So this happened... Yep... I made his shitty original design look cooler. STORY IS BE DO YES!
In the alternate reality of Earth-2, the Justice League of America had never be formed, however the Justice Society of America was still active, and recruiting new members, such as Batman and Superman. Robin, Dick Grayson, fought side by side with Batman until it was time for him to go off to college, as he continued a solo career as Robin at that time. In his third year of college, he decided to retire, feeling he can't be the "Boy Wonder" forever. As the years went by, Bruce Wayne eventually married one of his villains, Selina Kyle, and had a daughter, Helena Wayne. His daughter, once old enough, would then fight by his side as "Robin, The Girl Wonder." During an invasion on Earth in Central City, led by Darkseid, Bruce recommended his daughter leave the city to protect herself. Following his order, in the distance she could see behind her the large scale explosion, destroying all of Central City, and everyone in it, including her mother and father. The Joker heard of Batman's death, and went on a rampage, believing his rival and only reason for living died before he could.. Dick, seeing the danger the Joker posed, decided to dawn the cowl and fight the Joker as Batman. After defeating the Joker with the help of Helena, she told Dick Batman died with her father, and deserved to stay that way. Dick decided it was time to dawn a new Batmanesque suit, returning as "The Robin" fighting as one half of the new Dynamic Duo, with Helena, now as "The Huntress," to protect Gotham.
