Atlantis Has Fallen, Part 2

Season 4 finale of Nightwing & Batgirl.
== Plot ==
"No way! This can't really be happening", Aqualad said.
"He's redeveloped this city into his own vision. He also asked the soldiers to statues to honor of him.
"How many days have we been gone?", Batgirl wondered.
"Black Manta's taken over the kingdom now. It's over", Aquagirl said.
"Not quite yet.", Mera said.
"Yes. Not quite. They're still my soldiers", Aquaman said, pointing to the Atlantean guards rounding the kingdom. He tried calling them, and commanding them to let them out. However, the guards did not listen.
"Sorry, but we don't recognize your order. We only follow Black Manta's commands.", one of the guards said.
Later, some of Manta's soldiers approached them and stabbed and electrocuted them from behind with small trident stunners. They all fell down to unconsciousness.
Aquaman fell to the ground and said "It's over".
Manta's soldiers brought the heroes to the dungeon, and told Black Manta about them.
"Boss, they somehow managed to find their way back here. But it doesn't matter. We got them taken care off.", one of the soldiers told Manta.
"Well done, boys. Lock them up here in this dungeon. They shall all watch me rebuild this city as they crumble under the weight of their failures.", Manta said. 
Now, the soldiers did so and Manta now went to the palace's main hall. Ocean Master is seen strapped on a wall struggling to break free. Black Manta went near him and talked to him.
"You had one job, but you failed to finish it. I did not expect this from you. You betrayed me. I'm disappointed", Black Manta told Ocean Master.
"I'm a warrior, not a killer! Still, I was able to defeat him. I got the job done.", Ocean Master replied.
"No, you didn't. What I did to you now was just right. You deserve the same fate as your brother. Maybe even worse", Black Manta responded, as he activated the electrocution mechanism on the metal straps. Ocean Master screamed in agony. He was tortured by Black Manta. 
Outside the palace, Black Manta's men and the Atlantean guards, now under Black Manta's control, are now abusing their power. Advanced harpoon weapons are given by Manta's henchmen to the Atlantean guards who chose to follow him. They started monopolizing Atlantis' wealth. They have also funded Atlantis' research unit for technological advancement. They also forced regular Atlanteans to build columns and statues in honor of him. Black Manta sought to change Atlantis for the better, all while rubbing his victory in front of Aquaman. The whole Kingdom of Atlantis is now in despair. However, there are still some who rebelled and struggled against the Atlantean guards. They were Atlantis's last hope. However, it is revealed the Atlantean guards didn't want to do all of it. They were just forced by Black Manta, who placed a collar on their necks, which he can use to electrocute them if ever they decide to disobey his orders. 
Back at the dungeon, the heroes have ran out of hope. 
"It's over", Aquaman said, "Or is it?", he added, after thinking of an idea. 
He used his telepathy to call his sea creature allies. However, they are inside the dungeon, while the sea creatures are outside the palace, and his telepathic waves are unable to reach outside.
"It's not working", Aquaman said, as he went down on his knees. "It's over.", he continued. 
Nightwing and Batgirl used their gadgets, such as Batarangs and lasers, and even explosive nanochips on the prison bars, but none worked. 
"Ugh! Nothing's working", Nightwing said.
"What's these iron bars made of?", Batgirl said.
"Black Manta may have remodeled these dungeon cells.", Tula thought.
"I see. Seems like there really is no hope.", Aqualad said.
"Wait, I feel backup in coming", Aquaman told the others.
"Is this your fish friends?", Nightwing asked.
"Yes, it is", Aquaman answered. "It took a while for my telepathic waves to reach through the waters outside, but my ally sea creatures are able to receive it just in time." 
Later, they saw whales, octopuses, and schools of fish break down the dungeon's walls. The sea creatures now attacked the Atlantean guards in the dungeon. The whales and octopuses were able to break the prison, and the heroes now broke free. Later, they noticed something on the Atlantean guards' necks. 
"Hey, take a look at their collars", Nightwing told the others.
Aquaman asked one of the guards about it, "What are these collars for?".
The guard he asked answered, "We were forced to follow king Black Manta's orders. So, he put these things on our necks so that if ever we try to disobey him, he will activate our collars and electrocute us. Please, save us."
"Alright, hold still, everyone.", Aquaman told all the guards, as he told the other heroes to help him remove their collars. The others did so.
"I just ask one thing", Aquaman told the guards. "Never call Black Manta your king. He's not your king and he never will be!", he added.
"Yes, king", the guards answered. 
"I guess I'm back in charge", Aquaman said, looking at Mera. Mera smiled. 
The sea creatures at the dungeon underneath caused a little quake on the palace above, where Black Manta is, and he accidentally pulled down the lever of the electrocution control, which stopped Ocean Master's electrocution. Now, Ocean Master broke free. 
"No way!", Black Manta said.
"Oh, yes!", Ocean Master replied, punching Manta in the face. 
Now, Black Manta picked up the trident of Poseidon, and fought back. He hit Ocean Master several times and knocked him down.
"You'll never prevail, traitor!", Black Manta said, pointing the trident at him. But from the palace's grounds emerged the heroes, and Atlantean guards, who were riding sea creatures. 
Now, Aquaman commanded his guards and Nuidis Vulko to go outside and stop Manta's men.
"My guards! They dare disobey the king!", Black Manta said, as he pressed the button that activates the EMP collars, which electrocuted the Atlantean guards outside the palace. Aquaman's guards saw it, and they removed the collars stuck on the other Atlantean guards. Now, they told the Atlantean civilians to get somewhere safe, while they handle the Manta men. The Atlantean rescue teams led the civilians somewhere safe. Back at the king's palace...
"Hello there, my old enemy. Shall we run it back?", Aquaman challenged.
"It would be an honor to be challenged by the former king of Atlantis!", Black Manta said.
Nightwing threw a Batarang which knocked the EMP collar remote off Black Manta's hand. Ocean Master was quick to crush the remote underfoot, which put all the Atlantean guards and scientists under Black Manta's electrocution control(Black Manta's also taken control of the Atlantean scientists). Now, the scientists used their weapons to battle the Manta men who were watching over them. 
"Now, your joy buzzer is gone. Let's see what gimmicks you have left in store", Aqualad told Black Manta.
"You really wanna find out? You all soon will. In the meantime I want to get it on with your king. Call your brother if you must.", Black Manta said, accepting Aquaman's challenge.
"You want to bring my brother in our battle as well? You are so gonna regret this", Aquaman replied. Now, Ocean Master stood up and he and Aquaman battled Black Manta. Mera and the others battled the Manta Men. The brothers were able to knock Black Manta down.
"Brothers?", Aquaman asked Ocean Master, reaching out his hand to him. "Brothers", Ocean Master accepted. 
Black Manta rose up and fought back. Later, he was able to knock the both of them down. While on the ground, he was about to stab Aquaman, who rolled away. Aquaman rose up and kicked Manta in the face. However, Black Manta, with the power of Poseidon's trident, was too much for them to handle. But later, while battling the Manta men, Mera stumbled upon the trident. And Mera realized it was the trident that Ocean Master used to defeat Aquaman. It is the Trident of Oblivion! She picked it up and used it to knock down the Manta men that attacked her. Then, she called Aquaman and handed it to her. Aquaman was able to catch it. Aqualad was also able to hand Ocean Master his trident.
"Now, we're even", Ocean Master said, as he and Aquaman pointed tridents at Black Manta. 
"You really think you can stop me? Now, that I'm king? It's too late now for your valiant efforts, but I admire your spirits", Ocean Master replied.
"Let's see", Aquaman said.
Now, the brothers continued their battle against Black Manta. At first, Black Manta got the upper hand, knocking both of them down, but later, Black Manta was getting beaten. He started feeling the strength of the Trident of Oblivion Aquaman wields. He was getting solid hits, and getting electrocuted.
"Seems like your memory has failed you this time. This was the same weapon you designed to help Orm take me down", Aquaman told Manta. 
"Like my brother, you underestimated the power of the Trident of Oblivion", Ocean Master said, as he kept swinging his trident at Black Manta. 
Later, after taking a lot of hits, Black Manta fell on the ground. Aquaman pointed the Trident of Oblivion at Black Manta's throat. The other heroes were now also able to defeat the Manta men. The Atlantean guards were now also able to prevail against the Manta men.
"Come on, do it! Finish me!", Black Manta told Aquaman, begging him to kill him.
"I won't. I'm going to do worse. You got to experience the same suffering you put my people on.", Aquaman answered.
"Very well then, Aquaman. You won once again.", Black Manta told him.
"You're lucky you're on the right end of my mercy today", Aquaman replied.
Now, Aquaman ordered his guards to send Black Manta and all his men to prison.
The next day, everyone in Atlantis returned, for Aquaman has returned to his rightful place, at the throne of Atlantis. He spoke in front of thousands of Atlanteans, with Mera and Ocean Master by his side, outside the palace.
"To all my fellow Atlanteans. It is with my sincerest apologies that I take full responsibility for all the damages caused by our war against Black Manta. We swear to prevent any of these events from happening again.", he said.
"You don't have to be sorry, king. It is your natural response to an attack on our kingdom. Naturally, in a war, there will be chaos. There will be destruction. But one thing is for certain. You did your responsibility. You did it all for your people", Nightwing, from the crowd, replied. 
All the Atlanteans from the crowd agreed, and all cheered in unison, "Long live the King!"
"I guess you are right, Nightwing. I thank all my people, for the trust they put in me. For never losing hope in me. If not for all of you, I would have given up kingship by now, but here I am, still standing in front of you. Still the king!", Aquaman responded, as he and Mera bowed to the crowd's cheers.
"With my return to the throne, I would like to introduce to my people, my new right hand, my brother Orm!", Aquaman announced, as he pulled and raised Orm's hand. Orm thanked all the people for welcoming him as part of the royalty. 
"Brother, I thank you.", Ocean Master told Aquaman as they embraced, then he followed, "But I don't think deserve this."
"After all that we've been through, you deserve all of this. After all, you're still my brother.", Aquaman replied.
"I thank you for everything, brother", Ocean Master said.
Mera hugged her husband Aquaman and said, "Long live the king!".
"And to the queen", Aquaman replied, as they shared a kiss.
Aquagirl pulled Aqualad close to her and they shared a kiss as well.
"What was that for?", Aqualad asked. 
"I guess you deserved it as well", Aquagirl answered, as she blushed. The two hugged each other.
"Guess we can call it a happy ending now", Batgirl told Nightwing, as the two hugged and shared a kiss. The episode ends with the Atlantis cheering "Long live the king!" several times.
