Fictional character biography
Jonathan Darque was the chief executive officer of a mining company investigating new and cheap sources of energy. His investigations were opposed by environmental activists, who held demonstrations at his trial bore sites. His wife died in a car crash when attempting to evade the activists' blockade. Darque used his engineering skills to design a battle suit allowing him to become Magma. He then developed an underground crime organization.
Darque/Magma created a device he called the Long Range Sonic Stata Scanner (LRSSS), which enabled him to discover the epicentres of earthquakes before they erupted. He also used the machine to generate waves causing earthquakes; this enabled him to blackmail the Mayor of New York City. (At the publication time of this story, the historical Mayor was Ed Koch). Magma held a press conference to reveal his plans. Spider-Man and Iron Man joined forces to drill down vertically to reach the source of the earthquake, where they discovered his hidden base. After Magma was defeated by Spider-Man and Iron Man in a battle on the surface, he escaped in a pod into the middle of the Atlantic Ocean. Spider-Man aimed the LRSSS at this location and Magma was engulfed by the resultant waves and he disappeared into the depths of the ocean.
Magma was eventually arrested after several attempts to take over Stark Industries and some battles on the surface with Jim Rhodes in the Iron Man armor.
