Xeen Arrow is the superhero protector of Dimension Zero, a world inhabited by telepathic super-giants. In his secret identity he is a leading scientist. Green Arrow and Speedy met him when they were accidentally transported to his dimension. Despite being tiny in comparison, they assisted him in arresting a duo of bank robbers. He then helped them return home, explaining that the passing of a comet had caused the dimensional rift allowing them to enter and the hole would only last for seconds more before he fired them into it on one of his arrows. They kept his giant arrow as a trophy from their adventure in the Arrowcave.
- This version of Xeen Arrow (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
