On a later mission, Jameson was infected with spores that gave him superstrength, but strained his body and mind. He was forced to wear a strength-restraining Jupiter suit and battled Spider-Man at his father's urging before recovering and calling himself "Colonel Jupiter". His father convinced him to go after Spider-Man, who had been seen apparently robbing a bank. The web-slinger outsmarted him, and Jonah soon learned that Spider-Man was saving the bank from a bomb. However, Jameson did not care about the misunderstanding and was really out for revenge. Spider-Man managed to neutralize the spores with electricity, returning Jameson to normal.
