Train the Hero

In this universe, most people in the world gained superpowers, due to a mysterious explosion whose origin is unknown. The explosion not only affected people, it also affected some animals, objects, etc. Afterwards, people began to attack each other, because the explosion caused rare mutations in certain people, such as people with animal features, half-machine humans, others with an appearance similar to fictional aliens, among other cases. This is where heroes are born, who sacrifice their lives to save everyone (at least that's what they show). In this world you make the decision to be a hero and create your own story, but you decide what kind of hero you want to be.
