Karsta Wor-Ul is a Kryptonian soldier that settled on Earth. Decades before Krypton exploded, it was the center of a mighty interstellar empire. Kryptonian soldiers, empowered by yellow suns and equipped with incredible technology, pushed all foes before them. In this force was the young Karsta Wor-Ul. However, debate on krypton was not kind: ultimately, it was decided that the power of empire (and the yellow suns) was detrimental to moral fiber. The Military Council was voted out in favor of the Science Council, and the troops were recalled.
