Manchuto was the Leader of the Nebulan Elite, a small armada who protected the inhabitants of the distant purple moon of Kalanor. For many years the inhabitants enjoyed peace and prosperity. Then one day, the tyrant known as Despero, attacked and attempted to absorb the nuclear properties of the purple mist that embodied the moon with the purpose of enhancing his own powers. Overwhelmed by Depsero and the sheer power of the Flame of Py'tar, the members of the Nebulan Elite called upon their fearless champion and guardian Manchuto. Despite his mastery of mind over matter, Manchuto was unable to push back the tyrant's attack, although he was able to hold his position just long enough until Martain Manhunter and Jon Stewart of the Justice League arrived and help defeat Despero.
