A member of the Eternals of Titan, Thanos was born of Alars (Mentor), founder of the second colony of Eternals of Titan, and Sui-San, the last survivor of the original Eternal settlement. A mutant, Thanos was born with gray leathery skin and a massive body.

A morose child, Thanos became obsessed with the concept of death. As an adult he left Titan and amassed a large private army composed of soldiers, mercenaries and malcontents from other star systems. Returning to Titan with a small star fleet he attacked his home world with nuclear weapons, killing thousands, including his mother Sui-San. Declaring himself ruler of Titan he set his sights on Earth.

Thanos at some point in his life met the embodiment of Death and developed an amorous relationship with the god of entropy. Thanos' goals have been largely in the pursuit of winning the love of Death. His obsession with winning Death's love eventually drove her to reject him and she has cast him from her realm for all eternity, essentially grating Thanos immortality, but denying him his greatest wish. Undaunted, he continues to seek a way back into Death's favor causing the universe to wonder when next will strike Thanos the Mad Titan.
