Son of Mentor and San-Sui, brother of Eros, Thanos is an Eternal, a resident of Titan. At a young age, Thanos became obsessed with death. Expelled from Titan because of crimes he committed, Thanos would eventually return to Titan, unleashing a nuclear attack which killed his own mother.
Eventually, Thanos became aware of the object known as the Cosmic Cube, which Thanos hoped to use to raise his status from Demigod to God. Foiled by Captain Marvel, Thanos seemingly died in combat.
Not dying so easily, Thanos reincorporated his body and offered his services to Adam Warlock in battle against the Magus and the Universal Church of Truth. It was in these battles that Thanos learned of the Infinity Gems for the first time which would become his obsession for the majority of his life.
Eventually Thanos would be turned into a statue by Adam Warlock, only to be returned to life years later by Death herself.
Thanos then set out to create the Infinity Gauntlet in order to wipe out half of the population of the universe.
In later years, Thanos has seemingly reformed his evil ways, it remains to be seen if these changes are permanent.
