Victor von Doom was born in a Romani camp outside Haasenstadt, Latveria. His mother, Cynthia, was killed in a bargain with Mephisto that went wrong. Despite his father's attempts to care for her, a noblewoman died and Werner von Doom fled with a young Victor on a cold winter's night. Victor survived the cold, but unfortunately his father did not. Doom sought to increase his knowledge of both science and magic in order to rescue his mother, whose death he blamed on Mephisto. In his youth, Victor fell in love with a woman named Valeria, but she resisted his advances.

The State University in Hegeman, New York offered Victor a scholarship. While attending classes there, he met Reed Richards and Ben Grimm for the first time. They developed a dislike for each other, leading to Reed Richards commiting the first prank he had ever pulled, changing Victor's last name on a trophy to "Doof."

Richards and Doom were intellectual peers. The two debated esoteric theories day and night that amazed faculty members, who compared their brilliance to that of Albert Einstein and Leonardo da Vinci. While Richards designed his starship, Doom became obsessed with developing a machine that could project the astral form of a being into other dimensions, seeing it as a way to free his mother's soul from Mephisto's clutches. Reed pointed out a flaw in Doom's calculations, but Doom arrogantly ignored his warnings, feeling Reed was trying to upstage him, likely due to their dislike for each other. The machine exploded, scarring Doom's face. He was soon expelled for conducting unethical experiments. From then on, he blamed Reed Richards for the destruction of his face as well as his expulsion.

Now here he was, sitting at a bar that was supposed to work as a base. Frustration radiated from his imposing figure as he tapped his fingers impatiently on the wooden counter. He had been waiting for Taskmaster, Crossbones, Electro, and Ghost to return from their mission. They had been sent to procure advanced gear and technology from a mysterious seller at the docks, but they were taking longer than expected.

Just as Doom was contemplating the consequences of their delay, the chilling presence of Red Skull approached him. Doom's eyes, concealed behind his iconic mask, narrowed as he regarded his unwelcome visitor.

"Red Skull," Doom uttered in a tone that matched his annoyance. "We've been here for far too long. The League of Villains, and even All for One, seem content to keep us waiting."

Red Skull's grim countenance reflected understanding mixed with frustration. "Doom, I agree. This situation is less than ideal. However, we find ourselves with limited options. Our goals align, and All for One possesses the resources we require."

Doom's voice grew colder as he responded, "I am not accustomed to waiting, Skull. All for One may possess power, but his methods and leadership leave much to be desired."

Red Skull nodded, acknowledging the valid concern. "We are villains, Doom. We thrive on chaos and personal ambitions. But in this world, where heroes and Quirks dominate, we must adapt. The League of Villains presents us with a chance to amass power and resources."

Doom's steely gaze studied Red Skull, weighing the gravity of his words. "Very well, Skull. We shall see how this alliance unfolds. But know this, I will not remain idle if our interests are compromised."

Red Skull extended a gloved hand, their palms meeting in a pact of necessity. "Agreed, Doom. We both understand the stakes. Our survival in this world depends on our ability to adapt and seize opportunities when they arise."

As their hands parted, Doom's posture relaxed slightly, acknowledging the practicality of their situation. "So be it, Red Skull. Let us wait for our comrades to return. Once they do, we shall discuss our next move."

The bar's door swung open, breaking the tense silence that enveloped Doctor Doom and Red Skull. Taskmaster, Crossbones, Electro, and Ghost walked in, their presence announcing their return. Taskmaster, his skull-like mask concealing any emotions, approached the bar with a nonchalant stride. The others took their places nearby, their faces reflecting exhaustion from their recent endeavors.

Doom's eyes glanced over the returning villains, assessing their progress with a mixture of impatience and curiosity. He turned his attention to Taskmaster and spoke with an edge in his voice. "Took you long enough. Report."

Taskmaster leaned against the bar, unflinching under Doom's piercing gaze. "We encountered a minor setback during the deal. Naturally, we resolved the situation, and we obtained the desired gear."

Doom's expression remained inscrutable, his displeasure barely contained. "Ensure that such incidents do not repeat, Taskmaster. We cannot afford any more complications."

Crossbones interjected, his gruff voice laced with annoyance. "Don't worry, Doom. Stinger won't be a problem anymore. We made sure of it."

Doom nodded, seemingly satisfied with their resolution. "Very well. Show me what you've acquired."

Taskmaster reached into a nearby duffel bag and revealed an assortment of advanced weaponry and gadgets. His gloved hands displayed an impressive array of firearms, energy-based devices, and intricate gear designed to enhance their abilities.

Electro, with electricity coursing through his veins, leaned closer to the table. "These gadgets are a game-changer, Doom. With these, our powers will be even deadlier."

Ghost, his voice barely audible, added, "And the stealth tech we obtained will grant us unparalleled advantage in infiltrations and covert operations."

Kurogiri, the living mist and loyal lieutenant of the League of Villains, materialized near the bar. "Impressive acquisitions, indeed. These resources will undoubtedly aid us in our quest for dominance."

Doom acknowledged Kurogiri's presence with a nod. "Indeed, Kurogiri. Your assistance in coordinating these operations has been invaluable."

As the atmosphere in the bar seemed to ease slightly, Taskmaster took the opportunity to inquire about two prominent figures who were notably absent from their midst. "Kurogiri," he began, "where are Whiplash and Green Goblin? I expected them to be here."

Kurogiri, his dark mist swirling with a hint of mystery, replied, "All for One dispatched them on a personal assignment. He deemed their unique skills necessary for a covert operation that requires utmost secrecy."

Crossbones leaned forward, a glint of curiosity in his eyes. "Personal assignment? What's All for One up to? He's always playing his cards close to his chest."

Kurogiri's reply was cryptic, as was often the case with the enigmatic villain. "All for One's ambitions are vast, and his plans extend beyond our current scope. We must trust that he knows what he's doing."

Taskmaster nodded, understanding that questioning All for One's decisions was unwise. He turned to Ghost, who had raised a crucial concern. "Kurogiri, what about Tomura Shigaraki? Is he not going to join us?"

Kurogiri hesitated, knowing that Tomura held great significance for them. "Tomura Shigaraki is on a separate path for now. He has important matters to attend to that require his singular focus. Rest assured, when the time is right, he will rejoin our cause."

Ghost's translucent form shifted uneasily. "I hope he's not getting in over his head. Tomura is a valuable asset to us."

"Indeed," Kurogiri acknowledged, "but he has proven himself capable. All for One has entrusted him with critical responsibilities."

Red Skull interjected with a sardonic smile, "Ah, the complexities of leadership. Every leader has their favored ones, but remember, loyalty can be a double-edged sword."

Kurogiri, agreed with a nod. "True words, Red Skull."

Doctor Doom looked at Taskmaster. "Did Tinkerer have what I was wanting?"

Taskmaster handed him two peculiar vials—one glowing yellow, the other blue. The intensity of their radiance hinted at their significance.

Taskmaster shifted his weight, glancing at the vials he had retrieved from the seller known as Stinger. "These are the items that Stinger was most eager to part with," he explained. "He seemed rather relieved to have them off his hands."

Doom's analytical mind worked swiftly, considering the possibilities of the vials' contents. "And did Stinger reveal what these vials contain?"

Crossbones interjected, a smirk playing on his lips. "He didn't provide specifics, but he did mention they hold unique powers, powerful enough to sway the tide of any battle."

Electro's curiosity got the better of him, and he leaned in to get a closer look at the vials. "They're emitting such energy. I can feel it coursing through the glass," he remarked.

Ghost, always cautious, couldn't help but voice his concern. "Be careful, Taskmaster. Powerful artifacts like these often come with unforeseen consequences."

Taskmaster acknowledged Ghost's warning with a nod. "Indeed, we need to exercise caution. But if these vials truly possess such power, they could be formidable assets in our conquest."

Kurogiri, observing the exchange, chimed in, "Doctor Doom, your knowledge of mystic arts and technology may help us discern the true nature of these vials."

Doom took the vials from Taskmaster's hand and held them up to the dim light of the bar. His keen intellect began to assess the vials' properties. "The energy emanating from them is unlike anything I have encountered before," he mused. "It's as if they harness cosmic forces."

Within the hallowed halls of UA High School, Captain America, also known as Steve Rogers, sat down with Tony Stark, the brilliant inventor and hero Iron Man, to discuss plans for combat training. Steve was determined to push the students of Class 1-A to their limits and help them learn the value of teamwork.

"So, Steve, what's the plan for their training?" Tony asked, sipping on a cup of coffee.

Steve leaned forward, his shield resting against the table. "I've been thinking about this since I talked with Rei the other day. I want to see them working as a team, facing challenges together."

Tony raised an eyebrow, intrigued by Steve's idea. "And how do you plan on achieving that?"

A smile crossed Steve's face. "I've decided to put them all in one team and have them face some real challenges. I want to test their abilities and how well they can cooperate."

Tony chuckled. "You always have a flair for dramatics, don't you, Cap? Alright, who will they be facing?"

Steve leaned back in his chair, crossing his arms. "You, me, Thor, Scott, and Rhodey. We'll show them what it's like to go up against a team of experienced heroes."

Tony's eyes lit up with excitement. "That's quite the lineup. But what about Peter and Bruce?"

Steve sighed, considering the implications. "I don't think it's wise to have the class face the Hulk. And Peter is in the same class as 1-A; he's already familiar with them. I think it's better if he works with his classmates. Besides, he's got enough on his plate juggling school and being a long way from home."

Tony nodded in agreement. "Fair enough. I can see the logic in that."

- - -

Excitement rippled through Class 1-A as they donned their hero costumes, eager to showcase their newfound abilities. All Might, the Symbol of Peace, stood before them, his towering presence radiating encouragement and confidence.

"Today, you'll have your first taste of combat training in your hero costumes," All Might boomed with his signature smile. "This training will help you understand the importance of cooperation and teamwork in facing real challenges."

The students listened attentively, feeling a mix of nerves and determination. They knew this was a crucial step in their journey to becoming true heroes.

At Grounds B, the familiar training area, the students gathered in a circle, their hero costumes representing their aspirations and uniqueness. The air was charged with anticipation as they awaited further instructions.

All Might clapped his hands together. "For today's training, you will face a team of experienced heroes. They will challenge you, but remember, this is not about winning or losing. It's about learning, growing, and discovering the potential within you."

Suddenly, Captain America, Iron Man, Thor, Ant-Man (Scott Lang), and War Machine (Rhodey) emerged from the sidelines, ready to take on the students.

"Wait? Are we fighting our homeroom teacher?" Uraraka asked as she put a finger to her lip.

Captain America stepped forward, his commanding presence filling the training ground. The students of Class 1-A gathered around him, their hero costumes representing their aspirations and determination.

"Listen up, everyone," Steve addressed the eager young heroes. "Today's combat test will be a simulation of a high-stakes scenario. My team and I will play the role of the villains, while all of you will be the heroes tasked with stopping us."

The students' eyes widened with anticipation as they processed the challenge ahead.

"Our objective is to guard a simulated 'nuclear weapon,'" Steve continued, his serious demeanor conveying the gravity of the situation. "Your mission is to prevent us from deploying it. You have a limited time to either capture us, reach the nuclear core, or find a way to neutralize the threat."

Murmurs of excitement and determination buzzed among the students. This was the real deal—a chance to prove themselves and showcase their hero potential.

"Remember," Steve emphasized, "this is not just about winning or losing. It's about testing your skills, teamwork, and quick thinking. Safety protocols are in place, and the bomb isn't real, but the situation will feel real."

With adrenaline pumping through their veins, the students spread out across the training ground, ready for the test to begin. The battle-hardened team of Captain America—Tony Stark as Iron Man, Thor, Scott Lang as Ant-Man, and Rhodey as War Machine—assumed their roles as the formidable villains.

- - -

Captain America's team arrived at their secure base, hidden away from prying eyes. Inside the dimly lit command center, they gathered around a large holographic display to discuss their strategy for guarding the simulated "nuclear bomb."

Captain America took charge, his leadership skills evident as he outlined their plan. "Alright, here's how we'll handle this. Three of us will patrol the perimeter, keeping an eye out for any of the students. The other two will stay behind and guard the bomb."

Thor, with Mjolnir resting by his side, stepped forward, his booming voice filling the room. "I shall accompany the whoever stays, Captain. No villain shall pass while I still stand."

Captain America nodded appreciatively, knowing that Thor's strength and lightning would be invaluable in protecting the bomb. He then turned to Tony Stark, alias Iron Man, who stood by his side, ready for action.

"Tony, I need you to stay with Thor. Your versatility and tech will be essential in case things get rough," Cap said.

Tony smirked behind his helmet. "You got it, Cap. No one touches the bomb on my watch."

With their roles assigned, Scott Lang and Rhodey exchanged glances. Rhodey spoke up, "We'll take the patrol duties, with you. I can fly overhead while you and Scott stay on the ground."

Scott grinned, already shrinking in size to fit on top of an ant. "Sounds like a plan. I'll keep my eyes peeled and be ready to grow when needed."

Captain America was satisfied with the division of tasks. "Remember, everyone, this isn't just about stopping the students; it's about testing them and helping them grow. We need to give them a fair chance while ensuring the safety of the simulation."

With their roles clear and their objectives set, the team dispersed to their respective positions. Thor, and Iron Man took their positions around the simulated bomb, their unwavering dedication to protecting it evident.

Outside the base, Rhodey soared through the sky while Scott and Captain America stealthily navigated the ground. They covered every angle, vigilant and alert for any signs of intrusion.

As the combat test commenced, the heroes of Class 1-A found themselves faced with the daunting task of infiltrating the base and neutralizing the simulated bomb guarded by Captain America's team. In the midst of the action, Tenya Iida stepped forward, his characteristic determination shining in his eyes.

"Everyone, gather!" Tenya called out, taking charge of the situation. The Class 1-A heroes quickly regrouped around him, their costumes reflecting a mix of excitement and focus.

"We must strategize and approach this situation with precision," Tenya declared, his voice resolute. "Captain America's team is highly skilled and experienced. To succeed, we need a plan that plays to our strengths."

The heroes nodded, acknowledging the importance of a well-executed strategy. They had trained together, learned each other's quirks, and developed a bond of trust.

"Iida's right," Izuku Midoriya chimed in, his analytical mind at work. "We need to work together, utilizing our individual abilities and coordinating our attacks. Captain America is a skilled fighter and we're unsure about what the others fighting strategy's are." Izuku continued.

Bakugo turned and walked away. "Kacchan! We need to formulate a plan that will-" Izuku said.

"Save your breath! I'll handle them on my own! I don't need anyone's help!" Bakugo yelled back at them and took off.

Yaoyorozu looked at Iida, "Forget it. We have 19 others here. We should be able to defeat them with all of our powers. We have the numbers game on our side."

Peter Parker finally spoke up. "I've had some experience with Captain America, Iron Man, Thor, War Machine, and Ant-Man. Let me give you some insights about their abilities and fighting styles."

The group looked at him as he explained them.

Captain America (Steve Rogers):
Superhuman Strength and Agility: Cap possesses incredible physical abilities, making him a formidable opponent in hand-to-hand combat.

Yaoyorozu nodded as she listened, her tactical mind already whirring with ideas. "I believe we should split into teams. One group can focus on distracting Cap's team and drawing their attention, while the other sneaks through undetected to reach the core."

Tenya's eyes lit up with enthusiasm. "That's a great idea, Yaoyorozu. We'll need to select team members with complementary Quirks to ensure a successful diversion."
