While the Kree-Skrull War is an iconic Avengers storyline, it’s not the most well known to the public.
The eight-issue storyline followed the Avengers as they found themselves and the planet Earth stuck in the middle of a long standing intergalactic conflict between the Kree and the Skrull.
The story arc occurred in pages of Avengers #89-97 in the late ’70s.
The story is kicked off by the arrival of Captain Marvel (the original one, the Kree Mar-vell) on Earth, where his alien presence sends the populace to fear extraterrestrials and hate the Avengers for not cooperating with the recently formed “Alien Activities Commission.”
