== Plot ==
Nightwing, Batgirl, Wonder Woman, and Steve Trevor found trouble at Midtown Gateway City, where they found Queen Bee and Dr. Cyber taking down police who were trying to stop them. They asked the police what did they do, and they told them that the two villains stole military weapons at an abandoned weapons factory. "Oh, that's enough to raise our concerns", Wonder Woman replied. The heroes were about to charged at them, when suddenly they called their henchmen and surrounded the heroes. Now, the heroes started battling the henchmen. The police backed them up. Later, they were able to take down their henchmen. Nightwing and Batgirl took out Queen Bee, while Wonder Woman beaten Dr. Cyber. Now, the police arrested the two villains and had the stolen military weapons returned to its rightful places. Wonder Woman and Steve Trevor thanked Nightwing and Batgirl for the team up as they now went away. The scene moves to the oceans, where Scavenger was seen, leading an Atlantean tribe named the Trench. They approached nearer and nearer to Atlantis, until Nuidis Vulko, who was on guard along with the Atlantean army, later took notice. They immediately reported to Aquaman. 
"King! There are intruders incoming. It's one man leading an army.", Vulko told Aquaman and Mera at the palace.
"Probably one of Black Manta's lackeys again", Aquaman said.
"What? The Black Manta?", Vulko asked. 
"Oh, I haven't told you about it yet.", Aquaman answered, as he told Vulko and the army to come forth.
"Listen, my army. Atlantis is threatened by a series of attacks organized by none other than the Black Manta. This is the reason why I tell you to do rounds at Atlantis ever since Charybdis' attack. We can't let our guard down. If we do, then the Manta will take advantage and it will lead to our downfall. So, I request you to hold ground on our kingdom's vicinity, and be ready when the enemy out there strikes. I will also call reinforcements.", Aquaman announced. 
Now, the Atlantean guards agreed, and Vulko led the army outside the palace and stay on patrol. Aquaman now called Nightwing and Batgirl, asking for their help. Nightwing and Batgirl went there immediately using the R-Marine. Moments later, they reached the kingdom of Atlantis. They were welcomed by the Atlanteans. Now, they asked Aquaman who this threat is. Aquaman doesn't know yet as well. Few moments later, they stood on patrol but no one came.
"Are you really sure there's a threat? Cause we've been waiting for hours already", Nightwing asked.
Later, they felt the sea floor quaking.
"They got you what you wanted now", batgirl told Nightwing.
"Oh no", Nightwing said.
From the sea floor, emerged Scavenger and the Trench. Nightwing, Batgirl, All the Atlanteans were shocked. Scavenger and the Trench were aggressive and took down some of the guards.
"What are they? They're quite stronger than Atlanteans", Nightwing asked Aquaman.
"Yes they are. They're the Trench. A lost tribe here in Atlantis. They live in the depths of the ocean and evolved through time", Aquaman answered.
"And who's their leader?", Nightwing followed.
"Oh no! It's the Scavenger! Peter Portimer, he's been quite a menace to me and a threat to my kingdom. He's dedicated to plundering treasures of the ocean, and that makes him a threat for all of us. Our kingdom is quite rich.", Aquaman answered.
"Oh no. We need to stop them immediately", Batgirl said, as her, Nightwing, Aquaman, and Mera now joined the battle.
Nightwing, Batgirl, Aquaman, Mera, Vulko, and the Atlanteans battled the Trench. However, the Trench are quite strong. They defeated most of the Atlantean soldiers. While the Trench kept the heroes busy, the Scavenger swum away from the battle and look for a way to get to the Atlantean vault, where a large amount of Atlantis' treasure was kept. Only later, Aquaman noticed that Scavenger wasn't around. He thought he already got away, so he immediately called Nightwing, Batgirl, and Mera to help him find Scavenger. He might be going for Atlantis' treasure vault, he told them. Nightwing and Batgirl rode the R-Marine to move and travel to reach Scavenger faster. Later, they found his trail. Nightwing and Batgirl noticed some remnants of artifacts floating. They told Aquaman and Mera that and now they continued moving and followed the trail. The trail led them to the Atlantean treasure vault. And it was very predictable. The vault was open, and they entered it. Nightwing and Batgirl went down the R-Marine and However, when they entered it, they were shocked that Scavenger was not there, and he has taken treasure, but not all that's in the vault. He left a little of Atlantis' treasure in the vault. However, they saw a large hole on the ground which Scavenger obviously bore. Nightwing, Batgirl, Aquaman, and Mera decided to split up. Nightwing and Batgirl went back to the R-Marine and maneuvered it, while Aquaman and Mera went down the burrows. Scavenger called his henchmen who were on a submarine, to pick him up. Meanwhile, Aqualad and Aquagirl just finished school when they saw a breaking news on a tv store, saying Peter Portimer, better known has Scavenger, is back on the loose. Now, Aqualad and Aquagirl hid from the crowd then now opened the portal to Atlantis using their powers, and entered it. On their way out the portal, they found a submarine which looked suspicious. So, they broke it open and took a look inside.
"Hey! Who are you two?", one of the men inside the submarine asked.
"We order you to stand down, and let us maneuver this submarine", Aqualad told them.
"Hey, who do you think you are to command us?", one replied at them.
"We just wanted to know who sent you here?", Aquagirl asked.
"None of your business", one answered, but another said, "We work for the Scavenger. While we are sent by Black Manta".
"You idiot! Why did you tell them?!", another man asked, frustrated.
"Well, we've heard enough.",Aqualad said.
Now, the henchmen attacked them but they took out all of the men inside the submarine. They went to the control room and maneuvered the submarine. Meanwhile, Aquaman and Mera, swimming through the burrows, heard beeping sounds from underneath. They realized Scavenger placed land mines on his trail. Mera and Aquaman swam their way out the burrows as fast as they can, before the land mines blow up, at the last minute. They were able to get out in time. They found Scavenger, and two of his henchmen carrying bags of stolen treasures. His submarine came and he told Aquaman, "Say goodbye to your treasures". When Scavenger was about to enter the submarine, suddenly he and his two henchmen were knocked down by Aqualad and Aquagirl who came out. 
"Aqualad! Aquagirl! What took you so long?", Nightwing said, delighted but a little pissed.
"We just came from school. We only found out when we got out. Why did nobody call us?", Aqualad asked.
"Cause we're all busy fighting, duh", Batgirl answered.
Aquaman told the other four to focus, as Scavenger is getting away with the treasure. The others were able to take down the henchmen and retrieved the two bags of treasure they were holding. Scavenger was able to get in the ship. But Aquaman called his whale ally, which bumped into the submarine and cut it in half. But Scavenger was persistent and still tried to swim away. But, Batgirl was able to swing her batrope and get him. Nightwing, Aquaman, and Aqualad helped her pull Scavenger near. Now, Aqualad took the treasure away from him. Now, Nightwing tied Scavenger and all his henchmen with the Batrope, and Aquaman and Aqualad got them into the R-Marine. While Aquagirl, Batgirl, and Mera brought all the stolen treasure to its rightful place at the Atlantean vault. To ensure no one ever breaks it open again, Mera changed the password combination of its lock. When the heroes returned near the palace, they saw the Atlantean guards triumph against the Trench, but many soldiers were wounded in the battle. Nuidis Vulko immediately reported Aquaman that the Trench have been forced to retreat when they have been outnumbered ,outbattled, and outsmarted. Aquaman commended and praised Nuidis Vulko and the Atlantean guard for being able to defend the center of Atlantis and told the wounded and bruised soldiers to take time to heal, even fight through it they must, because the battle is not yet over. Now, he told the guards to bring Scavenger and his men to prison, which they immediately did. Now, Aquaman and the heroes went to the palace to take a rest first. 
Meanwhile, at Black Manta's hideout, he saw Scavenger's failure from his monitor. Now, he called on Ocean Master.
"Orm, your time has come. This is now a golden chance for you to dethrone your brother and claim your place as ruler of Atlantis.", Black Manta told him.
"It would be my great pleasure to battle Aquaman by your orders", Ocean Master replied.
"Once we succeed, Atlantis will be ours!", Black Manta added. 
"I'm sure it will", Ocean Master said, as he made a sinister laugh.
From their palace, Aquaman asked his adviser, "Please tell all the guards of Atlantis to stay on patrol all over our city. We must never let our guard down, not even for the shortest bit. Let's stay like this until the greatest threat to our kingdom has subsided." His adviser did so and alerted all the Atlantean guards. Nightwing and Batgirl now said goodbye to the Aquaman family.
"So, that's our plan? We're just gonna sit here and wait?", Aqualad asked. 
"I believe will do better when we're on the defensive. We got the advantage here", Aquaman answered.
"I agree. Once we let our guard, that's when they'll strike.", Mera said. Aquagirl also agreed
"At least when we're on our kingdom, we'll be ready for anything", Aquaman said.
