One thing Marvel fans will learn about Kang is that sometimes he spots moments in history that interfere with his long-term plans down the road, and interjects in an attempt to better his status in the future.
This is one of those times, as Kang saw his plans as future ruler thwarted by the then-leaders of the mutants, Eimen and Uriel.
The twins are the sons of “the final Horsemen” of Apocalypse, Ichisumi and Archangel, and a formidable duo that, you guessed it, were abducted by Kang as children.
There’s a real theme to Kang’s plots we should really address at some point.
