A hero within a heart (ArrowverseAvengers crossover) by YouDidn'tSeeThatComing616 reviews
Heroes come in all shapes and sizes. You don't need powers, nor a muscular body to become a hero. A hero is a verb, not a noun. You could be a hero for 5 minutes, or for your entire lifetime. A hero is just someone who is brave for a little bit longer. I could be a hero, So could a stranger on the street you just met. So don't tell me who a hero is and who he isn't.
