IRON MAN: BROTHER DON'T CAUSE TROUBLE

Hey, everyone! You must be wondering what kind of story this is. Let me introduce myself first.

My name is Jhon Stark, the little brother of Tony Stark. Yes, that Tony Stark. Somehow, I was born in the Marvel Cinematic Universe and became Tony's younger brother—which is still mind-blowing to me.

But here's the thing: I don't remember everything from my past life. The only memory I have is about the Marvel story, and that too, only up to the events of Avengers: Endgame. As for who I was or what I did in my past life? I have no clue.

***

I was born three years before Howard Stark and Maria Stark died. I was just a toddler at their funeral, held in the arms of a young Tony Stark. Standing there, I couldn't help but wonder: Where the hell did this "younger brother" of Tony come from?

Of course, I didn't have the capacity—or the reason—to ask this question. I was just a baby, after all.

But something strange was clear to me from the start: I had an immense knowledge of physics and biology. You might think I must have been a scientist in my past life, but I don't remember or care. All I know is that, right now, my brain is as sharp as the man holding me—Tony Stark.

Growing up, I realized something surprising. Tony genuinely cared about me. In the movies, he always seemed like a self-centered genius, but as my brother, he was entirely different. From the time I was born, our parents were always busy with their own affairs. Tony, on the other hand, was the one constantly around, even bringing me into his lab while he worked on experiments.

I thought he'd treat me with a casual fondness, like in the movies, but he didn't. Instead, I felt a real brotherly love from him—a connection stronger than anything I had expected.

At our parents' funeral, the atmosphere was somber. I, being so young, didn't feel much, but I could see the pain on Tony's face. Though he seemed composed on the surface, I knew he was deeply hurt.

Beside him stood James Rhodes, his childhood friend. Behind them was Obadiah Stane, Tony's uncle. Several others were present too, including Nick Fury—yes, the future director of S.H.I.E.L.D.—and an older man I recognized as Hank Pym.

The funeral ended quickly, and everyone left to move on with their lives. Tony and I returned home with Obadiah, who, at this point, was playing the role of a caring uncle. Of course, I knew he would eventually show his true colors, but for now, there wasn't much I could do.

17 Years Later

Seventeen years passed since Howard and Maria Stark died. By now, Tony had become a household name in America. As for me? I had kept a low profile on purpose. While my intelligence was no secret to Tony, very few people outside our circle knew about my abilities.

When I was six years old, I gave Tony quite the shock. I could fix all the electronic appliances at home. It wasn't a big deal for me, but Tony was stunned into silence.

Tony wasn't surprised by my intelligence—after all, he had been a child prodigy himself—but my abilities at such a young age still amazed him. From that moment on, Tony decided that I didn't need formal schooling. Instead, I stayed home and worked on various experiments, honing my skills in private.

Not only that One day, while watching a Chinese movie with Tony, I asked him a curious question:

"Brother, do you think we can become like them? You know, moving mountains and rivers with sheer strength?"

Tony chuckled and replied, "Little guy, don't overthink it. That's all fiction. There's no magic in reality. Normal people can't do things like that."

I expected this answer, so I didn't argue. But in my mind, I silently resolved to push the boundaries of what was possible.

At the age of ten, after four years of research, I unveiled my first major invention: a strengthening potion.

I brought Tony into my small lab—a gift he had given me—and proudly showed him a small bottle filled with a shimmering silver liquid.

"Look, brother, can you guess what this is?" I asked.

Tony frowned and examined the bottle. "Alright, spill it. What is this? Did you buy it from some shady store? Is it poisonous? I've told you not to mess around with stuff like this!"

I stared at him, dumbfounded. "What do you think I am, a little kid?"

"Aren't you?" he quipped.

Ignoring him, I cut to the chase. "I didn't buy it. I made it. This is my creation, my four years of hard work. I call it the Strengthening Potion."

Tony blinked, stunned into silence. "Come again?"

I sighed. "It's a strengthening potion I developed. If you don't believe me, you can check my research notes."

Handing him the detailed documents, I waited as Tony carefully went through every page. By the time he finished, he looked at me in complete disbelief.

"You really made this?" he asked, still shocked.

"Yes, brother. And no one else knows about it except you," I reassured him.

Tony sighed in relief, though his mind was racing. He knew that if some government organisations . ever caught wind of this, they'd be knocking on our door in seconds.

"Alright, kid," he said with a grin. "You've officially outdone me this time."

This was just the beginning of my journey as Jhon Stark, the little brother of Tony Stark. Who knows what the future holds? One thing is for sure—life with Tony is never boring.
