now, Wonder Woman, Flash, and I need you. A familiar gang in Gotham is on the loose. Not just an ordinary gang. A gang of metahumans.", Batman replied. 
"Oh, let's get going then.", Batgirl responded. 
Now, Nightwing and Batgirl headed to the Batcave immediately. 
"It's good to have you back, Bats", Nightwing said. 
"Good to see you both too.", Batman replied. 
"Who exactly are this gang of metahumans?", Batgirl asked. 
"It's the Iniquity Collective. A gang of futuristic villains. They've escaped from prison again.", Batman answered. 
"Them again? We've faced them before like a hundred times already.", Nightwing said. 
"And that's enough threat for the Justice League?", Batgirl added. 
"Do you think we'd come here if they weren't much of a threat?", Wonder Woman asked. 
"What have they done to warrant the League's attention?", Batgirl asked. 
"They're using futuristic weapons to terrorize people and we can't just let them run loose with those.", Batman answered. 
"Right now it's dangerous for us to let them loose while carrying these weapons. We must capture them as soon as possible.", Flash said. 
"Oh, now that's trouble.", Batgirl replied. 
"Let's get going now.", Wonder Woman told them. 
They monitored the Iniquity Collective's location through the Batcomputer and found out that they are doing crimes in Downtown Gotham. Now they went there and saw the villains. But, they were surrounded by their henchmen. They now fought their henchmen. The fight gave the villains time to escape. Later, they lost track of the villains. 
"Oh man, they got away.", Flash said. 
"Not too far away", Batman said. 
Using the GPS tracking device on his wrist, Batman led the heroes to the Iniquity Collective's hideout. They moved forward. 
They now went there and searched for the Iniquity Collective's hideout. While on the search, Nightwing and Batgirl had some questions. 
"Where did the Iniquity get the Apokoliptian tech weapons from?", Nightwing asked. 
"And where's Superman?", Batgirl also asked. 
"Superman's at Metropolis. He's got his own city to take care of.", Flash answered. 
"He's battling the Intergang forces out there. We're suspecting the Iniquity Collective acquired those tech from them.", Wonder Woman added. 
"Oh, so that explains it all.", Nightwing said. 
Now they got to the Iniquity's hideout. They saw some guards outside and they took all of those out. Now, they proceeded into the hideout. Then suddenly, the hideout's security was activated and infrared lasers blocked their way. Batman tried to hack into the security system, which he successfully did. They now proceeded, then later they got surrounded by robot drones. They destroyed all of those and now went to the main room of the villains. The villains were shocked. 
"Oh, so it's you heroes who hacked into our security", Shriek said.
"Look guys. Those tech you've stolen are dangerous. That makes you the Justice League's liability.", Wonder Woman told them.
"Now, hand them over before things get ugly.", Flash said.
"You heard them.", Batgirl seconded.
"Not a chance.", Parasite II said.
"I just hate it when the bad guys want to do things the hard way.", Nightwing said.
"Attack!", Inque commanded her gang.
Now, the heroes and the Iniquity Collective fought.
Inque attacked Batman and launched balls of lava at her. Batman groaned in pain. Now, Inque went on top of him and held his arms down the ground. Inque's touch started to feel like lava. It burned his sleeves.
"Looking haggard today, aren't we, Batman?", Inque said.
"You know, you can't be handsome all the time, at some time you reach a period of decline", Batman said. "Like you. Your hair looks shiny the last time we met, but now it looks frizzy in your return.", he calmly replied.
"You know, Batman, your style of flirting is unusual today. Anyway, you've wanted to fight, not to talk. So we're now giving you what you want", Inque said.
"That on your forehead. Its an Apokoliptian magmatic energy band. Taps its user's energy and converts it into lava.", Batman said.
"Oh, Batman. You are so smart to figure that out.", Inque replied.
"And it looks good on you.", he told her. "Mind if I take a look at it?", he asked, as he got off Inque's clutches and reached for her head, but she turned into liquid form and Batman was unable to get his hands on it.
"Nu-uh-uh.", Inque responded, as she took a few steps back.
Now, Nightwing and Batgirl took on Stalker, Wonder Woman on Shriek, and Flash on Parasite II.
Parasite pinned Flash to the ground and started absorbing his powers. Flash yelled in pain. Wonder Woman hits Parasite from behind to stop his absorption.
"Thanks. Damn. Every punch he threw felt like lava. And when he was absorbing my energy it felt like he's transferring lava to my body.", Flash said.
"Good thing Superman wasn't here.", Nightwing said.
Wonder Woman battled Parasite II, but Parasite knocks her down, went on top of her, and started absorbing her powers. She screamed in pain, as lava was being transferred to her body. 
"Good for us Superman's not around. Our job would be easier than I thought.", Parasite II said.
Flash took down Stalker quickly. 
"Its in Parasite's headband. That tech is from Apokolips. You hit it!", Flash told Nightwing and Batgirl. The two dodged Shriek's attacks and saved Wonder Woman. They attacked Parasite from behind. Then, Nightwing hit the headband with his metal pole, breaking it into two. He hit Parasite in the head so hard, he fell unconscious. 
"That's got to hurt.", Batgirl said. Then, she was shot down by Shriek's Apokoloptian sonic cannon.
"Batgirl!", Nightwing said.
"I'm fine.", Batgirl replied, as she rose up. 
Now, Nightwing and Batgirl battled Shriek. They later threw explosive Batarangs on him, knocking him down. They picked up the Apokoloptian tech the villains used: Parasite II's headband, Stalker's spear, and Shriek's sonic cannon.
Batman couldn't hit Inque with Batarangs because she keeps shapeshifting. She knocks Batman down, leaned on him and said, "If you had been mine this would've been easier".
Then Batman caught her in solid form, kicked her away and said, "I guess I wasn't that easy".
Batman now picked up his used his specifically designed brass knuckles to knock down Inque. 
"Lights out, Inque", Batman said, as he picked up the Apokoliptian headband from her head. Later, Nightwing and Batgirl tied all the villains with a Batrope. The S.T.A.R. Labs men came and froze the villains, where they'll be brought to the Cryogenics Lab.
"Inque didn't do a good job", Wonder Woman said.
"He sure didn't.", Batman said. 
"He sure also likes you.", Wonder Woman told him.
"I see that too. But I got no time for that.", Batman replied.
"Oh, I see. You're too busy to be making time for love.", Wonder Woman said. 
"I'm glad you know that.", Batman replied. 
"But have you ever considered committing to someone? Someone special? Will that time ever come?", Wonder Woman asked. 
"I haven't yet. But I hope so, Diana. Someday.", Batman answered. 
"Now that we're done with the baddies, can we now go on with the celebration, Bats?", Nightwing asked.
"Yes, we can. But we're not doing it at the cave.", Batman said. 
"Then where?", Batgirl asked.
He asked Martian Manhunter to teleport him, Nightwing, Batgirl, Flash, and Wonder Woman to the Watchtower. Later, they were transported there.
"Nightwing and Batgirl. Welcome to the Justice League.", Batman told them.
"Really? Please tell me this is just a dream.", Batgirl said, as she felt excited.
"All we ever wanted was to be part of the League. Now, its become a reality.", Nightwing said.
"You're officially one of us now.", Wonder Woman said.
"So, what can you say about our place?", Flash asked.
"We thank you", Nightwing and Batgirl said.
"It's beautiful.", Batgirl answered.
"Let us take you to a tour around the tower, shall we?", Flash asked.
"Our pleasure.", Nightwing replied.
