Never mind, I answered my own question with a bit of research.
A bit of a bio on John Jameson:
Son of J. Jonah Jameson and his first wife, John was an outstanding student who became an astronaut. During a mission, he contracted a virus that gave him superhuman strength back on earth. J. Jonah talked him into fighting Spiderman, but he was defeated. Later, he flew to the moon to collect rock samples. There he found a red gemstone, and turned it into a pendant he wore. Unfortunately, the light of the moon on earth made the gem melt with his skin and turned him into a sort of werewolf. He got defeated once more by Spiderman, who tore the gem out of him and threw it into the Hudson River, but Morbius exposed him to it once more while searching for a cure for his vampiric sickness. He became once more the Man-Wolf and began a rampage on NY that Spiderman had to stop. This time, he left NY and was returned to the NASA by SHIELD. He was sent to an orbiting spacestation which had been invaded by beings from another dimension. Amazingly, the stone also had come from that dimension. He went with them to their realm just to leanr that the gem was the essence of their ruler, a wolf-like being named Stargod. He had sent the gem to other dimension to search for a sucessor and John became just that for sometime. He helped the people in the realm until they were out of harm and returned to Earth, where he discovered that the gemstone was slowly poisoning his body. Spiderman asked Dr. Curt Connors for help to remove it from Jameson's body. For a while, he served as a pilot for the Avengers, until evil geneticist Arnim Zola returned him to his wolf self briefly before being defeated by Captain America.
