An hour before the battle in D.C., Arthur prepared himself to leave for the glowing shipwreck. Mera stopped him and said, "Hold on just a minute! Do you even have a plan?" and Arthur answered, "Yes. I'm going to go into the shipwreck, get a piece of the Belt of Power, and come back." he smiled after he said that while Mera shook her head. Now, Aquaman at this point still didn't know that all three pieces of the Belt were already revealed on the surface world; so he's going after something that's not even there. Mera told him, "Be careful." and the two shared a little kiss before Aquaman left for the shipwreck.
Forty-five minutes before the battle, Aquaman arrived at the shipwreck and sent in a pair of sailfish into the shipwreck to survey it. The ship began to rumble and he heard the noises of what sounded like a deep sea monster getting his dinner. Aquaman continued closer to the core of the ship and the rumbles grew louder and stronger.
Thirty minutes before the battle, Aquaman proceeded with caution when he saw a pair of red eyes looking right back at him. The unidentified monster or Leviathan let out a thunderous roar and attacked the King of Atlantis. Aquaman attempted to control the beast but he wouldn't succumb. Aquaman swam around in the ship, summoning salmon to block the monster's vision and sharks to knock him out. The beast shook off the salmon and tore threw the sharks before he chomped on Aquaman. Aquaman, within the mouth of the Leviathan, struggled to keep his mouth open and avoid being dinner. At that moment, a wave current blew back the monster and set Aquaman free from his clutches. Mera was responsible and she said, "I had a feeling you'd need help." and she continued to lay into Leviathan with her wave attack. Aquaman took this opportunity to lay a grand slam attack on the head with his trident to defeat the giant beast. Once this was done, Aquaman said to Mera, "While I appreciated your help, I had this." Mera asked him, "Why weren't you able to control this creature?" "It's one of two things. Either the creature didn't come from the sea to begin with, or the sea creature was already under the influence of something or someone else. If it's the latter, it must've had a strong influence to resist my control." They both examined the monster and it was like a hybrid between a shark and an octopus.
Fifteen minutes before the battle, the monster began making rumbling noises again. Aquaman and Mera prepared themselves again but it turns out that Leviathan spat out a small glowing orb and said, "Ugh, thank God that thing's out." Both Aquaman and Mera were astonished to see the creature speak and Aquaman asked Leviathan what his name was. Leviathan answered "Lusca, I believe. Holy sh*t, my head feels like it's splitting into two right now." Mera asked Lusca, "Where are you from or where did you come from?" and he answered, "I don't know, honestly. All I remember is having this blue thing shoved down into my throat, being in a lab, and then getting thrown into the ocean. However, what I do remember is that this orb is supposed to be attached to that there trident that you have." Aquaman was now confused, "How and why does this 'orb' attach to my trident? Speak." Lusca said, "You know about how the Amazons had original possession of the Belt of Power?" Aquaman nodded while Lusca continued, "Well, the Atlanteans are in possession of the antithesis to that and that's what this orb is. It's called th-the... um. Shoot, I can't remember the name because of this damn headache." Aquaman came to a realization and said, "Wait, this is the Orb of Depowerment." and Lusca exclaimed "YES! That's the name!" Mera finally realized this as well. Aquaman took the orb and it attached itself to the center of the trident and the trident changed to a blue tint of color in a blinding flash of light. Lusca then said, "You can shoot a lightning bolt at a piece of the Belt or the whole thing to depower it. However, the effect is very temporary and it's only meant to be used to get the Belt of Power away from a malevolent user." Mera suggested to Aquaman, "We can tell Batman about this new development and stop this once and for all." Aquaman agreed and the pair held hands as they swam back to Atlantis, thanking Lusca.
The battle between the Justice League and Lex Luthor and Sinestro began. Aquaman tried to communicate with Batman but he's already busy in the fight, he tried calling Wonder Woman but she's also busy in the fight. He then attempted to contact the Flash.
