Thor swung his hammer and flew toward an attacking monster, bashing it in the head. "Begone, foul demon of Muspelheim!" Doctor Bruce Banner observed his fiery surroundings. "Thor, where are we!?" The God of Thunder obliterated two more of his adversaries. "Surtur must have lured me here to rid Midgard of its greatest protector!" Banner seemed even more confused, if that was possible. "Who is Surtur?" "He's brought me here so he can begin Ragnarök, unopposed!" Bruce sighed. "R... Ragna... you know what, I'll just let you fight these bad guys and get me back to New York." "There is no returning to New York, good Doctor! You must help me snuff the terrible ambitions of Surtur and his Fire Demons!" "And how am I supposed to do that? I joined the Avengers to use my brain. I don't wanna Hulk out again!" Thor flung Mjølnir at a Fire Demon approaching Banner from behind. The hammer flew back to the hand of the Asgardian, and he used its momentum to knock back a horde of monsters. He looked back at the scientist, and to his horror saw two Fire Demons dragging him away. "NO!" The Asgardian prince flew toward the Demons, crushing them with his hammer, but they kept coming. Soon, he was overpowered. Amongst the battle calls, a distinct voice cried out: "Hulk, SMASH!" A giant green being burst out from inside a swarm of Fire Demons and started beating them down with his bare hands. "That's more like it," chuckled a relieved Thor, continuing to fight back the demons. The two Avengers worked in unison to survive the incoming hordes. "Show yourself, Surtur!" yelled Thor. "If you are so determined to be my undoing, look me in the eyes!" A heavy, dark voice rung out from behind the two. It could only be described as evil. Evil incarnate. "I am not Surtur. However, I shall certainly be your undoing."
"Vacated this realm!?" exclaimed Hawkeye. "What does that even mean!?" "Please, put away your weapons," said the exasperated man. "I have nothing to do with the plans of Lord Doom. I simply tend to his well-being." "Tell us where he went," demanded Stark. "I have already told you! Lord Doom is no longer in this mortal realm. He has taken it upon himself to challenge the forces of evil that may infringe upon the soul of his mother." Hawkeye cocked his head. "Can someone explain to me what this dude's talking about?" "I don't understand it either," agreed Black Widow. "Lord Doom has prepared for many years. I assure you, his theft of the Chain of Souls was entirely justified, and his affairs are not of concern to you." Iron Man took a step forward. "Yeah, his affairs are actually our only concern. If you don't tell us exactly where he is, then we'll have to force it out of you." The man looked downward and deeply frowned. "Lord Doom instructed me on how to deal with any meddlers that attempt to interrogate me. When his secrets are revealed, his wrath is truly terrible. I am sorry it had to come to this; I wished for our meeting to go peacefully, but you have left me with no choice." The man pressed a button on the arm of his chair that was previously covered by his hand. The three Avengers heard the sounds of metal clanking upstairs, and in an instant they were attacked by a swarm of Doombots.
"Duck!" yelled Hawkeye, instantly pulling back his arrow and firing it at one of the Doombots. It violently exploded on contact, showering everyone with shrapnel. Iron Man ignited his repulsors, shooting blasts of energy at the the robots. The old man simply reclined in his chair, for there was nothing he could possibly do about the situation at hand. "What's the plan, guys?" asked Agent Romanoff, attempting to shoot the Doombots down with her pistol. "They just keep coming." "Then we need to just keep fighting," replied Hawkeye, doing just that. "I'm getting hit, bad," shouted Tony Stark. "We need an escape plan." The old man finally spoke up. "I'm afraid to say there is no escaping from this situation. Lord Doom programmed these Doombots to smash any enemy they focus on." "Seems like I'm still alive," quipped Barton while he shot a flaming arrow at another adversary. "These are the creations of the 'smartest man alive'?" joined in Tony. "I could program a fire extinguisher to be more deadly." "Does anyone else notice that light?" asked Black Widow as she dismantled one of the bots with her bare hands. "I do, too," agreed Stark. "Any idea what it is?" As they conversed, the center of the room burst into flames. "How did that happen?" exclaimed Hawkeye. The fire spread across the antique rug and caused old bookshelves to begin falling down. Soon, the entire room was consumed. The intense blaze quickly retreated, and left behind an inexplicably damaged parlor. The shriveled metal of broken Doombots and the mercilessly burnt artifacts were all that remained. The three Avengers, along with the old man, were simply gone.
Black Widow awoke to find flames surrounding her. She jumped up, pulled out her gun, and looked around. "Where am I?" The others began to wake up, extremely disoriented, asking the same question. Then, the ground collapsed beneath them, and their surroundings turned to black. The land around them instantly rematerialized, with a few more people there. Thor and the Hulk were fighting off a horde of Fire Demons, and a figure towered over them. He was almost certainly ten feet tall, and his skin was a fiery shade of red. He wore an equally red cloak, and his disturbing voice called out to the entire realm. "I see I have all of 'Earth's Mightiest Heroes' gathered here! What an absolute honor, on your parts. It seems that I have inadvertently brought the servant of Victor Von Doom to my realm, as well. I have no need for his presence. Be gone!" The evil being pointed his spindly finger at the elderly man, and he burst into flames on the spot. The Avengers could do nothing but stare. "You must be wondering who I am. I am Mephisto, Lord of Hell. I have brought you here to make a bargain, as we seem to share an enemy. Of course, if you say no, you will suffer a much worse fate than Boris." Hawkeye prepared to speak, but Stark beat him to it. "What enemy could we possibly share with the Devil?" "Victor Von Doom! He has come to my realm to cheat me out of something which is rightfully mine, and I've obviously noticed your crusade against the man. So, I make a simple offer: help me defeat Von Doom, and I shall set you free." Stark couldn't stop Barton from speaking up this time. "This guy is the literal Devil. I, for one, don't want to make a deal with the Devil." At that moment, the Hulk attempted to attack Mephisto. He rushed at the Hell-lord and tried to punch his face, but Mephisto simply flicked off the monster. A huge crater was left where Hulk crashed down. The other Avengers took a moment to process this, exchanging knowing looks. They charged together, but were held back by a giant wall of flames. "You're all fools! You will regret this!" With that, the Mephisto reopened the ground beneath them and they fell.
A camouflage Jeep moved through the desert, running over sharp rocks and smooth sand. Tony Stark looked at the man sitting next to him. "What did I do? No one's talking to me." "We're all intimidated by you," replied the driving soldier. "After all, most of our weapons were made by you." "I don't make the weapons. I design them. There's a difference." The marine next to Stark spoke up. "Hey, can I take a picture with you?" Stark appeared to ponder the question, before answering, "No, you can't." Everyone was silent once again. A moment later, Stark began to laugh. "Of course you can!" The soldier smiled, and another pulled out a camera. Then, it happened. Shrapnel flew everywhere. A jumble of voices cried out, though Stark could only hear bits and pieces. "I can't get the door open!" "They're everywhere!" "Keep Mr. Stark safe!" And then, he blacked out.
When he opened his eyes, he was alone in a dark cave. There was a box of scraps to the side, and a table in front of him. It was covered in blueprints for a metal suit. He stared at them, trying to make sense of where he was. Then he noticed the glowing light in his chest. He blinked, and he was on top of the Stark Industries building. His body was weighed down from exhaustion, and he could hardly stand. A man in the metal suit from the blueprints menacingly stood in his path, and punched the billionaire. The impact sent Stark flying, and when he opened his eyes he had shifted location once again. He was now lying on the surface of a race track, with a packed crowd watching his every move. A man stood over him, wielding two electric whips. The man smiled, and raised his arm. Stark braced for electrocution, but before he felt anything he was back in the Jeep. "No," he said. "This can't be happening." "What do you mean, Mr. Stark?" asked the soldier in the passenger seat. "This isn't happening! I need to get out of here!" Stark threw open his door and jumped out of the moving car as it exploded.
Just kidding, keep going!
