A NASA crew bound for the red planet is captured by its hidden Martian inhabitants, and Invincible tags along to protect them. The rescue succeeds, but a fateful swap leaves one astronaut behind, planting the seed of the Sequid crisis to come.
Following the murder of the Guardians and the Flaxan invasion, Cecil informs Mark that astronauts have been sent to Mars and asks him to shadow the two-week mission. Aboard the spacecraft, Mark adjusts to weightlessness and hardened food while staying out of sight, then slips away to explore the Martian surface alone in search of the planet's buried inhabitants.
He is swarmed by Sequids, aggressive parasites with a history of destroying worlds, and fights them off before reaching a hidden Martian city. There the Martian Emperor explains their long war with the Sequids, kept in check only by the Martians' shape-shifting, which the parasites cannot bond with. Fearing the creatures might claim human hosts, the Martians sentence the astronauts to death, but Mark tricks his captors and hauls the crew back toward their ship, carrying them through a pursuing horde with his strength and speed.
During the frantic takeoff, Rus Livingston is knocked out and left behind unnoticed, and a Martian shape-shifter takes his place among the returning crew. Down on the surface, the abandoned Rus is overtaken by the Sequids, and the parasites turn on the shocked Martians, beginning their conquest of Mars.
Invincible rescues three of the four astronauts and returns them safely to Earth. Rus Livingston is left on Mars and possessed by the Sequids, while a disguised Martian secretly replaces him aboard the ship.
The Sequids begin overrunning Mars, marking the true genesis of the Sequid threat that would erupt on Earth later.
The event debuts in the fourth Season 1 episode, Neil Armstrong, Eat Your Heart Out, set in the Thragg Era during the fall of 2022, and later reappears as a flashback in the fifth Season 2 episode. It sits between the Flaxan Invasion and the Machine Head Takedown, running alongside Nolan's Odyssey.
This mission directly sets up the major conflict of Season 2, when the Sequids and their host return to threaten Earth.
