Titan is a fictional location appearing in American comic books published by Marvel Comics. It is depicted in the Marvel Universe as the home of the Titanian Eternals on Saturn's moon Titan. It first appeared in Iron Man #55 (Feb 1973) and was conceived by Jim Starlin and Mike Friedrich. The Titanians, also known as Titans, were later retconned as being an offshoot of the Eternals, which had been created separately by Jack Kirby.^[1]

Titan appeared in the 2018 film Avengers: Infinity War and 2019 film Avengers: Endgame as a ruined planet and the former home of Thanos.

Fictional history

The colony of Titanian Eternals was founded about 750,000 years ago in the aftermath of a devastating civil war among the first generation of Earth's Eternals. The Eternals Uranos and Kronos led opposing factions, which clashed in a conflict of ideals over the Eternals' destiny as a people. Kronos' side prevailed, and Uranos and his surviving followers were exiled into space and landed on the planet Uranus. There, they discovered a supply depot guarded by Kree Sentry #213. When the Eternals destroyed the Sentry and raided the outpost, the Kree armada came to investigate, thinking Earth's solar system to be devoid of intelligent life. The armada destroyed the Eternals’ spacecraft, forcing them to crash on the moon Titan, where they hid from the Kree. There, the small group of survivors formed a colony beneath the surface of the moon, employing artificial life systems. These Eternals eventually fell prey to internal strife, and all of them but Sui-San were killed. Mentor, who had gone into voluntary exile, arrived on Titan, and the two Eternals began to repopulate the Titan colony.^{[volume & issue needed]}

These new Titanian Eternals achieved much scientifically and socially, not the least of which was ISAAC, an immense computer system that could monitor and maintain all of the life support functions of the inner world.^{[volume & issue needed]}

Under A'lars' leadership, Titan became a haven for peace. Then, A'lars (also known as Mentor) sired the last two of his numerous children: Eros and Thanos. Thanos was born a mutant, and grew up with dark visions of conquest and destruction. Thanos left Titan, recruited an army of mercenaries, and returned to attack. Only a hundred of Titan's thousands of inhabitants survived, and Sui-San perished in the slaughter. Eventually, the Titanians rebuilt the colony and restored it to a place of meditation and the pursuit of knowledge.^{[volume & issue needed]}
