Volcana (Marvel)

Volcana (Marsha Rosenberg) is a fictional character (a supervillain turned superheroine) appearing in American comic book published by Marvel Comics. The character first appeared in Secret Wars #3 (July 1984) and was created by Jim Shooter and Mike Zeck.

Marsha Rosenberg is a day care employee from Denver who, along with her friend Skeeter, is transported to Battleworld during the events of Secret Wars. Seeking power and respect, she and Skeeter agree to serve Doctor Doom in exchange for superpowers. Utilizing alien technology, Doom gives Rosenberg the ability to transform into a molten lava-like form and generate powerful thermal energy blasts. Taking the name Volcana, Rosenberg allies with Doom and battles She-Hulk. During the series, Volcana develops a relationship with the supervillain Molecule Man, Owen Reece.

Some time later, Volcana accompanies Molecule Man and the Fantastic Four to the Beyonder's universe. She separates from the Molecule Man when he and the Beyonder are fused into a Cosmic Cube. Unlike her friend Skeeter, who became the supervillainess Titania, Volcana also operates as a superhero.

Volcana assists the Avengers in repairing the damage to the Earth's crust caused by the Beyonder. Volcana later takes a comatose Molecule Man to an army hospital. After Molecule Man recovers, he and Volcana are allowed to return to their apartment in Denver.
