-Earth 616-

New York City

Hulk, She-Hulk, Thor, Doc Samson and Iron Man are fighting against the U-Foes in the middle of a decimated city street. Thor summons and fires a bolt of lightning at X-Ray, distorting his physical form and temporarily making him dissipate.

Hulk and Doc trade blows with Ironclad, who shrugs off Doc's inferior punches, though Hulk's hits have more impressive results, staggering the steel skinned behemoth. "Hulk smash ugly metal man!" Hulk roars as he punches Ironclad relentlessly like an enraged animal, Ironclad grunting in pain with each punch that connects with his face and body.

She-Hulk contends with Vapor, who is immune to the gamma powered vixen due to her body being composed of various gases. "Give me a kiss, beautiful..." Vapor seductively says as she entraps She-Hulk with her gaseous form.

"No thanks. Psychotic bitches aren't my type." She-Hulk retorts as Iron Man fires a repulsor ray at Vapor's head, making her disappear and freeing She-Hulk. "Thanks." She says, receiving a nod from Iron Man as a response to her gratitude.

Suddenly, Vector attacks Iron Man by flinging large pieces of concrete at the armored superhero, who fires repulsor rays and mini rockets to counteract the villain's attack.

Hulk punches both sides of Ironclad's head, stunning him long enough for him to grab him by the head and throw him at Vector, practically crushing him with his heavy body.

X-Ray attacks Thor again, but the Asgardian was ready for him. He flung his hammer at his foe, knocking him against a building as it returned to him. Before X-Ray could recover, Thor charged a massive lightning bolt from his hammer before unleashing it on his foe, overcharging him and making him explode.

All that remained was Vapor, who currently was avoiding Hulk and Doc Samson's attacks. Thor grinned as he and Iron Man prepared an attack. Thor spun Mjölnir around and around, dissipating Vapor as Hulk performed a loud thunderclap, causing Vapor to become solid.

"Now, Stark!" Thor hollered out.

Without wasting a second, Iron Man primed his unibeam and fired it directly at Vapor, completely vaporizing her as she let out one last scream of agonizing pain.

"No!" Ironclad yells as he gets off of the crippled Vector. He charges at Iron Man, tearing him out of his suit with his bare hands. Before he could crush him under his foot, Hulk punches him square in the face with a right swing. Before he could recover, Thor primed another blast of lightning, which, when released, surged throughout Ironclad's metallic body. He suddenly fell backwards onto the ground, seemingly dead.

"That's the end of the U-Foes..." Tony retorted before realizing that Vector was still alive, albeit in an immense amount of pain.

"This isn't over, Avengers. I will...have my revenge!" Vector yells defiantly.

"Oh, shut up, you egomaniacal dumbass!" Hulk retorts.

"Aye. We have bested you, yet you continue to mock us. You are beyond delusional, Vector." Thor says with a teasing grin.

Suddenly, a portal appears behind the heroes, sucking Hulk, Doc Samson, Thor and She-Hulk into it.

"No!" Tony yells out as the portal closes before he can do anything.

-Alternate Earth-

Gotham City

The heroes fall through the portal's other side, landing in a destroyed Gotham City, which is in a state of disarray as a massive creature is currently attacking its people.

"How'd we end up here?" Thor asks.

"W-Where are we?" She-Hulk asks as she inspects their new environment.

"No idea, Jen. But I don't like it. Not one bit." Samson says glumly.

The heroes then notice the monster attacking the civilians. "What the hell is that...thing?" Samson asks.

"No clue, but it's attacking those people, so I'm just gonna assume it's not here to make friends." She-Hulk says.

The monster, Doomsday, looks in the general direction of the newly arrived heroes and roars at them loudly before charging, knocking several cars out of his way.

"Finally. A real challenge!" Hulk says with delight as he cracks his knuckles before charging towards Doomsday, his fist connecting with Doomsday's face, sending him flying through several buildings. "Hmm. That was too easy." Hulk said with a smirk.

She-Hulk rolls her eyes before facepalming. "You did NOT just say that!" Right on cue, Doomsday emerged from the damaged building with barely a mark on him as he repositioned his broken jaw.

"You're strong. I'm gonna enjoy this." Doomsday says with a growly voice as he charges once again.

"Oh, boy..." Hulk mumbles as he charges, only to be tackled by his opponent, who beats him relentlessly, green blood splattering on his spiked fists. Thor intervenes, swinging his hammer hard against Doomsday, sending him flying across the street, hitting the ground several times before finally stopping and standing up. Thor attacked again, firing a massive surge of lighting at Doomsday before flinging Mjölnir directly at his face.

Hulk recovers from his horrific beating, holding Doomsday down and savagely pummeling him into the ground again and again, barely giving Doomsday time to react to him.

"Jeez..." She-Hulk mumbles as she watches Hulk unleash his rage onto his opponent.

Thor swings his hammer as he summons an immense amount of thunder into his hammer. Hulk leaps away from the beaten Doomsday right as the thunder is unleashed onto him.

When the smoke clears, Doomsday is barely moving, but his labored breathing is audible.

"Ugh! Just die already!" Hulk exclaims as he grabs Doomsday by the ankle and flings him into space. "Hulk is strongest there is!" Hulk roars in victory.

"Well, that's debatable..." Thor mumbles to himself as a man in a black suit and cape approached them. On the chestplate of his armor was a bat-like symbol.

"Who the hell are you people?" The man asks as he looks at the heroes.

"We could ask you the same thing." She-Hulk says in answer.

The man scowls before sighing. "The formalities will have to wait. Because we have a problem...and you four might be just the answer we need."

"Who's 'we'?" Hulk asks, crossing his arms in front of his chest.

The man simply looks at Hulk. "The Insurgency."
