I Arrived in a Superhero World and Became a Grizzled Old Man

When the male lead woke up, he found himself on the streets of New York. He also realized that he had become a homeless man.

He thought things couldn't get any worse. Then he discovered that he wasn't just homeless: he was also a decrepit old man over seventy, missing a leg. He was on the verge of a total breakdown.

Just as he was preparing to kill himself and start over, a battle between superheroes broke out on the streets of New York. That was when he learned he had transmigrated into a superhero world.

He had been ready to die, but suddenly felt it would be a shame to go just like that. Since he was already here, he decided to put off suicide and see what the superheroes were like.

Just as he gave up on the idea of killing himself, a red figure came hurtling straight toward him. Fortunately, it landed right beside him instead.

When the male lead got a good look, he realized the figure was Iron Man.

Curious and excited, he instinctively stepped forward and touched Iron Man's body. At once, a power that hadn't belonged to him entered his own body.

After this, the male lead learned that he had superpowers too. From then on, he could punch Hulk, kick Superman, and even give Thanos a couple of slaps.
