An astronomer named Mark Langley would send out powerful radar waves through a transmitter to look for other planets in the solar system. Mark discovered a gigantic planet behind Jupiter he would call Planet X. Mark wanted to see if their was life on that planet so he tried to communicate with anyone through the transmitter. Goom would follow the radio signal back to Earth and eventually arrive in his rocket ship. Goom held Mark and his wife captive and told them they would be needed to help him conquer the planet. Goom told Mark to tell the earthlings that he came in peace and wanted to speak to the leaders on Earth or his wife would fall prey to his neutron beam. Mark reluctantly agreed and news of Goom's arrival was on the front page of every newspaper. Goom told the leaders to prepare for the new order and that he would rule mankind. Goom displayed the power of one of his weapons where he placed a human inside a reverse time machine and the man inside reverted back into an infant. Goom displayed more of his abilities by lifting the entire city with the power of his mind and creating a force field to protect himself from any weapon. While Goom was distracted, Mark sent out more radar waves to Planet X and was able to make contact with someone. Mark provided Earth's location and two rocket ships eventually arrived. Several people of Goom's race appeared and told the earthlings that they opposed all violence. They told the earthlings that Goom was an outcast, dubbed a renegade in their society. They apprehended Goom and took him back to Planet X.
Goom was created by Jack Kirby in 1961 and first appeared in Tales of Suspense # 15.
