Upon arriving, the Dark Knights and the Earth's Mightiest Champion give the update on what's going on in the Injustice universe to Superman. The scene changes to where both Superman and Batman are checking the monitor screen regarding the current situations and planning on what to do next while Insurgent Batman just pacing around behind thinking of something. While this was happening, Shazam was watching Prime Superman.

"We need to get started," Superman states, "Innocent people are dying."

"We'll take the others, so you can focus on their Superman" Batman suggested.

"We'll do it together. It'll prevent more casualties. Then Superman."

"I still can't believe it's him! Well, not our Superman, but still" Shazam was saying in his head. He then walked up to them, "I'll handle Black Adam, but I might need some help with that."

The Prime heroes nodded in agreement until they saw the Image of Doomsday, one of Superman's worst and biggest enemies.

"Doomsday's going to be tricky"

"Collateral damage"

"I'll have to force that fight elsewhere…" Superman then turned to Insurgent Batman's attention, "Anything else?"

The Insurgent Batman was still in his thoughts until he walked up to him, "I realized that this isn't entirely accurate, but it's good to have you back," He then looked at Regime Shazam, "Same goes to you, Billy."

The both of them nodded.

Back at Gotham, Green Lantern's losing to Regime Sinestro while Yellow Lantern keeps swinging his yellow butcher knife at Cyborg as he keeps dodging it.

Cyborg manages to attack him with his gun while Regime Flash uses his speed to stop him but Yellow Lantern uses his energy power to break free.

Cyborg was going to shoot him again but Regime Killer Frost freezes his gun and was accompanied by Regime Solomon Grundy as they both try to attack him.

While Aquaman is battling Regime Hawkgirl, Regime Black Adam decides to use one of the cars as a weapon and swings around to attack Aquaman. Just as he was going to throw at him, someone manages to destroy the car as everyone stops to see Superman's arrival.

"That's enough, Black Adam!" Superman declared as he was heading towards the ground gently, "If Kahndaq exists here I suggest you go home."

Regime Black Adam refuses as he tries to attack him but gets punch away to the streets. Adam resort into tossing multiple cars at Superman (luckily the moving cars have no drivers in them). Once Superman finds an opening, he shoots him with his heat vision.

"You're weak, hero! Your world suffers for it!"

Regime Adam tries again but instead misses Superman and keeps getting hit by his laser eyes.

"There's no place for you here!"

Finally after some final attempts, Adam gives up throwing and decides to attack but instead he gets punched aside by Superman. He then quickly got up.

"Superman modeled his government after mine…. We allowed no insurrection."

"Then it's a good thing I'm not alone." Superman states with a confident smile.

"What are you babbl-?!"

That was when a red and white blur hit him away. Everyone from the Regime was shocked to see the young hero standing over Black Adam.

"Impossible!"

"Clearly because I'm standing right here." Shazam retorts with a smirk.

Shazam then grabs him by the shirt and throws him towards a building (luckily, the building was fully empty). However, Black Adam quickly returned and punched him in the gut and kicked his face.

"This time, you'll die permanently!" Black Adam declares, deciding to finish what he and Superman had started.

"We'll just see about that!"

Stage 5: Shazam (Regime) vs. Black Adam (Regime)

The hero tried to attack first, but the champion of Kahndaq blocked it and punched his face three times and shocked him with his powers. He was about to strike again when the Earth's mightiest mortal rolled out of the way and then uppercutted him in the jaw.

Shazam then did a 6-hit combo on his archenemy and kicked him in the stomach before striking him with lightning. However, Black Adam then blocked some of his attacks, grabbed his arm and twisted it before throwing him into the air and bashed him right back into the ground.

Adam was about to put his fist through the young hero who was on the ground, intending to kill him here and there, but Billy rolled out of the way again and struck him with a lightning bolt. He then tried to punch him but Black Adam blocked it and the two pushed each other away, getting ready to clash.

"Arrogant Boy!"

"I'll show you arrogant!"

The two of them clashed, with Shazam winning by punching Black Adam into the ground while sending him in a distance. Kahndaq's champion was about to get up when the Earth's champion punched him into the ground again before picking him up by the shirt and throwing him into the other side.

Black Adam then stroke him with a 10-hit combo and three lightning bolts before Shazam blocked one of his punches and gave him a 25-hit combo in return, defeating the former champion of the wizard.

"There can be only one Champion around here!" Shazam proclaimed with a smirk.

The young hero was about to get closer to him until he was shot from behind by Regime Cyborg.

"I'm sorry what happened back at the Fortress, kid," Regime Cyborg started, "But betraying Superman was a wrong move."

Shazam then got up and turned around to face his former friend, "So is destroying cities and invading other universes!" He then got hit by the winged fellow regime member, Hawkgirl.

"There are Superman's orders, kid" Regime Hawkgirl said, about to strike again until she got knocked out by the giant zombie.

"Grundy?! What are you doing?!" Regime Cyborg asked in anger before Grundy knocked him out as well.

"Grundy… Doing… Right… Thing" Solomon Grundy said.

That was when Black Adam got up and looked at the two, "You two will pay for your treachery!" He was about to come towards them when Superman arrived and punched him in the face.

"Your evil must end."

Black Adam then tried to fight one more time, but Superman froze him into place with his ice breath.

"That'll hold you long enough"

That was when a yellow-like spikeball crushed him. Everyone stopped what they were doing and saw what just happened.

"HA! Hahahahahaha!" Sinestro laughed as he continued to swing his weapon up and down, smashing the ground and making sure that Prime Superman was dead. He then floats down and looks at Yellow Lantern, "Not so super, was he?"

That was when he felt someone poking his shoulder from behind. Sinestro, realizing who it was, tried to punch him, but Superman grabbed his arm and took the yellow ring off his finger, making him powerless.

The Big Blue then looked at Yellow Lantern, "Here's your choice to do what's right… I would take it."

Yellow Lantern thought for a moment before willingly taking the yellow ring off and handing it to Superman, who smiled at him for making the right choice. He then looks at Shazam, "It's good to have you back, Billy"

The Earth's mightiest champion then smiled at him.
