Synopsis for Green Arrow: "The World's Worst Archer!"
Trained in archery by Brave Bow, an Indian his father once rescued, Roy Harper attempts to impress Green Arrow with his archery skills. However, every time he tries to show Green Arrow his abilities, the arrows seem to veer away from their appointed targets. Not giving up, and helping Green Arrow stop some robbers, both soon learn the reason why Roy's arrows never hit their targets: The non-flit arrows were vulnerable to the magnets inside the Arrowcar. Afterward, Green Arrow accepts Roy as his new partner, Speedy.
