Kang the Conqueror Reading Order!
Time based hijinks are a well known trope in comic book history. While DC typically has Booster Gold and the Flash to thank for timeline troubles, in the Marvel Universe, Kang The Conqueror is usually to blame.
Kang, whose first Marvel appearance can be tied back to 1963, was born Nathaniel Richards in the 31st century on an alternative peaceful earth (earth-6311). Kang stumbled upon time travel technology developed by Doctor Doom and has been a major threat to the Avengers and earth itself over the past 60 years.
Due to Kang’s constant abuse of time, the Marvel universe is filled with alternative versions of Kang. These Kangs have been known to operate independently of Kang, in support of, or usually against Kang.
