The so-called Ghoul Planet is a skull shaped world that is unique to Earth-5391. By the year 2075 it became the hideout for a gang of space pirates who used advanced technology to raise an army using stolen bones creating a skeleton army. The skeletons were then used on raids, attracting the attention of the Space Sentinels peacekeeping force. Space Sentinels Speed Carter, Johnny Day and Crash Morgan were instrumental in stopping the space pirates by smashing their machines disabling their ghoulish army and the space pirates were taken into custody.^[1]
