Man-Wolf

John Jameson aka Man-Wolf is a former astronaut who worked for NASA. 2 years before his wedding Jameson took a mission to the Moon with NASA to explore more of it, and while exploring he found a mysterious gem which suddenly turned him into a werewolf. He was later found by SHIELD and Spider-Man after a missing report came from his father J. Jonah Jameson and he was rescued and saved from being taken over by the gem at least temporarily. After his wedding to a friend of Spider-Man's was called off due to Emma's change of heart he went back to being an astronaut for NASA. Sometime during his second mission to the Moon he picked up a similar mysterious gem making him into the creature known as Man-Wolf once more. He soon went back to Earth after the transformation wore off, but it ended up coming back once he reached home, thus it lead to him coming across the Group of Villains and soon becoming a member though his wolf appearance became slightly more permanent as the Group of Villains experimented on him. Soon this lead to man confrontations with Spider-Man and War Machine.
