If the world needs a hero, can you imagine how much courage it might take to immerge from the anonymous mass of eight billion people to say: "I'm your guy"? It takes an exceptional character to jump right into danger, not for your own benefit but for the world as a whole. But if you take this massive risk, accept that gigantic amount of responsibility, and do what nobody else dared to do, how can you expect everything to go smoothly all the time? Super-Kiwi messed it all up and now they have to live with the consequences. It's tough, but that's what responsibility is. Putting your own head next to a gun that might misfire.
How will they live with the blame and humiliation the people will show them? Will they seek the errors with others or with their own actions? Could they have known about the second missile? Were their actions even justified in the first place. Shouldn't they have been more rigorous, more careful and more conscious about what they were doing? Was it their hunger for fame that drove them after all?
Before Super-Kiwi is able to save the world, they'll have to confront their greatest nemesis: themselves.
