John Jameson is the son of J. Jonah Jameson and an astronaut for N.A.S.A., the reason he is one being due to his estranged relationship with his father like in the Marvel Comics. However, the discovery of the Godstone during a space expedition causes him to transform into the lycanthropic Man-Wolf. He debuts in the Ultimate Spider-Man episode "The Man-Wolf".
Man-Wolf was created by Stan Lee and Steve Ditko.
In his human form, John Jameson is a Caucasian man with blond hair. In his Man-Wolf form, he looks like a classic werewolf covered in white fur with an armor and wields a sword.
Powers and abilities
As the Man-Wolf, John Jameson has incredible speed, strength, and senses. He has razor sharp claws, and a sword. In addition, he can allude Spider-Man's Spider sense, breath in space, and absorb energy.
Spider-Man's team and S.H.I.E.L.D. answer a distress signal coming from J. Jonah Jameson to look for John Jameson on the moon, where John was supervising the construction of a Daily Bugle communications station. Onsite, however, the construction crew found the remains of an advanced civilization harboring a number of strange jewels, one of which embedded itself in John's chest and triggered his transformation into the feral Man-Wolf (with the trappings and the sword used by Stargod). Spider-Man manages to shatter the jewel, but the sudden reversion causes John to retain some wolf-like appearance and features, whereupon he is kept in S.H.I.E.L.D. custody for treatment.
