It all started with the birth of a bioluminescent baby in Qingquing city, China. That marked the first appearance of peculiar abilities that would come to be known as Quriks. More and more holders of these abilities were born, and now the world has become a super-powered society, where nearly 80% of the total population has some kind of Quirk. A new vocation arose in this chaotic world: the hero. Heroes are a select group licensed by the government to use their powerful Quirks in service to society. But this age also has another type of hero. Nobody chooses them. These illegal heroes act on their own initiative. What is their brand of justice? Can they even be called heroes in the first place? This is the story of vigilantes trying to become real heroes, and the early events of when Ben Tennyson first got the Omnitrix. PLEASE DO NOT REPOST THE STORY OR THE ARTWORK.
