Batman recieved an alert that the Belt Linen part of the Belt of Power was stolen and is on the loose traveling south. He researched who was the culprit responsible for this. The computer worked itself into the security cameras in the area and Batman finds that the person responsible is Deathstroke and a band of mercenaries. He noticed a weird glow on the camera and zooms in on it. He saw Deathstroke wearing the Belt Linen which meant that he's even more fearsome than he already was. Superman came into the computer room and asked Batman, "What's up?" "Deathstroke has a part of the Belt of Power and is currently on the run heading to down to Alexandria. I'm going to need your help to take down this guy with his increased power. I'll also call on Wonder Woman for help as well, just in case." Batman responded. "Hopefully, we won't need her help with this." "Agreed." and the pair left for Washington D.C. with Batman putting on his powered Augmentation Suit.
As Slade was on the run, he received a text from "Anonymous". The text read "Good. Now most likely you're going to have a part of the League after you. You know what to do if Superman is among them." and Slade looked at his glove which revealed a kryptonite gem embedded into it. Sure enough, Superman and Batman in the Batwing arrive. Slade yelled out "SQUAD FORMATION!" and the mercenaries loaded the plasma cannons and proceeded to fire upon the two. One of the shots got a critical hit on the Batwing and it began to fall. Superman held the plane and safely landed on the ground with Batman ejecting out of it. Supes looked closely at the manufacturer of the cannons and sees that it's from LexCorp. He used his heat vision to destroy the cannons and the mercenaries, stricken with fear, run away at the sight of him. "You guys aren't getting away." said Superman as he went after the runners. Deathstroke revealed himself and said, "I don't need them." as he walked towards Batman. "I see you're wearing another fancy suit. Won't make any difference to the outcome of this fight." Deathstroke continued. "We'll see about that." Batman replied. Deathstroke began with firing upon Batman but Bats put up a shield that richochetted the bullets. They began to enter a struggle punch-by-punch, kick-by-kick. Batman was getting pushed back and his armor began to get dented by Deathstroke's increased power. As Slade went in for a sword slash, Batman grabbed the sword tried to hit him with his own weapon but the Belt Linen's power was overpowering his suit's power. Superman, then, came back and blew Deathstroke back up against one of the convoy cars. Batman used this chance to immobilize Deathstroke using two batarangs that held him against the car. Deathstroke broke out of the batarangs. Superman went in to hold down Deathstroke but he used the glove and impaled Clark in the chest with the kryptonite. Supes yanked it out and was greatly weakened by the kryptonite. Deathstroke kicked Superman in the side and went for the impalement again but got stomped on by Wonder Woman. The battle was finally over. Diana lent a hand to Clark to pull him back up. "It's a good thing I came when I did." Diana said. "Yes, it was. Now that we have secured one of the pieces, we can lock it away in the Vault and nurse Superman back to health." Batman relayed. "Someone else *cough* *cough* is coming." Superman weakly said.
The three heroes looked up and found a helicopter coming in the distance and the two people occupying the vehicle were none other than Lex Luthor and Sinestro. They appeared to be in cahoots and Sinestro still had the ornamental piece of the Belt of Power. Lex Luthor announced from the helicopter, "It appears your strongest player is down, so just give us that piece of the Belt and we won't need to get ourselves into any unnecessary fighting!" Batman announced back, "That's not going to happen!" "Think about the situation you two are in right now. Superman is down and weakened, you have nobody else here to help you!" "That's where you're wrong, calling the Green Lantern, the Fla-" the helicopter shot a plasma blast at Batman before he could finish the call. Wonder Woman blocked the attack with her bracelets but she said, "I'm not sure if we're going to win this one by ourselves with Sinestro's increased power and Lex Luthor's gadget trickery." another voice called out and said "You don't have to." and both Hal Jordan and John Stewart as Green Lanterns came in to sucker punch Sinestro.
Lex Luthor's helicopter transformed into his infamous exosuit and was ready to confront the Justice League along with Sinestro. John Stewart asked, "What is this, Transformers?" and Batman, Wonder Woman, and both Green Lanterns prepared to do battle over the two pieces of the Belt of Power.
Around thirty minutes before the fight between the Justice League and the pair of villains, Aquaman was deep in combat with a sea monster within the shipwreck and he was fighting to not be consumed by the beast.
