Origin
Shortly after Green Arrow emerged in Seattle, a young Junior Diaz watched the vigilante bring and embarrasses his father, a corrupt businessman involved with numerous illegal activities. Though Diaz hated Green Arrow for what he did to his father, he was also inspired by the man in the hood, because like the other superheroes and vigilantes emerging at the time, Green Arrow proved to Diaz that one could become more than man. With that thought in mind, Diaz began to travel the world following secrets and whispers to the League of Assassins city known as ‘Eth Alth’eban, where he would train under martial arts master Richard Dragon. While Dragon taught Diaz all he knew about fighting, he also attempted to teach values such as empathy and compassion, which Diaz did not believe in. After getting everything he needed from Dragon and rejecting the teachings of many virtues, Diaz apparently killed his master, and assumed his name, returning to Seattle to take over the city and destroy Green Arrow.
Creation
Junior Diaz was created by the acclaimed Green Arrow creative team of writer Jeff Lemire and artist Andrea Sorrentino. Initially, he was believed to be a drastically altered version of Richard Dragon for The New 52 continuity, but was later revealed to be a man assuming the name of Dragon.

Together they take out Diaz’ men and after taking down a crowd the only man left is Junior, holding arrows he had caught.

He proceeds to beat Oliver senseless with very direct attacks keeping track of what he has done and what state Oliver is in. Diaz explains to Oliver how he’s a disappointment, after how he changed himself into something better for revenge and it was an impostor who beat his father, then Oliver was beat so easily by Junior with his bare hands. Oliver then tells Diaz no matter how much he talks or how much money he throws around, he’s nothing, just like all the other two-bit thugs, and the difference between Diaz and Oliver, is that he’s not alone. Diggle then pulls the arrow from his hand and tosses it to Oliver who stabs it through Juniors leg, telling him he severed the femoral artery and if he doesn’t get medical attention he will die, to which Diaz replies “This isn’t over”.
