superhero is a hero with super powers for example সুপারম্যান অথবা flash and it doesn't mean that superheroes cannot be humans. Now ব্যাটম্যান is not a superhero neither is Green Arrow, they're just heroes
A superhero is a person অথবা living thing that puts there life out for others.Even sacrificing themselves for their loved ones.That's what makes a superhero. Not super powers.
