Molten Man

Mark Raxton, known as Molten Man, is a Marvel character who gained a molten metal body after exposure to an experimental alloy. His powers include superhuman strength and resistance to extreme heat, making his body nearly impervious to injury. He is the stepbrother of Liz Allan and has clashed repeatedly with Spider-Man. Molten Man's abilities come with the risk of his body melting uncontrollably, a condition that has been treated to restore him to normal at times.
