John Jameson a Marvel Comics character and supervillain. He is the son of J. Jonah Jameson and an astronaut for N.A.S.A. The reason why is 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".
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.
In the episode "Osborn Academy", John Jameson is among the people that audition for a spot in Osborn Academy where he shows his space program knowledge. In the episode "Halloween Moon", John Jameson and Harry Osborn worked on an experiment that involved a lunar crystal that fed off gamma radiation which turned John Jameson into Man-Wolf whose scratch turned those who were struck by Man-Wolf's claws into werewolves. It took Spider-Man, Hulk, Gwen Stacy, and Harry Osborn to undo the effects of the Man-Wolf transformations and cure the infected. While Norman Osborn was displeased that he got Harry involved upon being given the lunar crystal, John Jameson stated the Man-Wolf form had a different personality as Norman Osborn plans to find a way to fix the lunar crystal's effects.
