Creation Story
Thanos is Jim Starlin’s creation. Starlin was a new Marvel artist in 1972 when he designed Thanos for his first major Marvel writing-and-art assignment. Iron Man #55 (February 1973) introduces Thanos alongside Drax the Destroyer in the same issue. Starlin plotted and pencilled; Mike Friedrich provided the dialogue. Starlin has stated in interviews that Thanos was inspired by Jack Kirby’s New Gods, particularly Darkseid, with additional philosophical framing drawn from Starlin’s personal reading in cosmic mythology.
Starlin moved Thanos into his Captain Marvel run almost immediately. Captain Marvel #27 (July 1973) is Thanos’s first cover appearance. The Starlin Captain Marvel run (1973-1974) built the cosmic Marvel mythology that has defined the corner of the Marvel Universe ever since: Thanos as Mad Titan, the Infinity Gems, Death as a cosmic entity, the Avatar of Death framework.
The Infinity Gauntlet
Infinity Gauntlet #1 (July 1991) is the most commercially and culturally consequential Thanos story. Jim Starlin wrote; George Perez pencilled the first four issues (with Ron Lim finishing the final two). The six-issue event has Thanos assemble the complete Infinity Gauntlet and use it to eliminate half of all life in the universe. The story is the direct source material for Avengers: Infinity War (2018), which earned $2.05 billion worldwide, and Avengers: Endgame (2019), which earned $2.80 billion.
Starlin’s 1991 event established the Thanos-snap narrative framework that the MCU adapted nearly beat-for-beat. The book is widely regarded as one of the most important cosmic Marvel storylines and has been republished numerous times across trade paperbacks, omnibuses, and Marvel Masterworks collections.
The MCU era
Josh Brolin’s Thanos across Avengers: Infinity War and Avengers: Endgame made Thanos one of the most recognizable comic-book characters of the 2010s. Brolin’s motion-capture performance, the Russo Brothers’ direction, and the Markus-McFeely script collectively adapted Starlin’s cosmic mythology for mainstream audiences. The films’ collective gross (nearly $5 billion across the two Avengers entries alone) makes the Infinity Saga’s finale one of the most commercially successful multi-film events in cinema history.
