On another occasion, when Nitro's lawyer had him released from captivity, the villain immediately escaped, attempting to rob a bank for money to travel to San Francisco to kill Captain Marvel. He was opposed by Spider-Man, who defeated Nitro by webbing a barrel of tear gas to his body right before he exploded. As Nitro reformed, the suddenly evaporated tear gas mixed with his own molecules, leaving him violently ill and unable to fight back. Again, Nitro was arrested and sent to jail.
