Thanos is a supervillain and antihero recognized as one of the most formidable foes in the Marvel Universe. Born on the moon of Titan, Thanos was originally an outcast due to his Deviant gene, which gave him a grotesque appearance compared to his Eternal kin. Obsessed with death from an early age, he sought ways to gain ultimate power and impress Mistress Death, personified as a female figure in his psyche. His obsession led him on a quest for the Infinity Stones—a collection of six powerful gems that control various aspects of existence. With the assembled Infinity Gauntlet, Thanos famously wiped out half of all life in the universe, leading to iconic conflicts with the Avengers and more. Over the years, Thanos's portrayal has evolved through comic books, animated series, and notably in the Marvel Cinematic Universe (MCU), where he became an essential character in the Infinity Saga. The character has been expanded upon in films like 'Avengers: Infinity War' and 'Avengers: Endgame'. His philosophical views on balance, sacrifice, and destiny resonate deeply within his narrative arc, questioning morality and the means to achieve peace. Through these interpretations, Thanos has solidified his place as not only a villain but a complex character shaped by tragic flaws and immense ambition.
